Sorry about the long title. Here's the story, if you just want to plain answer my question, just skip to the bold, thanks.
Already well I installed my system to what I thought was very good. I took a day just to run the wires and put everything back perfectly. I took my time installing everything and making sure everything worked correctly. Ill post pics in a couple days.
Anyways one day I was driving and *something* happened, its hard to explain as I don't remember exactly what happened, but there were some bad noises and some dimming lights (obviously amps clipping). Everything still works fine but now I have alt noise. I regrounded my HU the other day and it went back to normal, no alt whine. Well I went over a bump, now its back!
I pulled out my HU, and realized that if both of the rca preouts (that are not being used, just dangling) touch metal-metal of the HU chassis, the whine and horrid noise goes away. What in the heck does this mean? Do I have to ground the metal shell of the RCA preouts? Thanks for any help guys
