The original bass has no directionality. Therefore, it is difficult to determine its source. Let's look at how to properly install a subwoofer in a car to achieve high-quality sound.
Selecting a location
Front center (1)Good position. Good connection with the front speakers helps to expand the transient frequency. Although in cars with limited space in front, such an installation is not possible. This method is suitable for minibuses. Since there is not much space there, a small closed enclosure has to be used for the subwoofer.
Luggage compartment, forward facing (2)
This method is very popular. However, if there is not enough space between the subwoofer and the opposite wall of the luggage compartment, the sound wave emitted by the subwoofer will be subject to pressure and the bass quality will suffer. As for sedan or coupe cars, the damped sound wave of the front speakers, reaching the trunk, changes phase to the opposite one. And if you open the trunk, the sound becomes unexpectedly loud. Usually the reason for this is the internal layout.
Luggage compartment, rear facing (3)
This is a good way. But in cars such as a sedan or coupe, the behavior of the sound wave will be the same as in the previous case. To correct this effect, you should use a sufficiently large acoustic screen, remove obstacles in the path of the sound wave, or reduce the size of the housing. Hatchback cars or vans do not have this problem.
Flush with floor (4)
The flush-to-floor method is applicable to the trunk where the tires are stored. The trunk floor successfully serves as an acoustic screen; the bass acquires good spaciousness and energy. This method can be used in different types of cars - sedan, coupe, station wagon, except for models that do not have space for spare tires. Moreover, installing a large-diameter subwoofer can cause problems, since there is not much space there.
Rear shelf (5)
This is a good position for the sedan and coupe. The placement of the subwoofer there must be very strong enough to withstand the pressure of the sound waves and its weight.
Important points when installing a subwoofer
Case weightBass energy causes surrounding objects to resonate. Each of them begins to produce sound at its own frequencies, which leads to degradation of the musical bass. To produce the cleanest, most uncontaminated bass possible, the subwoofer cabinet should be as heavy as possible so as not to resonate itself and spread the resonance. If the car is not excessively heavy, then the more weight the body has, the better the bass.
A good vibration dampening effect is achieved by using insulating material inside the housing, which is used in home speaker systems.
Material selection
For the speaker housing, you should choose a material that has the least resonance and does not drown out the sound. The most suitable material for car acoustics is wood. Fiberboard (fibreboard) is a very good material: cheap, heavy, difficult to resonate and easy to process. Birch and oak are also good: heavy and difficult to resonate, although the roads are difficult to process. It is best to use slabs thicker than 18 cm.
Sound-absorbing material is necessary, but not in too large quantities.
Sound-absorbing material is needed to reduce the effect of standing waves inside the housing. But if you use too much of this material, the sound becomes compressed and the speaker's output decreases. Adhere sound-absorbing material to at least the back wall inside the case, or at most to the back, top, and bottom walls inside the case. It is better to use sponge material, because... it has better sound-absorbing properties.
Differences in sound depending on shape
Rectangular. Such a body is easy to manufacture, but is prone to the formation of peaks above F3 and dips after F3. Leveling the characteristics is achieved by such methods as installing a reflective plate inside, reducing the parallel phase, and using sound-absorbing material.
Trapezoidal 1. Although the hump on the energy characteristic curve smooths out a little, the dip after the peak still remains. Moderate use of sound-absorbing material is advisable.
Trapezoidal 2. The characteristic is smoother than in the two previous cases. If the corners of the case are rounded, the characteristics will become even smoother.
Trapezoidal 3. Another trapezoidal shape is superimposed on the front part of the trapezoidal body 2. The curve takes on a smooth, sloping shape and the sound becomes more energetic.
Installing a subwoofer in the compartment where the spare tire is stored is called flush mounting. The floor of the luggage compartment forms an acoustic shield, convenient for the propagation of low frequencies. And if we can lower the transition frequency at the junction with the front speakers, this will be the best place to install a subwoofer.
Drive with the breeze and high-quality music along a highway with beautiful scenery. Isn't this what every car enthusiast dreams of? And it seems like everything is there - a car, music, and the beauty of nature outside the window. There's just something missing. Most often, this “something” is the volume of sound, its depth, which can only be achieved by installing a high-quality subwoofer. At first glance it may seem that there is nothing complicated about this. Whatever the case. Many car enthusiasts have no idea where they can install such a useful device for maximum efficiency. In this article we will deal with all the questions that interest you in more detail.
Installing a subwoofer in the trunk so that it plays into the cabin through the hole in the back of the rear seat
Theoretical information
Let's look at what types of acoustics are generally used in a car. Four types of systems are popular - the so-called infinite acoustic screen, closed-type acoustics, strip-type acoustics and a case with a bass reflex. I would immediately like to note that the use of complex acoustics for the low-frequency head makes it possible to install lower-power amplifiers. However, it remains at the same level. Considering that the cost of an amplifier largely depends on its power, this aspect is very important.
When purchasing a subwoofer, you need to ask how many voice coil windings are in the device. Today, “low-frequency drivers” with 1, 2 or 4 windings are on sale. In principle, increasing the number of windings is some trick of manufacturers, who enable customers to use several devices of lower power instead of one powerful amplifier.
The so-called active cabinet subwoofers, which are sold in conjunction with an amplifier, are very popular. In this case, the car enthusiast’s task is simplified, because the time for choosing devices is significantly reduced. And it always remains on top. The advantage of active subwoofers is simplicity and high speed of setup. In addition, they are easy to install and are equipped with all necessary inputs. But there is a drawback - there are no inputs from the built-in amplifier. This means that if it burns out during operation, the speaker itself will no longer be usable.
Installing a subwoofer in a car: where, how and why
Actually, it’s no secret to every experienced car enthusiast that installing a subwoofer in a car largely depends on the vehicle’s body type. Moreover, today there are three main classes (of course, this is conditional) - convertible, sedan and hatchback (station wagon). Each type must be considered separately, which is what we will do next.
Installing a subwoofer in a sedan
One of the options for installing a subwoofer in a sedan
So, let's start our excursion with one of the most difficult options - installing a woofer in a sedan. There are “craftsmen” who install a subwoofer in the trunk or mount it in the side wall, believing that this is enough. But this is the wrong approach. With this method of “installation”, only the lowest frequencies will reach people in the cabin, and this will happen due to the body elements. Therefore, there is no need to talk about any sound quality. What options are there?
There are several of them:
1) Installing a subwoofer in the rear shelf. This method is considered the most convenient and promising in terms of sound quality. Moreover, the car enthusiast has the opportunity to use a variety of sound design options:
— endless acoustic screen. One of the simplest ways. But here it is necessary to acquire special low-frequency heads, without which it is impossible to achieve high sound quality. In addition, the task of the car enthusiast is to completely separate the trunk from the passenger compartment. This is easy to do - you just need to seal all existing holes. The next step is to redo the rear shelf. It is desirable that it be made of thick MDF board. As a last resort, you can use regular plywood or a sheet of chipboard. The use of these materials will avoid rattling of the speaker. In general, the thicker the rear shelf, the better for overall sound quality. In addition, a thick shelf allows you to “get” the subwoofer out of the trunk a little and save time on creating a hole for it.
To prevent the speaker from breaking down after just a few days of active use, it is very important to use a special infra-low frequency filter (the ideal setting in this case is about 30 Hz). With such an installation, we must not forget that the quality of low frequencies will directly depend on the contents of the luggage compartment;
— closed body. Unlike the type of installation described above, here the woofer must be installed in a closed box with a volume of approximately 20-30 liters. Thanks to this, the sound quality will not greatly depend on the fullness of the trunk itself. But this method also has disadvantages - it is necessary to modernize the rear parcel shelf to install the structure, and also to come to terms with the loss of volume in the luggage compartment;
Something else useful for you:
— strip type housing. This method of installing a subwoofer is one of the most attractive in terms of sound quality and power. With proper installation, you can achieve a pressure increase of up to 5-6 decibels. In this case, the woofer head is completely closed, which eliminates the possibility of damage. In addition, there is no need for tedious space between the trunk and the car interior. In this case, you don’t have to invent anything, but use ready-made cases. This method has one drawback - its large dimensions, but this is what scares off most car enthusiasts;
— body with bass reflex. If you install the subwoofer this way, you can expect an increase in pressure of up to 3 dB. But the phase inverter port should be located at a minimum distance from the woofer head. The installation of a housing with a bass inert is carried out in the same way as in the case of a closed housing. The only thing is that you will have to carry out additional modernization of the rear shelf due to the large volumes of the subwoofer.
2) Installing a subwoofer in the armrest in the rear seat
Installing a subwoofer in the armrest in the rear seat
Some cars have a special hole on the armrests, which is a must-have for music lovers. The principle here is the same as in the case of installing a subwoofer in the rear parcel shelf. But there are some subtleties. It is important to ensure that the existing holes are of sufficient size and do not “pinch” the subwoofer cone. If you don’t control this moment, you can’t count on high-quality bass. There are situations when the hole diameter is too small. In this case, it is necessary to carry out work to change its shape. If you like to listen to music at maximum volume, then it is better to construct a high-quality wall behind the rear seat. This is where the big speakers crash into. The sound will be simply magnificent in both power and quality.
Installing a subwoofer in a hatchback
Installing a subwoofer in a hatchback
Owners of such cars are very lucky, because problems with installing a subwoofer are solved very simply and quickly. There are a minimum of obstacles between the luggage compartment and the cabin, so installation is completed in a matter of hours. The acoustic design can be anything, except, of course, an endless acoustic screen. But there are some subtleties that you need to remember. By the way, to get more bass, you can point the speaker diffuser at the rear window. If the work is carried out efficiently, but there is still not enough bass (more precisely, it appears only when the door is opened), it is necessary to increase the volume of the woofer head. No place? – Then take a smaller speaker.
Installing a subwoofer in a convertible
And finally, the last type of car is a convertible. Here, certain problems arise with the choice of location - there is a shortage of free space. To achieve good results, you can use any type of woofer design, again, except for the infinite acoustic baffle.
conclusions
Thus, you can always install a subwoofer in your car and achieve maximum sound quality. The main thing is to approach the organization of the process correctly, take your time and choose the right woofer (but that’s another story). Good luck.
Choosing a subwoofer is a rather labor-intensive and responsible matter. It is labor-intensive for the reason that there are quite a large number of nuances that need to be taken into account when choosing. It is responsible because if the wrong choice is made, a decent amount of money spent on equipment and installation can simply be thrown away. In this article we will not answer the question - “which subwoofer is better to install in a car?” and we won’t name “the best subwoofers for cars,” but we will try to briefly describe the process of choosing a subwoofer for a car. This will help you either choose a subwoofer yourself in an online store, or will give you some understanding of what the seller who will select the subwoofer will tell you.
What is a subwoofer for?
A subwoofer is an acoustic component that will be responsible for bass, namely for reproducing the lower range of sound frequencies. Since the rest of the speakers that are located inside the car must be responsible for higher frequency ranges and cannot fully reproduce low frequencies, a subwoofer is necessary for the full sound of the entire speaker system.
Bass character
You should immediately decide what kind of bass you need in your car:
Or it will be a small “add-on” to the main sound - 100-150 W of rated power is quite enough
or it will be high-quality and moderately powerful bass, fully complementing the overall sound picture - 200-300 W
or it will be a very powerful bass that will make the residents of a couple of nearby blocks hate you - from 500 W
Selecting a subwoofer type
Separate subwoofer speaker- involves the manufacture of a housing for the speaker (with the exception of free-air installation) with its subsequent installation, as well as the purchase and installation of a separate power amplifier.
Passive subwoofer- subwoofer speaker in a housing of various designs. Involves the purchase and installation of an external power amplifier.
Active subwoofer- subwoofer speaker in a housing of various designs with a built-in power amplifier.
Selecting a subwoofer based on technical characteristics
Power, W- can be maximum (peak) and nominal. The manufacturer likes to focus the buyer’s attention on the first, although it has nothing to do with harsh reality. It is worth paying attention to the rated power of our subwoofer.
Diffuser diameter, inch- the main geometric size of our subwoofer. The larger it is, the more powerful the subwoofer. The most optimal sizes for high-quality bass are 10 and 12 inches. Less - you may not notice the presence of a subwoofer. More - you can overdo it.
Choosing a subwoofer enclosure design
Closed box- the simplest case design, when the speaker is placed on the wall of a completely sealed box. The least deep and powerful, but dense bass. In terms of the quality of bass output, it is one of the best options.
With bass reflex- a more complex design, implying the presence of a port or slot in the housing. Produces more powerful bass, although there may be a loss in quality, as the bass will be more “blurry”.
Bandpass- the most complex design, when the body is divided into two volumes with a more complex system of outlet ports. Even more powerful, but “blurry” bass.
Selecting an active subwoofer
Standard case- for a subwoofer speaker, even taking into account the installed amplifier, a certain volume of the housing is provided, so you can get very good bass.
Compact body- the most compact design, when there is practically no volume provided for the speaker. As a rule, it is not possible to achieve any decent bass from such subwoofers.
Manufacturing enclosures for subwoofer speakers
Two types of enclosures can be made for a separate subwoofer speaker:
Trapezoid housings- high-quality materials are used for manufacturing (unlike many factory cases), it is possible to adjust the bass to the tastes of the car owner (various volumes and designs), and also make a case of any shape (a more compact installation can be made).
Stealth case- for the subwoofer speaker, a housing is made and installed in any of the niches of the car (usually the wings of the luggage compartment). The best option in terms of “quality-compactness” ratio.
Choosing a subwoofer installation location
Passive subwoofer- almost always installed in the trunk of a car, since that is where the largest amount of free space is.
Active subwoofer- in a regular case it is also installed in the trunk. If we are talking about a compact body, then it can be installed under the seat or on the back of the rear seats of the car.
Subwoofer speaker- if a “trapezoid” housing is made for the speaker, then installation is carried out in the trunk. If a “stealth” body is manufactured, then installation is carried out in the wings of the luggage compartment. It is also possible to install the speaker directly in the trunk shelf (in sedans) - a free-air installation option.
Dependence on the car body
The trunk of a sedan is an isolated volume. The luggage compartment of station wagons and SUVs is connected to the interior. So the same subwoofer will play quieter in the trunk of a sedan than in the trunk of a station wagon or SUV.
Dependence on other acoustics
Since the subwoofer is only one of the components of the speaker system, it must fully fit into the latter. If a low-power subwoofer is installed under powerful acoustics, then most likely it simply will not be heard. If a powerful subwoofer is installed on a weak acoustic system, then most likely only it will be heard. So a logical compromise is needed.
Choosing an amplifier for a subwoofer
If the design of the subwoofer does not include an amplifier (only available in an active subwoofer), then you will need to purchase and install an external power amplifier under the subwoofer (the radio amplifier, which is quite obvious, will not drive the subwoofer). The rated power of the amplifier should approximately match the rated power of the subwoofer, or slightly exceed it.
Choosing a subwoofer manufacturer
Several dozen manufacturers produce subwoofers. Among this diversity there are both well-known names - Alpine, Hertz, JBL, Kicker, Pioneer, Sony, and many very unusual names. Most well-known manufacturers have offers in various directions regarding the types and characteristics of manufactured subwoofers, and some focus on one direction (for example, Mu-Dimension, which produces compact active subwoofers). Well-known brands, as a rule, should not disappoint.
Choice of subwoofers by cost
There are a lot of subwoofers and their prices also vary greatly. If someone is interested in the very fact of having a subwoofer, then you can consider options starting from 1000 rubles. If someone is interested in something bigger, more powerful, more famous, then you can get up to a price of 50 thousand rubles. 5-10 thousand rubles is the same range from which the largest number of subwoofers are purchased.
Installation of subwoofers
In addition to the purchase, you need to take care of the installation of our subwoofer. If you purchase an active subwoofer, you will not have to install any additional components. If the subwoofer is passive, then you will need to install an external power amplifier. A separate subwoofer speaker will require the manufacture of an enclosure (unless it is a shelf installation), as well as the installation of an external power amplifier.
Setting up subwoofers
A purchased and installed subwoofer also requires certain tuning work, without which its sound may somewhat surprise the car owner. There are several positions that require adjustment, but we can highlight the setting of the frequency cutoff of our subwoofer - the frequency range that our subwoofer will reproduce (adjustable depending on the frequency range of the cabin acoustics).
And what is better to choose?
Naturally, it is impossible to give the only correct answer to this question. Everything will depend on two standard parameters - what you want to get in the end, and how much money will be spent on it. If you are focused on good bass, then it is better not to save much on equipment - take either a good active subwoofer (by no means compact), or a passive one with a cone diameter of 10 or 12 inches. If installed or configured correctly, most likely, the car owner will be satisfied with the result.
A subwoofer or sub, as motorists also call it, is an acoustic system that operates at low frequencies (from 5 to 200 Hz). It is necessary to provide more powerful bass, without which it is impossible to listen to modern hits. There are several nuances in how to choose a subwoofer for a car, because the material from which the interior parts are made can degrade the sound quality, and the reproduction of different frequencies will be uneven due to the displacement of the driver's seat relative to the center of the car.
Only a competent approach to selection will allow you to determine which subwoofer is best for your car. More details about the features of choosing a subwoofer for a car will be discussed in this article.
Modern automotive magazines often talk about well-known subwoofer manufacturers, assigning them various ratings. But it's worth asking whether the best subs are for the average driver who just wants to improve the sound of his car a little. This question cannot be called easy, because all people are different and their preferences will be different.
Only the most popular brands are heard of, for example, Sony, Kenwood, Pioneer and so on. All of them are produced at a high level, so there are no serious differences between them. For the average person who does not study in musical institutions, identifying the features of the sound of low frequencies is very difficult, and sometimes impossible. Moreover, if the tuned car then does not participate in various sound competitions, then what is the point of investing a lot of money in branded acoustics?
Not the last place when choosing a subwoofer is the design of the car and its technical characteristics. Agree, it will look ridiculous if you install very expensive and powerful acoustics on an old VAZ 2108, which will only complement the creaks and groans of the V8 body.
On a note! According to a special calculation system, the cost of musical accompaniment should not exceed 20% of the cost of the car itself. This calculation helps many drivers choose the right solution.
Types of car subwoofers
Depending on whether the subwoofer is equipped with a special amplifier or not, they can be divided into active and passive. Let's consider each of these types separately.
Active
The active subwoofer includes a low-frequency speaker, a sound power amplifier and a crossover. This type is best suited for daily use due to its ease of use - you just need to connect it to the radio. If your priority is not surround low-frequency sound and you do not have the desire or time to spend a long time adjusting the sound, then you are better off opting for an active subwoofer.
What active subwoofers are there for cars? Advantages and disadvantages
The main advantages of active types of subwoofers include:
- ease of operation;
- compact design;
- low cost;
- Such a sub can be installed on almost any model.
They also have their disadvantages, including:
- Low quality speakers included;
- the built-in amplifier is not very powerful (no more than 150 watts);
- There are problems with the reproduction of low frequencies (they only lose from 45 Hz, but not lower).
Here are the data for average subwoofers. Of course, you can also find devices that will reproduce lower frequencies, but their cost will be much higher, and the sound quality will be a little lame.
Passive
The amplifier is not included in the design of this type of subwoofer, which is why you will need to purchase this product separately. To achieve the highest quality sound, you need the right combination of subwoofer and amplifier. In most cases, manufacturers indicate in the instructions for the subwoofer how much amplifier power is needed. Otherwise, you need to ask the seller of a specialized store, providing him with a model of the subwoofer.
Types of passive subwoofers The amplifier is not the only product that needs to be purchased separately. Speaker cables are also required. If you have any doubts about whether you can correctly and efficiently install a subwoofer in a car, then it is better to seek help from professionals.
Advantages and disadvantages
Now let's look at all the positive and negative qualities of passive subs. The advantages include:
- advantages of passive subwoofers:
- the ability to manually adjust the sound;
- selection of a combination of subwoofer and amplifier;
- high quality sound.
Oddly enough, this type of subs also has several disadvantages, including:
- difficulties in setting up the product;
- the need to purchase an amplifier separately;
- relatively large dimensions;
- high price compared to active subwoofers.
Despite the high cost, many motorists prefer passive subwoofers, because they are installed on a car for only one purpose - high-quality sound of their favorite tracks on the road. This is why you need an amplifier with manual sound settings.
Classification by design features
Depending on their design features, subwoofers installed in cars are divided into 3 types: open, closed (cased) and compact. Let's consider each of them separately.
Open
This is an ordinary speaker without the usual wooden box, which is mounted in a car panel. It is often installed on the back of the car. Open devices are considered the most affordable, but you have to pay for the low cost of a subwoofer with poor sound quality. When the subwoofer is operating, vibration damping does not occur, which is why the finishing materials resonate.
One of the simplest types of subwoofers is open Case (closed)
Such products are produced in a special box, which has a positive effect on the quality of the music produced. Manufacturers were able to avoid the return sound wave by positioning the speaker ideally relative to the sides of the housing. In this case, the box does not vibrate, which adds its own notes of sound to the music.
Closed-type car subwoofer On a note! If desired, the device can be made manually, taking into account the individual characteristics of your car model. As a rule, ardent fans of high-quality music resort to this option.
The peculiarity of this device is that it is installed under the driver’s seat, which is why it takes up virtually no space. The best manufacturers of compact subs include Mystery, Vibe and Hertz. The compact size does not prevent the subwoofer from delivering clear and powerful bass, and it does not have to be installed under the seat. Many motorists prefer to place the device in the trunk or in any other suitable place.
This is what a compact subwoofer looks like Types of cabinet subwoofers
Cabinetd or closed types of subwoofers differ from their analogues in the complexity of their design. During manufacturing, all housing dimensions are automatically calculated in such a way as to ultimately obtain the highest quality sound. All cabinet subs can be divided into several types, differing from each other in structural properties.
Table. Types of cabinet subwoofers.
| Title, photo | Description |
|---|---|
 BandPass | This subwoofer differs in the location of the low-frequency speaker (woofer), which is located inside the housing. The bass reflex outputs the sound outside. A crossover is not required to connect a subwoofer, but because of this the product cannot be called cheap. |
 Compact-Sub | Based on the name, it’s easy to guess that the main advantage of this subwoofer is its compactness and ease of installation. It is often installed near the back seat. |
 RadPass | This sub consists of two woofers, each of which operates at its own frequency. The job of the additional speaker is to lower the resonant frequency of the sound. Due to the high cost, this type of subwoofer is usually installed exclusively on expensive cars. They are also installed by motorists participating in car audio tournaments. |
 Vented | Drivers also call it a box with a bass reflex. The product is made in the form of a small pipe with a hole inside. The sub produces loud and deep bass. It is often installed in the trunk of a car, but its shape does not always allow this. |
 Closed | It is a closed subwoofer without any holes. It is considered one of the most common types of subs due to the good combination of the quality of the sound produced and the cost of the product. Many motorists know it as a closed box. |
When choosing a sub, you need to focus solely on your preferences and financial capabilities. But you also need to take into account that it is almost impossible to install some types of subwoofers yourself. This should be done by specialists to avoid problems with setting up or installing the device. First of all, we are talking about a bandpass loudspeaker.
Does car body type matter?
Depending on the car interior, the type of subwoofer selected may differ. When tuning a particular body type, the position and volume of the subwoofer may be different.
There are many car body designs, but the most popular include:
- station wagon (Lada Vesta Cross, VAZ 2104, Chevrolet Cruze SW and so on);
- sedan (VAZ 21099, VAZ 2105, Volga 3110, Chevrolet Lacetti, Mazda 6);
- hatchback (Moskvich, 2141, Peugeot 107, VAZ 2108, VAZ 2109 and other models).
When installing a subwoofer in a sedan, you need to make sure that the speaker and port are directed towards the rear seat. It is also recommended to leave a small gap between the seat and the subwoofer (6-8 cm). In some models, an armrest is installed in the rear seat (VAZ 2106, 07). In such cases, it would be better to place the device there. This will eliminate booming and muffled sound.
In hatchback interiors, everything is much simpler - direct the sound direction upward or towards the luggage compartment. This arrangement allows you to get good sound reflection, because the sound will come through the upper parcel shelf, and not through the back of the rear seat.
Manufacturer selection
In order not to waste money, it is advisable to buy a product from a reputable manufacturer. I would like to note right away that it is not recommended to buy subwoofers from Callcell, Mystery and Supra. This is due to the poor quality of the products. Attention should be paid to Prology, Pioneer, Morel, SONY, KENWOOD, BOSS, Alpine and JBL. After purchasing subs from these manufacturers, you will never regret your decision.
Experience all the benefits of the new sound Leading brands are developing new solutions to attract customers. For example, Pioneer recently announced its new creation. We are talking about a special form of subwoofer that easily fits into the spare tire.
Price issue
When choosing even the simplest subwoofer models, you will have to pay from 2000 rubles, but in this case you should not count on particularly high-quality sound. Budget models are only suitable as a first attempt at tuning your car. Over time, you still need to switch to higher quality subs, the cost of which ranges from 6,000 to 22,000 rubles. Devices with a large price tag indicated can be safely classified as professional devices. As a rule, expensive equipment is used more in car sound competitions than on a daily basis.
If you are not an ardent fan of deep bass, then you can safely install an active subwoofer. Even mid-range devices can produce decent sound quality. Otherwise, when the interior of your car does not allow the installation of serious equipment, then in this case you should give preference to passive subwoofers.
