Pioneer whining problem

[Jester1318 0]

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?

you broke it man

gotta send it in

Next time, turn everything off before you mess with it

I did that before, messed up a 550MP

There's a small resistor or fuse that blows in there. Unfortunately, you will have to have it serviced by an authorized service center like Elias stated.

yea, you probably shorted out the internal RCA grounds

I wasnt sure if that was the problem considering nothing was really hooked up, but I guess it could still happen that way, I dont know, oh well, I'll just have to get it fixed
