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.

Perfect for SXS
Delivered as expected, 10 inch kicker comp r sounds great hooked up to this Amp!
