Message	I'll suggest running a separate ground from the battery to the amp. this will eliminate the need for an isolator. I've never had any whine noise with this practice. You can use a long Positive wire kit as it's just a piece of wire. You can try a temporary connection outside and around the car to see if it helps before installing the wire.
