I am installing my radio/amp and I get a horrible noise through my amp and subs when I turn the amp on. The regular speakers (not running through the amp have no noise at all) just the amped speakers. I narrowed it down to my electronic fuel pump that is causeing the feedback. When I pull the fuse to the Fuel Pump the noise stops and it sounds great! Is there something I can do or some way to rewire the pump so it is not messing with my amp? Maybe bigger gauge wire would cut down on the feed back? Maybe a better ground or multiple grounds? The noise is very bothersome and I have to fix it before I go nuts!!! Anyway, I just rewired the whole truck and the noise did not go away (but then again I did not change the rout of the wire either)..
