[QUOTE="Prowler573, post: 2814521, member: 561023"] quaker is right on the money here. The noise filters and ground loop isolators are nothing more than a band-aid to cover the problem rather than a cure to eliminate it. Alternator whine is almost [I]always[/I] indicative of a poor ground somewhere in the signal path. It is up to you to troubleshoot just where in the path that bad ground connection is and then remedy it. Could be a bad ground on the HU. Could be a bad set (or sets) of interconnects allowing induced noise into the signal. Could be a poor ground on the amp. It [I]could[/I] be all of the afore-mentioned problems. Find it. Fix it. Done.
