Designed for Trucks: Your truck works hard, and your bass should too. The S2-DB8V-TRK pairs Alpine’s redesigned S2-W8D2 8″ S-Series subwoofers with a space-saving ProLink™ enclosure that fits neatly under the rear bench seat of most full-size trucks. It delivers deep, accurate bass while preserving the comfort and utility of your cabin.



Big Bass Performance: The S2-DB8V-TRK delivers powerful, accurate bass thanks to its two preloaded S2-W8D2 8″ S-Series subwoofers and precision-tuned, ported enclosure. The carbon fiber/polypropylene cones and Alpine’s exclusive HAMR surround allow for long, controlled excursion, producing deep, impactful lows without distortion. Down-firing design and side-firing ports maximize cabin loading, so you hear and feel every note.



Flexible Fitment: A ProLink™ bracket connects the dual subwoofer enclosures and adjusts from 51″ to 40″, giving the S2-DB8V-TRK the flexibility to fit a wide range of full-size trucks and custom applications. Between the enclosures is an integrated amplifier mount tray that accommodates a variety of Alpine amplifiers, including the S2-A60M Mono Power Amplifier and the S2-A55V 5-Channel Amplifier (both sold separately). Adjustable rubber feet provide stability and help the enclosure sit level on uneven truck floors.



Alpine Halo Design: The S2-DB8V-TRK features a premium design inspired by the Alpine Halo Display. The enclosure’s curved edges are accented with silver trim, while the front link bracket sports an Alpine logo badge for a clean, finished look. Built from rugged 5/8″ MDF and wrapped in premium black carpet, it not only delivers big bass but also enhances the style of your truck’s interior.



Tuned for S-Series: The S2-DB8V-TRK is engineered to perform with Alpine’s S-Series sound system line. Its dual S2-W8D2 subwoofers feature dual voice coils wired in parallel for a 2Ω load, making it an ideal match for Alpine amplifiers like the S2-A60M Mono Power Amplifier or the S2-A55V 5-Channel Amplifier (both sold separately) for optimal power and performance.
