RCA are only used IF you are running a separate AMP. If you are connecting directly to the car's speakers then Ignore the RCA's

Hi @johnian
You need to provide more information,such as what vehicle make/model/year and what headunit make/model you are trying to install, if that is what you are trying to do.
