my amp does 2845 rms at 2 ohms, had 2 sa-12's on it, beat the living shit out of them, the coils never even had issues, but I had some voltage drop and cause clipping so I eventually friend the tinsels on it, but I have my voltage taken care of now, and recones just need to be glued, they will take a lot of power 2 ohms will sound a lot better, but the sa could take your amp @ 1ohm no problem, with box rise you will be getting like 70%ish or less of that anyways
