Pioneer Premier Deh-P700R, static?

[flatlandin_man2 10+ year member]

Ok, i have had my pioneer premier head unit for only like 5 months. It has 3 sets of preamp outputs(front/rear/sub). I have been hearing like a humming noise through my speakers on my sub output. When i got on the gas it would get louder. But, when i hooked it into my front output, the noises stopped. If i hooked it into my rear outputs though, i could still hear it. Is this a problem with my headunit, or is it a problem with my wiring? I heard something about not runnig your RCA cables near your power wires or it will make this sound , is that true?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

check your ground and make sure its clean. Also confirm that you have a clean power supply. If the noise is increasing when you accelerate my guess is its alternator noise.

Find out where you are pulling the power to your HU. I had some morons wire my changer once into the console power line and it whined like a bastard. Changed its power source and problem disappeared.
