Don't know if this is OT or not, as most of you guys seem to be into vintage boomboxes, but the following link is to a pretty sweet looking DIY boombox.

here's a quote from the maker (I pinged him re: power output on another forum):
"The amp I built is only 2x25w rms. But this is a class t 12volt amp. It's really efficient and supridingly loud and clear. It outperforms my 2x85w Samson 240v amp in every way. I'm currently looking at a chip made by Texas instruments that's a mono amp putting out 100w with pretty much the same efficiency. I'll be looking at 100w per channel. "
