probably price on the aq or sundown. i just sold my mm1000.1 about a hour ago,very solid amp. the only difference i heard was crunch rates their amps at max except for gp and autotek is rated rms.The 08 autoteks are made a lot cheaper than the older ones. I would look for an old supersport or Mean machine over either. But if you are sold on getting one of those, I would say get the Crunch. I had a 4 channel Crunch that I liked a lot as well. Why neither of the forum boner amps (AQ, Sundown) around that size?
