There amps are some of the best for the price. At least there stuff about 3 years ago is!:-) I have 3 of there amps, I've had them for 3/4 years and have no problem with them. There subs are also ok for the price, not that great in build quality or sq, but they get pretty loud.
i have 2 a2200hcx amps from 2001 and they pund hard and sound good but the high current amps MEAN high current and my stock setup is not good enough OTHERWISE very good
It depends on wich series of amps you are talking about. the A800HCT, and the A2300HCT are really good. Like with there subs, I'm sure some of there other moddles aren't that great.
like all brands they have the low end and high end lines. the hcx, hct, hcq lines are all VERY good others i dont have experience with. i hear not so good
