Hey I am not sure this exactly belongs here, but I figured somebody may be able to help. Anyways how do people switch between sources. Really this is going to be for my car, I want to be able to switch between regular radio and an auxillary device (portable DAT deck etc.), I figure the cheapest and easiest at this point would put some type of switch in before my external eq if that makes sense. So how would I switch between 2 RCA sources, basicly 2 pair in and 1 pair out. DC power device would be nice since it is for my car.
