How To Fix Car Stereo Static Noise At High Volume

If you hear any kind of static noise in the background when playing your music from your car stereo through the speakers, it can have a major impact on sound quality. Now everybody describes static differently, in fact some relate static as distortion and some say its a cracking sound from poor signal strength from a radio station. We had a customer come into our car audio shop and mentioned that he had static but he was unable to describe how it sounds. Now this guide has been developed to help eliminate any kind of possibility of static noise at high volumes from your car stereo speakers and help you pinpoint the location.

1) If you a using the aux port on your car stereo, the low bitrate of the mp3 track you are listening to can cause cracking and static at high volumes. Also if you are using a cheap auxiliary cable that can also cause this problem as the soldering joints inside brittle and not strong.

2) If its radio station static you are getting, try a different radio station frequency that is closer to it that might be stronger. Also turn off any electrical types of devices that could interfere with the cars antenna such as your mobile phone or sat nav to see if the static sound goes away.

3) The speakers wire could be shorting. This could possibly be the reason to why you are hearing the static noise as some wires could be touching each other. So remove the headunit from the din slot and your car speakers fitted into the door and rear parcel shelf and check everything fine. The best way to tidy up messy wires is using heatshrink tubing rather than insulation tape.

4) If you have an external amplifier connected to power your door speakers, the RCA cables could be getting leakage from the red power cable. So ensure that both wires are fitted separately down the side panels of your car to possibly avoid this at all costs. Also try a different pair of RCA cables that have better shielding to prevent any noise getting into the car audio system.

5) The ground for both the headunit or connected external amp could be bad, which can create noise to be heard through the car speakers. To ensure that you have clean high quality grounding location, its best to sand down the area to remove any paint to ensure a proper electrical contact with the cars chassis.
