Long gone are the days when, when you sit in the car’s interior, you have to prepare for hours to listen to the mournful noise of the engine or the crackling noise of the radio. Modern cars are equipped with stereo systems, which in terms of richness of acoustic effects can compete with concert halls. “Amplifiers” are connected to them so powerful that you can find out about the approach of a machine long before it appears in sight.
Talk about amplifiers
Any driver who decides to equip his interior with high-quality stereo equipment is seriously thinking about which sound amplifier is better and which model is suitable for its audio system. What should I look for in resolving the issue?
- Dimensions. The driver must understand exactly where he will place his sound amplifier, and he must choose the technique based on the given parameters. Otherwise, an unpleasant situation may arise when the device is purchased, and there is simply nowhere to place it. Those. the first rule is the harmony between the dimensions of free space in the cabin and the dimensions of the amplifier.
- Device class. The classification begins, as usual, with the letter A:
- Class A. The sound amplifier related to it is not very suitable for its functional role. Devices of this type are characterized by low-frequency distortion, a weak sound, as a result of which, in order to hear music when the engine is at full speed, the volume has to be set to almost maximum. In addition, this sound amplifier heats up quickly due to high energy consumption. This does not add vitality to the device itself or to the machine battery.
- Class B devices. They are much better than the previous one in technical parameters, sound transmission quality and thermal stability.
- AB class. The sound power amplifier related to it is an average device between classes A and B in terms of parameters. Most often, they are found in cars and their wide selection is presented in the electrical market.
- Class D, in another way - digital signal amplification. Previously, devices operating at low frequencies were characterized this way . At present, this is the designation for a broadband car sound amplifier . True, the quality of his work is somewhat inferior to the previous one. Therefore, today it is the AB class that is more prevalent than others.
Channels to connect
Modern car audio systems are quite complex. If a couple of dozen years ago, the driver mounted only two speakers in the cabin, then the current "stereo centers" may well compete with sophisticated home theaters. Today, manufacturers produce amplifiers with channels from one to six. A two-channel device is considered traditional as the number of CDs recorded on standard disks. What are the most common connection schemes?
- “Rear / Front”. Amplifier for 4 channels, the sound type is “surround”. Less circuitry - the main wealth of sound remains in the background, and for low frequencies a subwoofer is needed.
- "Amplifier" with the scheme "front and subwoofer." Such are widespread among motorists. Easy to operate, standard in terms of quality parameters. The sound is reproduced quite nicely. Channels from 3 to 4 or a "bridge" connecting two into one channel.
- Multimedia scheme for a movie theater in the car.
The most suitable option is an amplifier with two channels, if installation allows. More economical in terms of money options when the amplifier has 4 channels or 6.
