i love my aq1200d. has a built in clipping light which will help u make sure ur subs take the full 600 rms but dont clip to damage them. its super light weight.
and ab amps are some of the best amps you can buy as they are generally a much cleaner sounding amp but are larger and not as effecient, this is a great ab amp, my old z7000 was one of my favorite amps of all time, amazing power and sounded amazing.
