3) ground your rca's to radio ground/ amp ground. (rap copper wire around all 4 rca's, then ground to amp on one end, h/u on other end.)

You are getting a "ground loop" because your dealing with different ground paths between a common system..
Does the remote wire also need to be separate from the power? Thats the only one that runs with the power to the trunk.

Thank you though and everyone else, lemme try everything and ill let you guys know what does the trick
