Eric Johnson's "Victoria" (P19): Stereo head unit installation:
This is a simple 'under dash' car stereo mounting pod I've installed on the port cabintop, just inside the companway. It allows easy access from both cabin and cockpit, and is out of the way so you won't accidentally hit it. It also is reasonably protected from the weather.
I installed it using stainless screws that run through the lower (but not the upper!) fiberglass layer in the cored cabintop.
