the amp he has doesnt do 2OHM bridged.

RMS Power measured at 12.5 Volts DC:
37.5 Watts x 2 into a 4 Ohm load with less than 0.05% Thd+N
75 Watts x 2 into a 2 Ohm load with less than 0.1% Thd+N
150 Watts bridged into a 4 Ohm load with less than 0.1% Thd+N

and its too small to be powering 2 of those subs. thats the reason i believe for it to be getting so hot.
