300 watts ain't much for subs...
Crown K1/K2. K1 is 1500W bridged @ 4ohms, K2 is 2500W bridged at 4ohms.
Damping factor is right up your alley at >3000, although personally, I think that spec is not TOO important.
They are small for their power because they are a "digital" amp, but they are not miniature by any standards. If you are looking for great performance in a sub amp you should investigate these.
