Pioneer RCA grounds
Has anyone else had the whining noise from the RCAs with the 880? I was switching around some wiring today, accidently touched a speaker wire to the ground wire on the amp and all of a sudden I hear a whining when I turn the vehicle back on. When I grounded a single RCA on the front pre-out the sound nearly went away, still there just barely audible
So a couple quick questions about this....
When grounding the RCA would I have to do it to every pre-out being used? (white and red of all 3 pre-outs if all were being used?)
Is there a nicer looking way of doing this?
Should the deck just be sent to pioneer to be fixed instead?
