I'm thinking about trying out one of these little units. They are only $19.95 USD from Digi-Key.

PUI Audio, Inc. AMP2X15.

They are sold as an "evaluation board" for the TPA3110D2 chip from TI, but they look to be a pretty fine little amplifier in their own right. Data sheet link is below:

I'll have to see how it sounds. Maybe good for a subwoofer center channel.

Matt here is the date sheet for your TPA3110.
I have used the TPA6112 headphone amp it works very well. Also i have used the TPA6138A2 which has an on board negative charge pump so no capacitors in the outputs. At 5v the TPA6112 outputs 150mW and at 3.3v they both output about 40mW into a 32 ohm load.
Sorry, bit off topic but the chip number stuck a cord as i am just soldering one on a board now. I don't know what the medium power amps are like but the lower powered ones for phones are very acceptable and dead quiet if implemented properly.
