Have a look at www.41hz.com - these Tripath based amp kits are excellent.
The problem is that the chips that use a single 12V supply are the less powerful of the Tripath chips, and your speakers are not very sensitive.
Low power Tripath amps tend to work best with more sensitive speakers, but you may be ok at low to medium volumes.

you can power the 24V configuration with 12V, too. the 12V configuration is just lower profile (and i guess it blows up, when you try to run it with 24V)
i'm trying the amp6, because it seems much easier to build and i want to get it right. if i'm successful i can build another model
Yes, the AMP6 is a very good place to start.
I have not built the "basic", but the normal one has everything you need except connectors and a transformer.
I run mine from a 15 VAC transformer that gives about 20 VDC once it had run thru the diode bridge and been filtered. Then the regulator brought that down to about 14.4 volts. The amp really kicks with that supply!
Be sure you get a nice heatsink on the Tripath chip AND the voltage regulator. I just used the case. (You will need the insulator pad for the regulator.)

Why do you need three channels?
AMP9 could be nice, but is not ideal as it's made for low impedance speakers. Ideal is you can parallel two of the four channels to get three channels. Could work well with a mono sub....
AMP9 is through hole only (except some large diodes) so is easy to build. At 24V it is quite powerfull, much more powerfull than the AMP6...

it's not a full 5.1 setup, but i thought it's better to spend the money on three real speakers and a good amplifier instead of buying some crappy 5.1 home entertainment all-in-one system for the same price.
most of the time i'm listening to music anyway. i'm thinking about upmixing 2-channel stereo to LCR.
