Car amplifiers help in producing the best sound from the audio system in the car.

When you buy a car amp and install it without getting the desired audio quality, you might think that you have been swindled. However, the issue here is pretty simple and it’s mostly because you do not know how to adjust the amp for good sound.

This article will enlighten you on how to adjust vehicle amp for the best sound whenever you acquire a new vehicle amp. The process is not as difficult as you assume, so relax and read the steps you need to adjust your vehicle amplifier for enhanced audio.

Switch off everything in the vehicle amplifier and disconnect all the wires connected to the vehicle amp especially the RCA wires. After this, switch on the stereo system.

At this time, if there is no sound coming from the vehicle amp, you can increase the volume of the stereo to the highest point. Please note down the figure showing on the head unit.  

At this point, you should be aware of the highest volume of your amp, lower it to 80%, and set the stereo’s equalizer settings to “Flat”. In the amplifier, set the Gain and Bass Boost to zero, and place the crossover filters to full.

Put all the RCA cables into the speaker slots that you want to adjust. You can now turn on the music you want to listen to and gradually turn up the gain until you hear distortion in the speakers.

Peradventure you hear distortion, you can reduce the gain control until you don’t hear it anymore distortion. You will make the current base gain the point of placing all your frequencies at the vehicle amp.

This will produce nice tunes that you will enjoy anytime you are driving your vehicle.

The next step is to turn on the crossovers and filters back after the base gain settings. When adjusting sub-woofers, you can select the low-pass filter (LPF) and utilize the high-pass filter (HPF) for remaining speakers.

However, when you don’t have subwoofers in your system you can ignore this process and allow crossover and the high-pass filter to be in full. When you are changing the sub-woofers, find out its highest rating and ensure that the frequency dial tally with it.

Also, when you are changing the speaker system, check the lowest frequency rating and ensure that the frequency setting matches the rating.

If the stereo volume is very high and you need to reduce it because you are not a fan of loud music, all you have to do is to reduce the bass boost setting of your vehicle amp.

To achieve this without any distortion on the speakers, you need to adjust the bass boost and the gain simultaneously until the desired audio is achieved.

After setting up the frequencies and bass boost, check the gain of your radio and increase the loudness to 80.

You can put back the vehicle amps when you are adjusting the amps differently and reduce the stereo’s volume to the lowest point.

Additionally, you can increase the sound to 80% if there’s no distortion and all adjustments are done properly.

In case you still hear any distortion from the speakers while carrying out these tests, you have to identify the speaker that it is coming from and reduce the volume until you fix it.

Finally, the maximum volume of the stereo should not go beyond 80% as sustained maximum volume arrangement will cause wear and tear to the speakers and may also cause damage to the eardrums.

Due to the fact that different genres of music require different amplifier settings, you need to find the right setting and adjust the vehicle amps accordingly to avoid distortion.

Operationalization of Vehicle Amps lexicons

If you are reading about how to adjust vehicle amps, there are some words you will come across which might hinder your understanding of this article. So, it is wise for you to be acquainted with these words. I decided to break these words down so that you can comprehend this article.

Some of these words include:


It is the part of the amps that helps in regulating the sensitivity of the vehicle amps. What this means is that it controls the energy emanating from the vehicle amps to the required amount, so that the speakers will be able to control the energy.

Put in other words, the gain is that part of the vehicle amps that you use to turn down the distortion coming from the speakers.

Frequency: it is a field that houses the audio that comes from the speakers. Knowing the frequency of your speakers is not a difficult task as they are conspicuously indicated at the front of the speakers.

In case the frequency is not indicated there, you should check the rear of each of the speakers.

These frequency figures are very important due to the fact they are required to change the amplifier adequately.

Low-pass/High-pass Filters

They are permanent features of the frequency which when it is on either the highest or the lowest frequencies travel across the output jacks.

When you have limited speakers in your vehicle, for you to control high frequencies, you have to on the HPF at the linked receiving end.

Furthermore, when you have average speakers on your vehicle, adjust the filters to full which makes the receiving ends to produce different kinds of frequencies. 

Top-quality vehicle amps in the market     

Your audio system will not produce a good sound even after an upgrade if it is not a top-quality amp.

You have to get the finest amplifiers in the market if you want to get the soothing audio pleasure you desire from the car.

Mono: it energizes a subwoofer.

With this kind of channel, your speakers will be on however, they will not have any more energy from the vehicle amps in your vehicle.

2-channel: this kind of channel is most appropriate used to energize subwoofer and two speakers.

4-channel: it is appropriate for energizing your sub and also double speakers.

However, you might intend to energize other speakers at a later date, you have to lessen the vehicle amps in order for it to energize a sub and two speakers.

The improved version can be installed later.

Impedance: impedance is a very essential factor to consider when selecting the vehicle amp to put the subs or the speakers.

When you want to change the inbuilt unit, endeavor to locate a sub that contains a speakers-level insert.
