I used the RCA Inputs, but from the original Pioneer deck that was put in, but front and rear was used, there is no interface except the GM Aftermarket Doorchime bypass, the grounds seem to be ok, used both the harness and the dash ground

I installed a AVIC D1 in a 2005 Chevy Silverado with the Bose, Sub & Speakers and now there is a humming noice when the unit is on or off and still there if the truck in NOT running... Any Suggestions???

I have my brake to a switch as it is now but do I ground both wires or do I put them to a 12volt+ wire??
