:FACEPALM: thats twice this morning. just ground the damn RCAs to the chassis. take a piece of BARE wire. wrap it around the fat part of the RCA (any one of them) and then loosen up a screw on the radio chassis (the ugly aluminum and steel part of the radio) and smash the other end of the wire between the screw and chassis. it should help at least. do that and sand your ground connections under the hood. if it doesnt work youre either an idiot or the amp is a POSiv re ran the hu ground to the frame as expressed in another post along with the amp ground and iv moved the ground several times as said along with changed out the rca's and even went as far as to install a ground loop isolator. it has to be a faulty ground to case in the hu rca outputs.
What amps are you using to test this out?why the hell would you make a post on a car when you wont take the time out of your day to read the fing post jack ***, go re read the first page of the thread and you will see that iv said everything you said and that the rca grounding to the hu case is the last thing to do all chassy mounts are clean and wiring is solid. iv left the same answer as you so wtf is your point in posting??? i fell like it must be said again sorry. jack ***!!
