Summary: Purchasd this on the rec of the techs I worked with at a car audio shop. It was the amp that they all used, and MTX was in the process of phasing them out. I started off with 3 very bottom of the line 10's in a custom encloure and it was amazing, I was setting off other peoples car alarms when I was stopped next to parked cars and it dropped my rear view mirror as well.
Summary: It is one of the greatest amp i ever had. It makes any sub to go to its maximun levels. I have it working with 2 pioneer 305dvc and the bass is amazing. Just for fun with put it to 1ohm with the 2 subs and tested for Spl and it got 145.6db --- that was the fuses end.
Summary: Overall the amp performed very well. I had two 12" Cerwin Vega's and it seemed like too much power which surprised me considering the subs said they could handle 400 watts rms The power output with the bass boost cranked seemed to be around 350 watts. The amp was rated at 217 watts rms x 2 and 708 watts x 1 at 4 ohm.
