I think it is x great amp that has some nice features like thermal protection and the infrasonic filter. Unfortunately it isn't powerful enough to fully power my 15" Rockford P3's so i upgraded, but it bumps hard as he'll for my sister's 12" P3's peak power is 1000W at 1 ohm so this is a perfect amp for two 12" subs or maybe 3 10" oh and be sure to get the remote bass knob for it
