Home made car stereos for easy portability in temporary uses

Found in a 40's chev at a car show, quickly removable when the car gets judged

Found in a semi / 18 wheeler dumptruck that the driver gets assigned occasionally, but not always, and the company that owns the trucks didn't get stereos in any of them, so this guy brings his own. For more see: http://justacarguy.blogspot.com/2009/11/more-home-made-portale-stereos-for.html
