i just hooked up my amp but now i am getting a high pitch noise out of my subs when the engine is running or the key is turned on. if i turn the key to acc it doesnt make the noise. Is there any way to fix it?
^^ jsut like they said... try n check for a ground problem, sounds like you have a ground whine/loop. search for "ground loop fixes" threads here and some of the things there can help you out.
