[QUOTE="dan45hk, post: 5841541, member: 570846"] I'm having some problems... there is really bad alternator whine which gets worse with revving. The car is a '94 Vette and has 0 gauge power and ground wire coming directly from the battery to the amps in the back (Zapco 1000.4 for highs, JL 1000v2 for sub). The alternator whine problem has me stumped as everything in the system is hooked to a 0 gauge wire coming from the battery negative. I don't see how this can cause a ground loop as there is only one grounding point. Any suggestions? I dont get any whine with just the sub amp (JL 1000v2) hooked up, but it starts when the Zapco is hooked up (but I guess you can't hear whine through a sub or can you?). 1994 Avic Z1 Head unit Zapco 1000.4 to Rainbow Germaniums front and rear (Symbilink) JL 1000v2 to 12W7 (RCA) [/QUOTE]
