Car owners pay great attention to the acoustic equipment, which is installed in personal vehicles. Some music lovers do not represent a car without an amplifier, speakers or subwoofer. Tuning prestigious cars requires the installation of just such additional audio equipment. How to choose it correctly?
Why do I need a sound amplifier in the car
Car manufacturers equip 80% of the produced vehicles with an acoustic system. They try to make the sound quality comfortable for the user.
In this case, not every driver agrees to use the factory equipment, since a stationary radio tape recorder does not always satisfy the individual requirements of the owner of the car.
The use of the amplifier in the car allows you to:
- improve sound quality;
- increase the volume;
- expand the range of reproducible waves;
- adjust and remember the settings of the frequency of the sound, depending on the wishes of the driver.
IMPORTANT! The software of modern equipment allows fixing the parameters of the sound signal adjustments. This is useful when listening to different music, as well as when changing listeners.
Installing a powerful amplifier, with the appropriate accessories for it, is part of the stylish tuning required for drivers eager to emphasize driving style and commitment to a particular musical direction.
Characteristics of amplifiers for speakers in cars
When choosing equipment for the car, the driver takes into account his own wishes: how much loud the sound should be, the quality of the signal at frequencies and the availability of regular or additional installation space.
These parameters are displayed in the technical specifications of amplifiers that divide:
- by the number of channels;
- class;
- signal strength;
- minimum and maximum frequency;
- the presence of a filter and adjustment of ultra-low vibrations;
- harmonic distortion.
Channels are equipment outputs to which one or more speakers are connected. Single-channel technology is used when connecting a subwoofer. The limitation of high frequencies in such an amplifier does not matter, and the low-bass filter and their adjustment are welcome, especially if there is no such correction on the car stereo.
Two or four channel technology is used to listen to stereo and quad systems with the appropriate number of speakers. Using the bridge connection method, 4, 6 and more speakers are connected via two-channel equipment. The installation of stereo speakers with subwoofer is carried out through a three-channel amplifier.
Classification amplifying equipment denoted by the letters of the Latin alphabet. Despite the large number of models produced, choose a better device belonging to the class AB or D. Class AB amplifiers have lower efficiency than the D-class. This allows the latter to produce more power, with smaller dimensions, although this is reflected in the cost.
There are nominal and maximum power radio. At the nominal, the equipment will work for 2-3 hours, and will be ready to continue playing music. Maximum - this is such an output characteristic that the amplifier will issue in a short period of time.
When buying, pay attention to the nominal rate. Operation at high volume, will distort the sound and adversely affect the operation of radio equipment, if taken for the calculated - the maximum amount of power.
The choice of frequencies characteristic of a particular model depends on the wishes of the driver who wants to hear lower or vice versa - high timbres of sound.
REFERENCE! Researchers have identified the difference in perception characteristic of 90% of the population: men like low timbres, and women like high frequencies.
What to consider when choosing a sound amplifier for car speakers
The main criteria for installing audio equipment in a car are the signal power, the number of channels corresponding to the speakers and the sound quality.
IMPORTANT! The power of the amplifier should be greater than that of the speakers. Failure to comply with this condition will lead to a decrease in sound quality, with an increase in volume.
The frequency range of the output channels must also comply with the technical parameters of the speakers. In addition to the listed characteristics, special attention is paid to the sensitivity at the input.
The presence of adjustment of the input signal allows you to use the amplifier on different cars. In the absence of such an adjustment, make sure that the parameters of the output signal of the audio recorder are consistent with the sensitivity parameters of the connected equipment.
Fans of "bass" should pay attention to the presence of a low-pass filter that removes vibrations harmful to humans and radio equipment - less than 20 Hz. The presence of adjusting the level of such frequencies will allow you to comfortably use the amplifier and speakers in different situations. Music lovers who pay great attention to sound quality, it is desirable to take into account the distortion factor, which should not exceed 1%.
Having made the right choice of the amplifier for the car, each of the drivers can go on a long journey and enjoy listening to your favorite audio recordings.
