I need a little help. I'm terrible about hooking up these RCA output cables to the 4CH - AMP. I have a USA-230 Ford Truck unit that already has the RCA cables plugged in on the backside of the radio. I don't know how the cables are connected on the back since I can't see them and don't want to take the radio out. I need to connect them to my BOSS 4 Channel Car Amplifier. How do I know where each RCA output connects to the AMP?
