I bought an autotek mm 2500.1 quite awhile ago, and have been running it at 2 ohms, and it's been great. Onlinecarstereo.com claims it's stable at 1 ohm, putting out 2500 rms. It's a $150 amp... I'm hella skeptical, because of that, so I came here to see if anyone has an experience with the Mean Machine's running down to that load.
