I have two amps, alpine for my highs and punch for my subs. The remote wire for my subs causes high pitch but low sound. Does not go up and down with the volume or engine, just constant. If I put pressure on it, it goes away. Then comes back after a few days until I wiggle it again. Can my remote wire be causing the noise or from something else making it do that? You cannot hear it with volume 1/4 turned up. But I know its there.
