[QUOTE="Zenn, post: 3992095, member: 15503"] that noise is caused by bad grounding, unfortunately it can be many things, coz all wires got ground. can be loose rca cable (the signal cable from your player to your amp), or bad grounding on the amp ( not the one in your engine) re-do the ground to make sure its contact with bare chasis metal, no paint. sometimes wire route can also cause this noise, if power wire and signal wire/speaker wire are too close together or speaker wire/speaker wire/passive crossover are near the car's ecu certain aftermarket spark plug cable also can give this noise [/QUOTE]
