Many drivers prefer good music in high-quality sound, and this is exactly what the car amplifier is installed for, or even more than one. Sound power and volume are two completely different concepts. 30 Watt tweeters can also play loudly. But at the same time, they will not be able to reproduce properly all the versatility of sound. Therefore, choosing a car amplifier, you must take the device with a margin of power.
So, for example, it is usually written on the receivers that it is possible to connect 4 speakers of 50W each, but it is not noted that this power is given out only for a short time, and at normal times the sound is delivered at 10-20W. Of course, you can create a
car amplifier with your own hands, but will it be so good compared to the original?
These devices can be divided into various categories: mono or stereo. Of course, mono is almost never used, because the second type of system is much more profitable and pleasant for the ear. Although it may contain 4 speakers (usually the receiver has two front and two rear outputs), you can understand the music using the two front ones. This is due to the fact that the stereo itself represents a different sound from two sides, that is, one instrument plays on the one, and the sound of the other is heard on the other. Therefore, if you are not very afraid to upset your passengers sitting in the back seat, then you can limit yourself to only the front speakers.
The car amplifier is also divided by a serial number. It happens 1, 2, 3, 4 and 5-channel.
A two-channel sound amplifier is mostly used to connect either one subwoofer or two speakers. The subwoofer is used to reproduce low frequencies and can be connected in mono mode with two channels. In this way, power boosting is achieved. But it is worth noting that for the proper operation of the device, a low-pass filter is required, which must be built into the car amplifier, while on other equipment for reproducing sound, low frequencies are generally removed.
Four-channel amplifiers occupy a leading position among motorists. They are the most versatile devices. If you think about how to connect a car amplifier of this type, then you can choose different options. Some use a subwoofer and front speakers, while the channels are divided in half. Others only connect speakers (front and rear). But there is the possibility of "strip" separation, that is, 2 inputs go to the "tweeters", and the other two - to H4.
Five-channel devices of this type, in fact, are no different from the previous ones, only instead of two channels going to the front speakers, there are 4, you can connect them both front and rear. Band use is also provided if the filters meet the requirements.
After the amplifier is selected, it remains to connect it, and this is a rather difficult task. It is worth remembering that it must be ventilated, since the device has the property of heating. Also, the entire structure, including wires, must be securely fixed.
