I did some checking on line, how would it work if I put in a 2 way rca switch to a rca bluetooth transmitter? I could connectd the stereo channels to the splitter, switched to A amp, B bluetooth. When I switch I can also disconnect the amps turn on so only the bluetooth gets power.
My only concern is the ground, the bluetooth is designed for marine applications and has a seperate power supply. Is there any concern as to gounding, or does the bluetooth not connect the grounds together? If so, how can I prevent the radio from damage?
