Car audio amplifiers are special devices that are necessary to amplify incoming signals to the required level for their high-quality reproduction. They can be of different types. The devices differ in power and performance. Based on the number of channels, they are divided into monoblocks and multichannel.

Device Description
Consumers most often prefer to buy devices that have 2 or 4 channels. But now you can also find devices on sale that have an odd number of channels, for example, 3 or 5. Single-channel devices are often purchased only to connect a subwoofer to them.
Modern car amplifiers have a huge range of different functions. Most often in devices you can find the following functionality:
- Equalizer. This function is usually present only on expensive devices. Using an equalizer, the user has the opportunity to independently adjust the sound of an audio recording without large losses in the sound quality of the audio track.
- Crossover. This is the name of a special filter that discards unnecessary frequencies. Certain manufacturers equip their devices with crossovers for mid frequencies. This is a useful feature for those who have a car radio installed in their car, since it does not have a built-in crossover.
- Remote control of reproduced bass. With its help, you can adjust the bass, taking into account the sound of a specific composition.
- Fader. This is the signal output regulator. Necessary for balancing the sound level on car speakers.
The latest models often have high-level inputs. This allows you to connect the device to standard audio outputs that come with regular car radios.
Conclusion
If you are just starting your journey in car audio, I would recommend stopping at the Kicx SP 4.80AB, or for a little more money buy a SWAT for growth. This will be enough for you and believe me, the bass and volume will turn out good.
What else do you need
Along with the amplifier, you will have to buy a set of wires - approximately 2 thousand rubles. Because the system needs to be connected to the radio, speaker and subwoofer. If your radio is initially 2-channel, then you will need splitters or so-called games.
The sound level of your audio system also depends on the quality of the radio, but we know from our own experience how not to spend money on it and not spoil the sound with a cheap head unit. Read: how to use an amplifier without a radio.
Recommendations for purchasing the device
When purchasing a device, first of all you need to check with the seller what power the device is endowed with. In this case, you need to know that amplifiers produce two powers - nominal and peak (the amplifier can briefly increase performance indicators).
Most manufacturers often indicate peak power values on packaging to attract customers. Therefore, you must carefully read the technical specifications directly in the instructions that should come with the device.
When choosing a device, experts recommend considering the following criteria:
- Harmonic distortion factor. The maximum allowable value is 1%.
- Frequency range parameter. It is best to choose devices that have a range of 20 Hz - 20 kHz.
- Noise value. This parameter is entered by the device into the played composition during amplification. The noise level must be between 75 and 95 dB.
- The resistance level that the device supports. This parameter must be greater than the input resistance of the vehicle's speakers.
It is not advisable to buy products that have plastic fasteners. The fact is that plastic fasteners fail quite quickly. They won't last long. In addition, in severe frosts, plastic becomes brittle. It can be damaged under the influence of vibrations.
Top Brands for 2022
Before purchasing the chosen model, you should definitely look at the power level, device type, dimensions, build quality and other parameters. High-quality devices should have a sufficiently large radiator, which is designed to remove excess heat. Although there are manufacturers who make thin amplifiers. They are light in weight and do not get very hot, so such designs do not require a radiator.
You also need to look at the name of the manufacturer. Now the best companies producing amplifiers are:
- JBL;
- Pioneer;
- Kicx;
- Sony;
- Alpine;
- Mystery;
- Calcell.
If you need a budget option, you should pay attention to devices manufactured by Power Acoustic and Boschmann. Car amplifiers from these manufacturers are relatively cheap. But at the same time, they managed to establish themselves as worthy models with good components, high-quality assembly and materials.

Purpose and technical parameters
In fact, the amplifier increases not only the volume, but also the sound quality, even with quiet playback. Therefore, the installation of equipment will be useful both for lovers of deafening music and for motorists who prefer a moderate listening mode.
When playing audio tracks at extremely high volumes without using an amplifier, sound distortion is usually observed. This happens due to the discrepancy between the output power of the acoustic system elements and the coefficient of nonlinear distortion. Even the most modern equipment of a car with audio equipment with built-in amplifiers does not give the results that can be obtained by additionally installing a good amplifier. The device's high output power provides increased sound purity and increases the upper volume threshold, which is beyond the control of a standard radio.
Amplifiers differ from each other in many ways. They may have a different number of channels, which are used depending on the connection scheme, that is, the number of connected subwoofers and speakers. Structurally, devices are divided into digital and analog. The former process the digital signal, the latter process the electrical signal. A digital amplifier will allow you to personally select adjustable parameters and remember the frequency characteristics for a specific acoustic speaker.
Devices are selected taking into account the basic parameters, power and frequency range. It is the output power that is the main indicator when choosing which you should take into account the front and rear speakers. For speakers this parameter should be 75 - 100 W, and for a subwoofer 150 - 300 W. The frequency characteristics of the device allow you to adjust the sound of the acoustics according to the characteristics of the car’s interior. They allow you to attenuate frequencies that interact with interior elements, and enhance them when sound is absorbed by interior components.
