great little sub amp
Does a great job of powering a little 8" sub. Probably work for 10-12" also. Small so it fit on a little box and it has built in crossover and external sub gain.

Awesome little Amp
I used this to power my 10" R2D4 Rockford fosgate sub in my Polaris Rzr 1000 (under-dash enclosure). So far, no issues. It has not let me down after the initial 100ish miles on the trails. The bass boost knob is also nice to have.
