Настоящие меломаны всегда стремятся получать качественный звук от аудиосистем. Однако, производители автомобилей часто экономят на установке мощной мультимедийной аппаратуры. Поэтому приходится задумываться о том, how to choose a subwoofer and amplifier in the car самостоятельно.

With their help, it is possible to adjust the harmonious sound of audio files at different frequencies, especially when playing deep bass. For almost all regular speakers, sound quality parameters are an unattainable luxury.

Choosing the right sound

It is necessary to take into account that the low-frequency element in the form of a subwoofer, unlike the other speakers, is not an independent unit through which the sound is reproduced. It only complements the overall system, and without the support of standard speakers will not produce an adequate result.

It is believed that choosing which subwoofer to put in the car, you need to focus on its value. After all, buying acoustics of this type is more expensive than for 20% of the cost of the car itself, it is not recommended. But an overly cheap subwoofer will be a waste of money without giving out high-quality sound.

When searching for a decent machine, you need to know that There are two types of subwoofers:

• active;
• passive.

The design of the active subwoofer is characterized by the presence of a built-in amplifiertherefore, he does not need an external supplement. The device has a high reliability, which is achieved by the design features. The advantage is that to connect it, manufacturers often provide standard connectors. It is easier and faster mounted and configured.

Подбирая, which subwoofer is better in the car: active or passive, стоит упомянуть о недостатках активной компоновки. Предлагаемый аппарат имеет законченную цельную конструкцию, которая не всегда способна аккуратно вписаться в габариты салона. Считается, что бюджетные модели данного типа имеют худший звук за счет экономии производителями на корпусных материалах.

Passive subwoofer circuit

When buying a passive subwoofer motorist receives only one subwoofer. To him you need to purchase separately high-quality amplifying equipment. You will also need a set of cables and connectors.

Each driver will be able to install both independently and using the help of professionals. They will more organically fit the kit into the limited space of the car. All sound adjustments after installation of the equipment are carried out through the connected additional amplifier.

Amplifier selection

The presence of the amplifier in the car will give the sound greater breadth and volume. Even despite the basic audio system, the amp is able to pull the average sound to a new quality level.

Due to the use of a larger frequency range and advanced settings, the music lover will be able to correctly distribute the flow between the existing built-in speakers. Although standard systems are often labeled 4x50, they are sometimes unable to drown out the hum of the road, which can be heard with poor sound insulation. In most regular audio power is limited to 10 ... 12 watts. Only an additional amplifier is capable of raising this limit.

Amplifier Subwoofer

The devices are differentiated by the number of channels, which can be from 1 to 6. Also, they are analog and digital. In the first case, a higher efficiency, but less power. In the second case, the power is higher, but the quality is slightly lagging.

The most popular are the five-channel devices. These include

• Genesis Profile Five;
• Alpine PDX-V9;
• Audison SR 5;
• DLS MA51;
• Blaupunkt GTA-5350;
• Rockford Fosgate R600X5.

Four channels of speakers can be easily connected to them and the fifth one will be low-frequency.

Diversity of subwoofers

Differences in subwoofers are on the layout. It is customary to allocate open and closed units.

For open models, it is customary to use the installation in the auto panel, since the bass is not enclosed in a rigid frame of the case. The frequency is adjusted only by the low-pass filter, however, this design will not provide a level below 100 hertz. In most cases, these devices are put novice drivers.

As closed structures, columns enclosed in rigid frames are common. They are divided into three types:

• Sealed - when the module has a closed case. Advantages consist in simplicity of a design and lack of an overload of the loudspeaker. The disadvantage is extremely low efficiency.
• Filters possess tunnels in the housing. Due to such a constructional find it is possible to reduce the pressure on the diffuser. Also, the tunnel significantly increases the efficiency of the device.
• Bandpass consists of elements of the two previous designs. He is also called a strip sub. It has a built-in tunnel divided by a grid into two compartments. Due to this, in the rear part of the module, a closed space is formed, which increases the diffuser stiffness. The front part is open with the output through the phase inverter. Sub has large dimensions in comparison with analogues.

For the latter type, it is necessary to carry out installation only in the factory case.

The main parameters of subwoofers

Choosing which active subwoofer is better to buy into the car, you should focus on its basic characteristics. The nominal values ​​for different models are significantly different and not in all cases depend on the cost.

For active saba it is important to select a higher power rating. Be aware that a higher overload threshold will give a cleaner bass. When choosing passive devices it is necessary to take into account the capabilities of the built-in amplifier.

Audio speakers with an output of, for example, 0.9 kW or 0.45 kW are capable of producing comparable sound pressure, but between them there will be a significant difference in sensitivity. In any specialized store, you can consult with an experienced seller about what real power give speakers.

An important parameter is coil resistance. A common parameter is 4 ohms, an eight-ohm coil can be rarely found, and the load of two-ohms is not enough for your modern sub. It is desirable that there are at least two coils to ensure high-quality connection of devices.

Popular manufacturers

Acoustic products are manufactured for consumers with different incomes. The cost of subwoofers depends on both the manufacturer and the output parameters of the equipment. When buying, it is necessary to install products on the warranty, so that there is an opportunity to change it in case of any problems. To do this, you need to buy a subwoofer at licensed points of sale.

The most popular among domestic avtomelomanov enjoy the company:

• ALPINE;
• MYSTERY;
• Pioneer;
• PROLOGY.

The most budgetary options for low-frequency acoustics can be found at a price of 2 thousand rubles, but you should not expect a decent sound from them. You can look at the following current models:

• PROLOGY WOWBOX1200 (about 3,500 rubles);
• PROLOGY WOWBOX1000 (about 2,700 rubles);
• DRAGSTER DER210 (about 4300 rub.)

More expensive category of subs:

• CADENCE MBX-12A (8000 rubles);
• CADENCE XBP-122 (11,000 rubles);
• ESX SXB-302 (12500 rub.).

Some music lovers will not stop the price of several tens of thousands, for example, for AUDISON TH10 (more than 65,000 rubles.).
