While it is against the normal install rules- if isolating the RCA's away from everything does not resolve this problem. Try moving the remote wire so that it sits right next to the power wire on the opposite side of the car that the RCA's are on. Sometimes even the minor voltage that flows through the remote leads is enough to provide a slight influence of noise into the RCA's.
