So, this still leaves you with the issue of running a wire to the dongle with all of your RCA outs. Just ground your RCA's on the other end of the wire, against your amplifier. Smoosh a small gauge wire in-between the ground on the RCA and receptacle for your amplifier. Like I said before, just ground one of them and your entire system is grounded. Hope this helps.
this seems a bit confusing to me. My amp is in the trunk where as all the rcas are in the front at the deck can you please specify what to do? Thanks
