Hifonics makes great amps. I just got the Hifonics Brutus 1210D, and the amp is speechless. Never over heats, no fuses to replace, blah blah blah. But i don't know about their subs. I haven't done much research on them, so sorry i really can't let you know. But if your looking for a good amp, at a great price, definitly go for the Hifonics.
