    Installed this awesome amp last week. Tuned it useing dmm and clipping remote bass knob. Just complete satisfied with this amp. Runs extremely cool @ 1 ohm. I was concerned that there was no fuses on the outside boards but once i powered it up i was blown away. The key is the sub remote knob. PURE POWER NO CLIPPING. i will be slowly replacing my JL audio amps and switching to soundqubed. Its really a great amp. Thanks soundqubed for delivering quality… And it came a day earlier!

    Running the 1250 amp on 2x DVC2Ohm RF P3 12s at .5ohm and dear god these things sound amazing in a ground shaker box. Highly recommend amp. Nice clip light on the sub remote also!

    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.
