[QUOTE="gunz4me, post: 5500525, member: 596464"] You have a ground loop that is being introduced by your subwoofer amp into your component amp through the RCAs. To do it properly, you SHOULD run another set of RCAs to your subwoofer amp, but it could still introduce noise via the HU. First thing I would do is check the subwoofer amp's grounds. Many individuals DO NOT make a proper ground, which requires scraping/wire brushing/sanding the vehicle's metal to get a nice, clean, shiny surface. Next the crimp has to be nice and solid to the ground wire and the crimp has to be nice and tight against that clean/shiny metal! If that doesn't work, I would recommend grounding the shields on the RCAs to the chassis. [/QUOTE]
