[QUOTE="bumpasauras, post: 8281948, member: 607820"] ^^^^^^ This. I bet it's a hu issue bypass the hu like Mylowes suggested if it stops go get ya an aftermarket deck if it's still there then maybe an alt issue.. The thing that sticks out to me is the noise quits when the car is on batt power... That almost always tells me it's a charging issue or a grounding problem but if you have gone over all the grounds and then some than we will look deeper. Well first things first bypass the deck if the problem persists try removing the charge wire that goes from alt to bat by pulling off the positive while the car is running (car should still run)and c if that kills the noise if it does than there is possibly an alt problem (have it checked at a parts store) If the hu bypass does not remedy the prob, and with the charge wire from the alt to the batt disconnected if the noise is still there with the car running then you pretty much know it's not the alt or hu unless u have a short somewhere .. But I bet one of the 2 actions will kill the noise and at least point u in the right direction Good luck Bet it's the hu [/QUOTE]
