Tuning of the auto amplifier – it is a competent tuning of the amplifier that guarantees its quality work. However, if you do not have some knowledge, then it will be quite difficult to tune the device. But if you have at least some experience in working with musical equipment in the car, then the following tips may help you.
Tuning an Auto Amplifier
Sometimes there are moments when you need to improve the sound quality of the audio system installed in your car, or you have purchased a new amplifier. Now you need to understand how to properly connect it to the head unit, find out the best amp settings for bass in car and acoustics and, of course, properly tune it in order to get good sound.
Initial Switching of The Auto Amplifier
After you have turned on the device, immediately need to look at the indicators, which display the state of the amplifier, if the green LED is lit, it means that the circuit is in working order, it means that everything was built correctly and without any errors. In the case where at the time of mains voltage begins to glow red LED, then there is clearly a problem. It is necessary to carefully check the correctness of wiring to the modules, as well as look for the presence or absence of a short circuit in the circuit. It is possible to tune the auto amplifier only when the unit is operating normally at idle with no load.
One of the first settings to be made from the beginning is to set the sensitivity of the sound signal by input with the GAIN control. To do this, you must first turn off the equalizer and LOUD, i.e. the function of listening to music at low volume, and then gradually increase the volume to the peak value, that is when the sound distortions like peculiar rales and noises appear. After that, begin to gradually bring the volume back to a state where the extraneous distorting rales audible to the ear will disappear.
Now, leaving the volume knob at this value, let’s proceed to set the amplifier’s parameters with the GAIN or LEVEL knob. Here we perform the same procedure – find the loudest sound, but without distortion, of the speakers located in the front. We do the same with the sound level of the remaining channels and correct them to the volume of the front speakers.

Tuning in channel-by-channel mode is first carried out with the setting of undistorted sound for tweeters, given that they are the most difficult to withstand the peak signals of the amplifier. The need for a low-pass filter (HPF) for the 65-inch radiators installed in the doors or ovals in the front shelf, again we calculate by ear. Based on theoretical considerations in speaker systems, in which a subwoofer is involved, it is necessary to allow the speakers to work without low bass, without which they better reproduce the signals of the middle frequency, as well as to reduce the cone stroke. As practice shows, in other audio systems, the sound at low frequencies sounds somehow unnatural with HPF turned on. It is quite possible that by turning off the filter the bass will get its inherent density, naturalness, and so on.
As it can be seen from all abovementioned, the technique of connection of the best car amp for the money and its adjustment, unlike a usual amplifier installed in the audio system, is a rather complicated process, which requires certain skills and knowledge. However, if you stick to these tips and follow the instructions attached to the device, everything should work out.
