    I just installed this amp, and 2 HDS 2.1 10’s (or the new powerband or what ever you call them now lol) in an attrend enclosure, my friend was going for Kicker and I was like, nope not happening I got a brand for you to try, and to say that I’m impressed is an understatement, for the budget amp and a prefab its slamming, almost has me wanting 6 12’s instead of 2 HDC 4 18’s, thanks soundqubed for making my decision that much harder lol, had a AQ3500 on two RE MT 18’s, and to say the least I’m going to be a loyal customer for life, already have people asking to look into getting them hooked up, and it was just installed today, and not even broke in. Thanks soundqubed for making me look good.
