!CAUTION! Very powerful for it's size and 1000w output. It says capable of 1900w max and i believe it. On the first test run I blew my 12's within the first 20 mins. Of coarse I had the amp maxed out. But, the subs were a hand me down from my dad about 5-6 years old. Clarion Pro Audio 12's 600w. Neways, the punch that I got from this thing was amazing. Pure, crisp, clean, tight, bass. I have a brand new set of Cerwin Vega Vmax 12's 600w rms 1200w max. But, there at my moms on the other side of the country. So give me about a week and I'll post another update. So I can give everyone full details.
