[QUOTE="Justin89T, post: 3339090, member: 556063"] My car has the factory JBL system. I have the Metra 8113 integration harness that plugs into the RCAs of the H.U. and provides power, ground, etc. When the key is in the acc position, everything sounds GREAT. HD Radio works awesome, iPod works awesome, it sounds really good. I'm surprised how much better than the stock head unit it sounds... even though I know I shouldn't be [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] When the key is in the 'on' position with the engine NOT running there is a fairly high pitched whine coming through the speakers, regardless of what source I have selected, [I]or where i ground the h.u.[/I] when the key is in the 'on' position WITH the engine running, I still have the high pitched whine, but I ALSO have alternator whine. I have grounded the HU in two additional spots, other than the metra harness. I have disconnected the HD Radio/BT box from the harness. Just to note, I had no issues with the factory H.U. The JBL amp the car has is NOT the type that has the 1761 plug on it either so I can just bypass the amp... Not so lucky [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] I am out of ideas. Does anyone have any for me? [/QUOTE]
