I am powering a hifonics brutus 12 inch sub i bought here with this amp, I like how it has the internal cross over so it works well with subwoofers. I also use the amp to power my mains in my dj sett up, the mids and highs are also great sounding when using this amp. the amp stays really cool, i have used it for hours and it is never even warm, i have used it for outdoor gigs too, and it still stays cool. The amp is also really light weight so it made my amp rack way lighter(my old amp weighed almost 40 lbs).
