9 Ways to Solve Your Car Speaker Distortion At Low And High Volume

Having the finest music in your car is one of the greatest achievements that can make your ride comfortable. You will find that most people make some simple mistakes that result in distortion of speakers when in high volume and sometimes in low volume. Others may install complex sound systems which cost them a lot but still fail to achieve the fine and clear output. This may be as a result of many issues in your system and the car itself but here, we will discuss some of the ways you can implement to solve your car speaker distortion at low and high volume.

Use High Pass Filters

It is advisable that you include high pass filters on the front and rear speakers when installing a sound system in your car. The filters work better when the volume is both at high or low by regulating the bass that goes to the door speakers causing the distortion. Note that most of the car doors are not designed for bass. This is because the door inside has the small cone shape thus tending to distort faster. Therefore, switching on the HPF blocks bass and volume frequencies beyond 80Hz thus minimizing distortion resulting to clear sound output.

Reduce the Bass at High Volume and Increase at Low Volume

If you find that there is distortion despite the efforts of minimizing distortion of your car speakers, you can reduce the bass at the controls. +10 bass and around -5 treble offers very clear sound at low volume but distortion will become real at high volume. This produces an unpleasant sound that you prefer shutting down the whole system and have a silent boring drive. You can achieve clear sound quality by reducing the volume at the audio settings. You need to leave the fronts and the rears for pure vocals and install a new subwoofer at the back of your car for the bass. This gives you time to understand your system and eventually notice the problem where you can rectify and achieve clear sound without distortion.

Avoid Bass Boosted Music

Bass boosted music is out there and cheap. It is usually produced professionally using the software. This music will distort the car speakers at low and high volumes. Imagine if you have an amplifier, this bass boosted music will tend to produce extra bass that causes distortion no matter how good is your system. This music tends to cause frequent distortion thus reducing the strength of the speakers, therefore, it is better to use music from originals CDs.

Use an Equalizer or Signal Processors

The car interior is not made for the perfect sound unless you customize. Plastic and glass surfaces reflect the sound while carpet and seat covers absorb the sound not mentioning poorly placed and fitted speakers. The mix results in poor sound quality in high volume. To rectify the issue, you need to install equalizers that usually feature more than 13 bands of equalization where its level enables you to match maximum voltage.

Usually, common car receivers offer treble, mid-range, and bass controls that address the global fixes but not the actual problem. This is why you need an equalizer to zero in and kill the peaks. You can have it mounted on your receiver or on the dashboard. The outboard equalizer enables you to adjust frequency response depending on low or high volume. You can also include a parametric equalizer to vary the center point and the width enabled by each EQ band to completely zero in the distortion and also a sound processor the enable you to reduce the frequency response peaks and enable the speakers to increase the bass response.

Using Car Amplifier

Most people do not understand that there is a huge disparity between the output of a factory car stereo and that of an amplifier. An outboard amplifier provides more clean power and sound output than any car stereo as it is made to filter the sound and amplify the finest sound output. The amplifier is made to produce the finest sound and for the best output. You can adjust the stereo volume to the lowest and increase the amplifier volume and you realize that the amplifier releases the finest sound output you have never achieved before that causes no distortion to the speakers.

Using a Crossover

Modern receivers include frequency filters that work well with preamp speakers thus minimizing distortion on low and high volume. For the subwoofer, you need to use High Pass Filters which removes the distortion and low bass. This enables your system to gain a clear and clean sound where you can also try lowering the crossover point for the low pass filters that bring the bass up and forward thus achieving the maximum pure sound.

Setting up Your amp Gains

People usually think that gain controls adjust the volume level thus turning the volume up high only to get much-distorted sounds from the speakers. The truth is that gain controls enable you to adjust the input signal coming into the amplifier. If you tune it so high, then you only encourage nasty distortion. The best way is to set the receiver’s volume halfway or three quarter and adjust the amp gain until you hear no distortion. The amplifier always offers clear sound at low volume and high volume without distortion from the car speakers.

Always Use High-quality Music Files

Compressed music usually loose high and low-frequency music. If you want to store music on your music player, then you should make sure you use quality compressors. Your car sound system can detect poor files as you can clearly get the distortion produced in both low and high volume especially if you have an amplifier that amplifies every single detail in the music files. To minimize this distortion, you need to get used to the high-quality music.

Replace Your Car Speakers

After using your speakers from the manufacturer for a long time, and you realize that the frequency of distortion is high even on a new system, then it means that the speaker is wearing out and losing its power. You can always replace with aftermarket speakers that have a compatible power range with your amplifier.


To obtain maximum clear sound output without distortion from your car stereo at low and high volume, you have to understand the basics so that you can be able to adjust the controls. Sometimes the problem is just from the controls, understand the power of your system and you can be able to control the sound to the finest. You can also use sound deadening materials such as Dynamat to reduce vibration and the noise thus providing a suitable environment for the speakers to output clear sound without distortion.
