Now that my CJ is here I'm trying to do a good minimally invasive sound system without blowing the budget. I found one plan that used an Ipod, and a small amp that looked like you could do it for $200. or so. I would like to not cut up the dash. I thought I'd go with marine speakers and just put then on the rear inner fenders. If I do cut the dash have any off you mounted a modern single DIN unit and did you need additional mounts? and ideas? pictures?
