Issue with my amp, think its a bad ground

Featured Replies

Hi guys, I'm going to post this in the ICE forum as we'll but I have an issue with my amp and speakers where you can hear the engine noise and steering through the speakers, I have tried using a ground loop isolator and all that seems to do is make my music quieter, it slightly recuses the engine noise but make the music quieter, I also have used ferrite on my head unit wires to try to get rid of the problem as well, I have also moved the grounding point to various points on the rear of the car but still no joy, any one have any ideas?

I had this problem a long time ago in my Clio. I found that my power lead was too close to the RCA cables or Speaker cables on that occasion. Could that be it?

Run your power cables down on side of the car and the RCA down the other side, my mate has this issue in his Supra and moving the power cables solved the issue.

Fixed it today, don't know how we managed it but me and my dad stopped my interior run the speaker and RCA cable down the center of the car by the handbrake and the power on the left side tucked away, fitted my ground loop isolator to the amp and it is all good now, I now enjoy my music. Only issue being now is having my car in parts I'm now carbon wrapping anything I can get my hands on time to spend more money
