I just bought an Aquatic AQ AV MP 5UPT HS for my 13 RG it is a plug and play unit except for my amp. I have a Boom audio fairing amp, Boom audio bag speakers, and focal front fairing speakers. The amp doesn't have any RCA jacks to plug anything into. Surely I'm not the only one to use this setup. Is there a different harness I can buy? Or can I splice into the Boom audio harness that came with the amp (if so what color wires are what)? Please help I'm at my wits end!!
