I don't agree with the statement that the subs will be overpowered... yes, the rated power of the amp is higher than what the sub says, but in all reality, the WORSE thing for speakers is to be UNDERPOWERED... being underpowered causes distortion from lack of ability of the amp to CONTROL the sub... you are ALWAYS better to have TOO much power than to have NOT enough. You should adjust your gains properly so that you don't overdrive your subs but still have enough power to control them. This IS a proven fact. Good luck!
