When you take your portable radio to the beach are you always making sure nothing rubs against it so you keep the finish scratch free. If the kids are playing close to it you make sure they don’t have anything more dangerous than a rubber ducky since you know it will end up falling on your shiny radio. The Ammo Box Stereo by Noah Farrington is the solution to this issue, it is built like a tank because it probably spend most of its life bouncing around in one. The guts aren’t built from scratch since there is no reason to reinvent the wheel.
