[QUOTE="Jimi77, post: 8802553, member: 673702"] It does sound alot like a ground loop (noise goes away when the rcas are disconnected), but you seem to have covered that. Try moving the crossovers and keep 12v + power away from crossovers. Get a 3.5mm to rca adapter and use a phone or other source directly into the amp to isolate the problem to the amp or after the amp vs upstream of the amp. If the amp is sharing a ground or grounded close to other grounds that could be the problem. I'd also try moving the amp. Could be bad amp. Also sounds like the rcas could be picking up noise post LOC. You can try grounding the rca jacket at the amp to the amp ground. (This is probably where I'd start) Try grounding the HU to a good chassis ground or ground it to the LOC's ground point. Good luck, chasing noise issues can be a pita if you don't have some experience. [/QUOTE]
