I don't know about their amps, but their subs aren't very good at all. I have set-up my sisters system and have done everything possible to get good sound quality out of them, and I all I can get is muddy bass. Other than that I have seen 2 other setups, one with the 10's and another with 12's, and they were both poor sounding systems. I think Zane compared them with Pyramid.
