There's nothing more liberating than cruising down the highway blaring your favorite tunes. Crank up the volume and enjoy the beats produced by Rockford Fosgate Punch 8-Inch Subwoofer Enclosure System. Perfect addition to any factory or aftermarket system that needs an extra punch on the low-end of the frequency spectrum. Choose a structurally sound location to mount your powered loaded enclosure so the amp has an air gap for proper cooling. Follow the instructions with included hardware to complete a successful DIY installation or consult a professional. The Rockford Fosgate Punch Woofer is an all-in-1 solution for enhanced bass in any vehicle. The 8-inch high output woofer features a 300-watt internal amplifier in a compact design that fits perfectly in trucks and small cars. The unique closed-loop design ensures optimum performance between woofer, amplifier, and enclosure. For even more control of your bass, plug in the included punch level control to the amp panel and route the cable to your desired mounting position so you can do it all from the driver's seat.
