There is definite home theater potential as well, especially if placed adjacent to the rear and surround speakers they are driving.
You might think of offering a Home Theater package with 7 of these amps run in mono, with some sort of a price break. After all everyone is always looking for a "deal", especially for Xmas!! I bet they would be a big hit in Canada and Northern Europe in the winters when everyone stays in and watches movies.
I'll look for your booth at CES....
