I ordered a couple of audio amplifiers, the breakout boards run on 5v (I presume the IC's do too, perfect for Arduino Projects), here's the board I got, only a couple of bucks all up, I soldered on the legs and hooked it up, sounds really impressive!
If not for the fact I've since disassembled it, i'd upload a video showing it off (both right and left channels)
infact!
just watch someone elses lol
