Yea even the bass knob that came with mine is exactly the same. I think for $220 I may order one instead of a M2000D just because its $60 cheaper. I it is a good amp even when I try to torcher it it don't get too hot but I'm gonna put fans on it anyway I got 2 heavy duty 5" computer fans just need one more

Try a crossflow fan...those suckers generate some wind.
