Dual-Chamber Power, Room-Filling Bass

With dual 0.75 ft³ chambers, this enclosure delivers hard-hitting, deep, and distortion-free bass that makes every track feel alive. Its forward-firing design pushes low frequencies straight into your cabin, creating a powerful, immersive sound experience for your entire truck. Boasting a total 1.50 ft³ of internal air space, it maximizes subwoofer efficiency for stronger output and richer, room-shaking lows that transform every drive.

Built Tough, Installs Effortlessly

Crafted from 5/8" premium MDF and wrapped in durable trunk-liner carpet, this enclosure delivers long-lasting strength and a clean, factory-style appearance. Airtight sealing with high-grade Titebond silicone preserves internal pressure for punchy, accurate bass that hits every note with precision. Designed to fit securely behind your seat without removing the center console, installation is quick, simple, and stress-free—perfect for DIY truck enthusiasts who want professional-grade sound with minimal effort.

Rock-Solid Bass, Hassle-Free Setup

Dual binding-post terminals ensure secure, reliable connections that keep your subwoofers performing at their peak. Weighing 42 lbs, this enclosure delivers rugged, truck-ready durability while remaining easy to handle for straightforward installation—perfect for everyday driving or weekend sound demos. Designed for standard subwoofer baskets, it fits most setups seamlessly, though wider baskets or larger magnets may require a quick clearance check, giving you powerful, distortion-free bass every time.

Delivering a Monstrous Bass Output

Perfectly designed to fit on your vehicle's tight spots while still delivering a monstrous bass output, the Kicker 48CWRT122 comes from the company's popular rounded subwoofer series, CompRT, which is always known to be ready to give the low-frequency performance that everyone deserves.

Solokon Polypropylene Cone

The Kicker 48CWRT122 has a SoloKon polypropylene cone and a rubber surround, providing massive but accurate low-frequency performance with reduced noise at high-volume levels. These materials are also famous for their robustness to withstand the stress from the constant production of solid vibrations from the subwoofer for long hours.

High Efficiency in Absorbing Heat

Aside from its massive vents, it also has the renowned Kicker UniPlate, known for its high efficiency in absorbing heat build-up from long hours of use, especially at near-maximum volume levels. The Kicker 48CWRT122 uses its in-house Forced-Air Cooling technology to keep the subwoofer 20 percent cooler than other subwoofers.
