Question about Pioneer DEH-3900MP CD Player
Ouch.. :) Sounds to me like you've got a DC bleed somewhere.. kinda like when you're checking phasing ona speaker box with a 9volt battery.. I'd try checking the grounds (yer subs will still work if you have a qwerky ground coming off the back of the deck in the dash).. try hooking the amp up direct to the battery and chassis grounding it in a different spot and see what happens.. Also, I had a reciever that would chirp when ya cut it on, and it was a hairline cut in one of the outbound leads grounding on the metal in the dash.. Lemmee know if that works! :)
