Total newbie so don’t laugh. Installing aftermarket Sony head unit, installing in a Jeep so I need the RP4-CH11 to keep SWC. I am also installing a 5 channel amp and new speakers. If I run new speaker wires from amp directly to speakers will Bluetooth phone calls and apple car play stuff still play over speakers? Or does it have to get wired into RP4-CH11 harness? I don’t understand canbus stuff.
