Skar Audio engineered this custom, vehicle specific, ported, quad 8-inch, subwoofer enclosure specifically to fit under the rear cab seat of 2019-2026 Chevrolet Silverado 1500/GMC Sierra 1500 Crew Cab trucks. Unmatched by anything else on the market today, this subwoofer enclosure was designed from the ground up by our master craftsman to ensure it is a perfect fit in the vehicle, all while preserving the limited cargo space most audiophiles are reluctant to give up.

If you are looking to achieve incredible levels of bass output in your truck, this quad 8" enclosure is the perfect solution for housing your subwoofers. Featuring a split, bi-chamber design, the enclosure is extremely strong, with each of the chambers housing two subwoofers and each utilizing their own individual ports. 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.

Additionally, we line each of the subwoofer chamber walls with poly-fill to enhance the overall depth of sound that this enclosure reproduces. From there each speaker hole features it's own independent wiring terminal cup, which is pre-wired internally to 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 your vehicles interior.
