Alpine S2-DB8V-TRK
Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
Alpine S2-DB8V-TRK Dual 8” Halo S-Series Preloaded Truck Subwoofer Enclosure with ProLink™
Product overview:
The Alpine S2-DB8V-TRK is a game-changer for truck owners who refuse to compromise on bass quality or cabin space. This preloaded system features two 8-inch S-Series subwoofers in a versatile, expandable enclosure that adjusts from 40" to 51" to fit under the rear seats of almost any full-size truck. With its Halo-inspired design and side-firing ports, it delivers deep, punchy low-end performance that transforms your truck's audio system into a concert-quality experience.
Features
Seamless Connectivity & Fitment
The S2-DB8V-TRK is engineered with Alpine’s ProLink™ technology, allowing the two separate enclosures to be linked and adjusted in width. This ensures a compact, "custom-fit" look under the rear bench seat of popular trucks like the Ford F-150, RAM 1500, and Silverado/Sierra. The modular, stackable foot design further accommodates uneven truck floors for a rock-solid installation.
Safety & Convenience
Designed with the installer in mind, this enclosure includes an integrated amplifier tray (optimized for Alpine mono-power amps) that tucks the amplifier neatly between the sub boxes. This "all-in-one" approach keeps your wiring clean and saves valuable floor space, while the down-firing design protects the subwoofers from being damaged by passengers or cargo on the seat above.
Enhanced Audio & Ambiance
Experience "big bass" from a small footprint. The side-firing ports utilize the truck's cabin to maximize bass loading, creating a deeper and louder response than traditional enclosures. The system's aesthetic is inspired by the Alpine Halo Display, featuring unique curved edges and silver trim that elevate the look of your interior while the subwoofers provide a physical, chest-thumping impact.
Fine Tune Your Sound
Equipped with Alpine's redesigned S-Series S2-W8D2 subwoofers, this system is built for performance. The subwoofers feature carbon fiber/polypropylene cones and a High-Amplitude Multi-Roll (HAMR) surround for massive excursion and low distortion. Pre-wired for a 2-ohm final load, it is perfectly matched to extract maximum power from high-efficiency monoblock amplifiers.
