So i installed a pioneer 9400 the other day and love it, only deal is when nothings playing the volumes anywhere about like 18-22(max is set to 40) i hear a faint high pitched static in the background, and i can honestly here it during music too since its so high pitched.
I never hot swapped my RCAs, only touched them during initial install before power was connected to unit. Like it said its very faint, dosnt get louder with rpms or anythings.
So im guessing i should just go ahead and ground them right? My cable is high end stinger and i know the RCAs good. Im wanting somthing a little more, professional/permanent then a few screws holding bare wires. My stingers are the ones with alloy caps so im also considering wraping them in electrical tape or heat shrink. Any help is appreshated
