So up for sale is my 10 Polk Audio subwoofer. This thing sounds amazing and absolutely pounds. Very very impressed with it! However I sold my last vehicle that had a sub wiring kit in it and with my 2 children under the age of 2 years old that rides in the vehicle I do not ever get to crank my audio up anymore. Asking just $150 for the sub and box combo. Which is literally the cost of just the box by itself alone brand new. I do also have a complete subwoofer wiring kit ready and available to if interested that I could add in for just an even $175. So for that you get the sub, box, and complete wiring kit. Let me know if you would like that as well. Thanks!
