My IS2080 for your componet amp

meets your dimentions with the end caps off. Exceeds your power needs. Check the link in my sig to the FS thread. Just like new.

US Amps Xterminator?

I guess I need to read the article more carefully. Your suggestion of running the front channels stereo and the rears bridged for the sub is possible, and it's the configuration I'm thinking about.

The comments i had in mind were these (right at the end of the article):

Listening to several tracks with some bass beat, like Yello’s “Oh Yeah,” continued the clarity theme, but revealed less-than-perfect control in the bottom end. It is my opinion that this is due to the lower damping factor of this amp, like any Class D amp. Remember that damping factor is a calculation of output impedance to load impedance and higher is better, at least up to 300 or so. Putting resistance between the output devices and the speaker itself will decrease the number and results in a softer, slower, less powerful sound. (All you guys using teeny-weeny 18-gauge speaker wire for your subs, take note.) Class D outputs necessarily use inductors between the output device and the speaker terminals, which raises the impedance of the circuitry and lowers the damping factor.

and

All in all, I was very impressed by this amplifier. Although lacking a little in low-frequency performance, it had stunning sound quality in the low-mid to high frequencies, which is probably what it was designed for.

So, not sure if it will you give satisfactory performance on the low end.
