  • How to identify rca channels at the amp

    hi all, as I was running the rca’s from behind the dashboard the labels fell off. Is there a quick way to identify which rca is for which channel at the amp?

    Red is right, white is left.

      Set balance/fade to the front-left corner and change rcas at that channel of the amp until you get sound, then continue that procedure around the four corners of the car. Sub out doesn’t matter which is left or right.
