Has anyone out there wired up their radio to be nothing but a controller? Here's what I'm thinking. Mini jack in the glovebox(?) or center console or whatever. this would go to RCA cables and the input on a 4 channel amp. Obviously the amp would then be wired to the speakers. Is there anyway to wire up the otiginal radio so it controls the power/volume? I'm sure there is....I just haven't pulled my radio to see what's behind it. Anyone done this or considered the "cons" of it?
