About The Product

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.
