Gone are the days when, sitting in a car, you have to prepare for hours to listen to the mournful noise of the engine or the crackle of radio interference. Modern cars are equipped with stereo systems, which in terms of the richness of acoustic effects can compete with concert halls. The “amplifiers” connected to them are so powerful that you can find out about the approach of the car long before it appears in the visibility zone.
Let's talk about amps
Any driver who decides to equip his cabin with high-quality stereo equipment thinks seriously about which sound amplifier is better and which model is suitable for his audio system. What should I pay attention to in resolving the issue?
- Dimensions. The driver must understand exactly where exactly 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 fit it. Those. the first rule is harmony between the size of free space in the cabin and the dimensions of the amplifier.
- Device class. Classification begins, as usual, with the letter A:
- Class A. Related to itthe sound amplifier does not fit well with 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 running at full speed, the volume has to be set almost to the maximum. In addition, this audio amplifier heats up quickly due to the high power consumption. This does not add viability to either the device itself or the car battery.
- Class B devices. They are much better than the previous one in technical parameters, sound transmission quality and thermal stability.
- AB class. The audio 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 on the electrical engineering market.
- Class D, in other words - digital signal amplification. Previously, devices operating at low frequencies were characterized in this way. At present, this is the designation of a broadband car audio amplifier. True, the quality of its work is somewhat inferior to the previous one. Therefore, today it is the AB class that is more common than others.
Connection channels
Modern car audio systems are quite complex. If a couple of decades ago, the driver mounted only two speakers in the cabin, then the current “stereo centers” may well compete with fancy home theaters. Today, manufacturers produce amplifiers with channels from oneup to six. A two-channel device is considered traditional - by the number of CDs recorded on standard discs. What are the most common connection schemes?
- Back/Front. Amplifier for 4 channels, sound type - "surround". The minus of the circuit is that the main richness of the sound remains in the background, and a subwoofer is needed for low frequencies.
- "Amplifier" with a "front and subwoofer" scheme. These are widely distributed 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 in-car cinema.
The most suitable option is an amplifier with two channels, if the installation allows it. More economical options when the amplifier has 4 channels or 6.
