Alright. Let me know what you find. I was asking about the whine because if the pitch gets higher as the rpm's go up, that's engine noise and is a bad ground somewhere. If a constant pitch, something else. You don't have the sub or 4ch amp kooked to anything from the factory amp do you? How did you hook your deck up? Wiring harness to factory radio wores or dod you run all new wiring and bypass the factory harness?
