Alright so I picked up some DD 6.5" comps and I started hooking them up today. I got one in and wanted to hear it so I hooked it all up, bridged my P400.4, and turned the key. Everything was going fine. They were sounding good but not good enough so I did a little tuning. Again, everything kept working fine and there were no issues. Because of the location of my amp, I couldn't access the rear channel adjustments so I simply turned the truck off, unhooked the amp, adjusted the rear settings to match the front ones, hooked the amp back up and walked away. A few minutes later I turn the key back on and figure I'll listen to some music for a little bit. Well when my double din finally booted up and all of a sudden I get this crazy high pitch whine. No matter what RCA's I hook up it still whines. And FWIW, I touched the two white RCA's on the amp with my finger and it did the whining still. So I've tried all kinds of stuff. Switching the RCA's, unhooking the amp and hooking it back up, etc. I need some help here guys. Any ideas what could be wrong? Something wrong with the amp? Thanks in advance...
