[QUOTE="crash457, post: 1625620, member: 20759"] The RCAs are shielded. They are Stinger 4000 series. I even pulled them out and ran them straight through the cab to the amp so they aren't touching anything. The noise is present even when they are unplugged. I tried unbolting the amp from the board, in case the factory amp mounted on the backside was causing noise. No change. Only thing I can think is the passive crossovers are mounted on the back of the amp board right next to the factory amp. They could be picking up noise but it seems unlikely. The fact that the additional ground wire I added from the battery to the fender seemed to improve it leads me to believe it's a ground issue. I know grounding on an aluminum truck is always going to be an issue, that's why I ran my ground all the way to the battery. I'm going to try upgrading the ground from the engine to the frame and see if that helps. [/QUOTE]
