You would be better off with a mono amp, as that amp is a 2 channel that will put out 250 WRMS x 2 @ 2 Ohms, it would also matter on what voice coils you have on the subs, are they dual, and what ohm are they?
i dont know anything about any of this.. My old subs got destroyed in a car accident but i managed to save everything else before they junked my car head unit, speaker box, and amp are all intact. Now I'm just trying to put everything into my new ride
