[QUOTE="Danny Marz, post: 8674790, member: 676954"] Ok so I had a bad alternator whine when I grounded my amp thru the floor directly to the frame. Yes I hit the frame with sandpaper and a wire brush and had a clean metal ground. Then I tried grounding directly to the battery and the whine is basically gone. Does anybody know why this is?? I’m just keeping it grounded to the battery for now as it sounds 100x better [/QUOTE]
