rv stereo
I haven't done it yet, but I plan to. You will need 12v for power, antenna for radio and wires out for speakers. Note that some RVs may not have their existing speakers wired for stereo, but rather as mono. In that case I would try tying better wire to the existing wires and pulling them through. If this didn't work, and I couldn't snake wires through using a wire snake, I'd probably run them in a channel right up against the roof, perhaps hidden behind moulding.
