Installing Pioneer AVH-1500, got the 12v-5v converter and there no pop when I cut the stereo on but there is a constant buzz coming from the sub/amp. I've searched every combo of words I can think of and didn't find an answer. Anyone able to solve this? I was told by Crutchfield tech it's because the voltage is higher than factory going into the amp but I find it hard to believe everyone has this issue when putting a new head unit in and just deals with it

Anyone?

You may have to ground that radio... When you press the gas the humming gets louder?? Ground issue...

Dont run your rca's next to the power wire.. Check all of your ground..
Dont use cheap wiring..

Pioneer is bad for grounding issues.. Mine did the same till i attached a ground wire to the case and ground it to the body.. Even though the harness has a ground..

I was thinking it could be a grounding issue, but when the truck is running or the music is playing I can't hear the noise at all... I only hear it when I plug the harness in

Grounded to body last night, still does it. Anyone else have suggestions?

You ground the screw on the back of the radio or the ground wire itself??

Sucks.. Only pioneers have this problem..

Tried both, this is definitely a signal issue it seems like but again I can't believe I'm the only person that this has happened to lol.

Also I got the axxess steering wheel controller and gonna put that in tonight. Every wiring diagram in finding only shows the main harness, is there one out there that shows all three of the factory plugs?
