I would like to know which wire on the D3 is the ground wire. It was installed by a local shop and now since I ripped apart my install and saw what a shabby job they did I am doing it all over. If someone could post a pic or describe the wire It would really help.

What I am doing now is reinstalling everything with better materials and I am in the process of using thicker wire for the ground and doing the RCA ground I read so much about. Thx in advance!

It's the black wire. You can find the different wire colors in the installation manual at the following link. http://www.pioneerelectronics.com/PUSA/ ... C-D3?tab=D

Thank you very much!

the ground is black. but to do the RCA grounding i got a 6mm screw for the back of the unit where a open hole was and wrapped the wire around it grounding it to the unit and then stripped and ran the wire around just one RCA ground(the outside conductor) and wrapped it with electrical tape. im not to sure if thats the right way though. how i did it
