[QUOTE="jacko, post: 809960, member: 559993"] take your RCA's off the zapco. If you drive around with everything connected/on except the zapco RCA's, and you still here noise thru the speaks, then it's an amp grounding prob. If their is no noise thru the speaks, then the noise is brought in thru either the deck or the RCA's. Make sure your RCA's are at least 12" from your power wire, if this is not possiable and you don't have good RCA's with a ground thru them, just wrap a 16ga wire (about 15 feet of wire for a 10 foot RCA to give u an idea) and ground one end of that wire. Do that for the power if that doesn't work. If not it's the deck. Try a new one or try giving the deck it's own ground. But then again, Pioneers are known for having bad ground planes in them for the RCA's, mine did :-). However if you'd like to further isolate it to the deck/RCA's, take a portable cd player and hook it up right to the amps(make sure it either has a line out and you know the output voltage, or you just make sure you don't make the amps clip) oh well. Also you said it doesn't do it in your subs, try switching the sub/speak RCA's to check for bad RCA's. I hope this helps. [/QUOTE]
