I am personally running a PowerBass ASA amp right now. No issues with it, internal build quality seems ok, power output is adequate for my application, amp does not run abnormally hot, and there are no turn-on pops. As far as the amps go I'd recommend it to anyone looking for some quality gear at good prices. The speakers I have never tried though, got nuthin to tell ya on that one! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
