The TPA3122 from TI is very simple to connect up. Although it's a two-channel chip, connecting both together to give a bridged single output is trivial, and the circuits are shown in the data sheet. Distortion isn't wonderful, but probably adequate for your purpose.

It's even in a simple DIL chip, so soldering it to a board isn't exactly anti-gravity science!
