Skar Audio created this dual 8", 2,400-watt loaded subwoofer enclosure to perfectly fit 2014-2018 Chevy Silverado & GMC Sierra Crew Cab trucks. Designed for great bass performance, it fits right under the rear seat of your Crew Cab. No more hassle of matching subwoofers with enclosures; our all-in-one package makes installation easy, giving you powerful sound quickly. This enclosure includes two of our popular EVL-8 D4 subwoofers, each with a max power of 1,200 watts. The vented, single chamber, front-firing design ensures top-notch bass response, filling your truck with deep, rich sound for a better driving experience. Pre-loaded and wired internally to a 1-ohm final impedance load, it offers efficient power handling and impressive sound quality. (Make sure your amplifier is 1-ohm stable before buying, or pair it with our recommended RP-1200.1D 1200-watt amplifier.) Finished with premium black trunk-liner carpeting, this enclosure not only sounds great but also looks sleek and stylish. It blends seamlessly with your vehicle's interior, maintaining the OEM look while boosting your audio performance.
