If small foot print is what you are looking for why dont you look into a 4 channel 200-280RMS It would probably take up less space.
If 2 channel is what you are set on then model year 2000ish rockford fosgate punch 160a2 amps are small if you dont mount the pretty covers. They run 2x40rms @4ohms and that is underated. I was running two 10s off it at 2ohms and it was putting out more power than I liked (too rice sounding) I had to crank the gain down.
Check out ebay
I will look around for some more ideas
Edit: or this four channel punch 200a4
