Great Sub!

This little sub was installed in the bow of my boat and wow does it make the whole system come together. This 8 inch sub is no joke!! I built a custom box behind the fiberglass that is to spec that polk calls for on this sub for a seal box. Besides JL audio, Polk audio is the only other brand of subwoofers that i trust. I have been using them for a long time and they have never disappointed me. Love my Polk audio subs!
