So, after reading countless threads on installing a stereo in my camper I ended up going in an unexpected direction. When I started out I really wanted the following things: Speakers Inside Speakers Outside MP3 Capability USB Flash Drive Support What I finally ended up doing was making a completely portable stereo: click to enlarge It plugs into your standard 12v cigarette lighter socket and comes with about 20 feet of cord. I also added 12v socket on the back of it so I could daisy chain other 12 volt items. It was a rush job because I was building it for Talladega but I'm very happy with how it turned out. The wife and I just load up a 4 gig thumb drive with music and we're ready to go. I especially like the fact that I can also take it tailgating to sporting events! You can find more pics here. Thanks for looking.
