New System Install Problems

[dan45hk 10+ year member]

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?).

pioneer ground loop issue I think.

Is there any way to check if it is the Pioneer or a way to fix it?

Just checked something else, I unplugged everything from the head unit and only left the 2 Symbilink cables, with the car off and the headunit and Zapco amp on I get the whine which gets worse when you turn up the gains on the amp. Does this still point to the Pioneer as the problem?

Nevermind guys the amp died, looks like Woofersetc screwed me again with this "new" amp.
