How to choose an amplifier for car speakers
Car owners pay great attention to the acoustic equipment that is installed in their personal vehicles. Some audiophile drivers cannot imagine a car without an amplifier, speakers and a subwoofer. Tuning a prestigious car requires the installation of just such additional audio equipment. How to choose it correctly?

Why do you need a sound amplifier for your car?
Passenger car manufacturers equip 80% of their vehicles with acoustic systems. They try to make the sound quality comfortable for the car user.
At the same time, not every driver will agree to use factory equipment, since a stationary radio does not always satisfy the individual requirements of the car owner.
Using an amplifier in a car allows you to:
- improve sound quality;
- increase volume;
- expand the range of reproduced waves;
- adjust and remember the sound frequency settings, depending on the driver’s wishes.
IMPORTANT! The software of modern equipment allows you to fix the parameters of the sound signal adjustments. This is convenient when listening to different music, as well as when changing listeners.
Installing a powerful amplifier, with the corresponding accessories, is part of the stylish tuning necessary for drivers who want to emphasize their driving style and commitment to a particular musical direction.
Characteristics of amplifiers for car speakers
When choosing equipment for a car, the driver takes into account his own wishes: how loud the sound should be, the signal quality in terms of frequencies and the availability of standard or additional installation space.
These parameters are displayed in the technical characteristics of the amplifiers, which are divided into:
- by number of channels;
- class;
- signal strength;
- minimum and maximum frequency;
- the presence of a filter and adjustment of ultra-low vibrations;
- harmonic distortion coefficient.
Channels are equipment outputs to which one or more speakers are connected. Single-channel technology is used when connecting a subwoofer. Limiting high frequencies in such an amplifier does not matter, and the low “bass” filter and its adjustment are welcome, especially in the absence of such correction on the car radio.
Two or four channel equipment is used to listen to stereo and quad systems with the appropriate number of speakers. Using the bridge connection method, 4, 6 or more speakers are connected through two-channel equipment. Installation of stereo speakers with a subwoofer is carried out through a three-channel amplifier.
The class of amplifying equipment is indicated by letters of the Latin alphabet. Despite the large number of models produced, it is better to choose a device belonging to class AB or D. Class AB amplifiers have lower efficiency than Class D amplifiers. This allows the latter to produce more power with smaller dimensions, although this is reflected in the cost.
There are rated and maximum power of radio equipment. At nominal, the equipment will work for 2-3 hours, and will be ready to continue playing music.Maximum is the output characteristic that the amplifier will produce in a short period of time.
When purchasing, pay attention to the nominal value. Operation at high volume will distort the sound and have a detrimental effect on the operation of radio equipment, if we take the calculated maximum power value.
The ability to select frequencies characteristic of a particular model depends on the wishes of the driver, who wants to hear lower or, conversely, higher sound tones.
REFERENCE! Researchers have identified a difference in perception that is characteristic of 90% of the population: men like low tones, and women like high frequencies.
What to consider when choosing an audio amplifier for car speakers
The main criteria when installing audio equipment in a car are signal strength, the number of channels corresponding to the speakers and sound quality.
IMPORTANT! The amplifier power should be greater than that of the speakers. Failure to comply with this condition will lead to a decrease in sound quality as the volume increases.
The frequency range of the output channels must also correspond to the technical parameters of the speakers. In addition to the listed characteristics, special attention is paid to input sensitivity.
The presence of adjustment of the input signal allows you to use the amplifier on different cars. In the absence of such adjustment, you should make sure that the parameters of the output signal of the audio recorder correspond to the sensitivity parameters of the connected equipment.
Fans of “bass” should pay attention to the presence of a low-pass filter, which removes vibrations harmful to humans and radio equipment - less than 20 Hz. The presence of adjustment of the level of such frequencies will allow you to comfortably use the amplifier and speakers in different situations. For music lovers who pay great attention to sound quality, it is advisable to take into account the distortion factor, which should not exceed 1%.
Having made the right choice of amplifier for the car, each driver can go on a long journey and enjoy listening to their favorite audio recordings.
