These little amps not only sound good...they're a blast to build. Doesn't matter if your figuring out what chassis you want to build...building it...or wiring the amp itself. Plus, the DIYChipAmp forum is filled with a bunch of great friendly people willing to help ya out with your project. Much help from your very own Sir Ron...among many many others over there.
I've currently built one of their lm3875...battery powered. The part I'm having the most trouble with is building a enclosure for the battery power supply.

Let us know when your goin' ta build one (notice I didn't say "if") ;)

take care
