Skar Audio engineered this custom fit, quad 8-inch ported subwoofer enclosure specifically to fit under the rear cab seat of 2017-2026 Ford Super Duty (F-250/350/450) SuperCrew Cab trucks. Unrivaled in quality, this front-firing subwoofer enclosure was designed to ensure it is a perfect OEM fit in the vehicle without taking away any additional interior space. If you are looking to achieve incredible levels of bass output in your truck, this quad 8" vented enclosure is the perfect solution for housing your subwoofers.

The ported engineering of this enclosure allows for deep and thunderous bass output across the low end frequency spectrum. Constructed out of only the finest materials, including premium-grade MDF, the quality of this box is evident from the minute you open the packaging. Our enclosures are built with careful attention to detail, and are suited to work with a wide variety of compatible subwoofers (check to make sure your subwoofers fit).

Having the proper air space is critically important for your subwoofers to perform at their best, which is why we line the internal walls of this enclosure with poly-fill, a material that artificially enlarges the volume of the box. On the rear of the enclosure is the terminal wiring cup, which internally features pre-wired 12-gauge (OFC) speaker wire leads. Finally, the enclosure is finished in an attractive, automotive-grade, black trunk-liner carpeting, allowing it to blend in with your vehicles interior.
