I've added a radio I had in the garage for a few years, to my x720 with a curtis cab. I Bought the antenna at Napa, and got the speakers off the web. It comes in really well, now I can listen to some music when I'm out getting some seat time. I made the mount that you see as well. I know there's been other threads about radio's in cabs and most people use mp3 and a set of earbuds, I didn't want that. I figured I would try my luck and I'm very pleased how it came out and sounds.
