[QUOTE="Buddur, post: 2810493, member: 575352"] Hello y'all (my first post)!!! I was referred to this thread because I just purchased a Pioneer DEH-P6900UB (have yet to receive it, and of course I find out about this whine issue [I]after[/I] I bought the unit), and I **** sure don't want whining from my head unit. It appears as if the grounding of the RCAa are the culprit??? Does this mean the whining only occurs when an amp is use with the system and the RCAoutlets of the head are in use? Does this still happen when only the head unit is driving speakers w/o amp and subs? As of now, I plan to do the wrap around ground prior to install anyways because I sure don't want to have to rip it back out to do this mod. But would it be a good idea (can you even do it w/o issue) to vampire clip another ground wire to the harness ground wire and attach it to the frame somewhere (can you have more than one ground lead?). Please help me understand, Tom [/QUOTE]
