Autotek MM keeps going into proctect

[imhungnurnot 9]

I have an autotek mm1400.1d on a DD 9512g wired at one ohm. I set the gain using the pinned tutorial above. I bought the amp used, and my voltage hasn't dropped below 12.5 volts yet.. it usually hovers around 13-13.5 volts. Also, the amp doesn't seem to be getting too hot either. Could the problem be that the amp is damaged?

Thanks

Could be. Did you ever hook it up at 1/2 ohm like you were thinking about trying in your other thread?

Never. I was going to strap my two mm1400.1d's that I bought used. Both of them have power up/power off "pop". One operates fine other than that. The other keeps going into protect running it at 1 ohm. Maybe something is burnt up inside.. I might take the cover off to get a better look at it.
