Hmm. These grounding probs are a poo aren't they?

I had bad a ground loop until I found that my crossover was the source of most of it. I took it out and SHAZAM. it was gone! So it may not be just the amps or the empeg.

do you get whining when you use a source separate to the car, ie. plug the empeg into the AC mains and power up the amps. still whining? then it's within the amp setup. otherwise it may be the supply rail of the head unit (empeg or not).

try just connecting the center pin of the audio cables into the amp. this either gets really good or [u]really[/u] bad. If it gets better it is definitely the grounding issue, if worse there may be a problem with the power supply rail to amps or head unit, either alternator noise or still a loop problem.

also try moving all amps & head unit to one spot, hooking them all up with power and what does it sound like?
The power cable from the battery goes thru the firewall, branches off to the front amp and on to the amp in the back. Have you taken the emepg power from here too? might be worth a try.
do you take ALL your ground cable back to the same point? need that too but preferably with short cables.

Are the amps indirect contact with metal?

how am I going Dominic?

We'll all band together so that ClemsonJeep can impress his date tonight he said stoicly to no one inparticular
