Alpine S2-DB8V-TRK Halo Series 8" Ported Dual Subwoofer Enclosure

Alpine S2-DB8V-TRK Halo Series 8" Ported Dual Subwoofer Enclosure with ProLink - Loaded with two 8" S-Series Subwoofers

Alpine S2-DB8V-TRK is built for truck owners who want deep, controlled bass in a compact setup that fits neatly under the rear seat without taking over the cabin.

Designed for Trucks That Need Space and Sound

This dual 8" ported subwoofer enclosure is made specifically with full-size trucks in mind. It slips under most rear bench seats while still delivering strong, clean low-end output. The adjustable ProLink™ system (40" to 51") helps it adapt to different cabin widths, so it doesn’t feel forced or oversized inside the vehicle.

Down-firing subwoofers combined with side-firing ports help move bass through the cabin more naturally. Instead of feeling like sound is coming from one fixed point, it spreads through the space in a way that feels fuller and more immersive.

Big Bass Without the Bulk

At the heart of Alpine S2-DB8V-TRK are two preloaded 8" Alpine S2 subwoofers working inside a precision-tuned ported enclosure. The carbon fiber/polypropylene cones paired with HAMR surround technology are designed for long, controlled movement, keeping bass tight even at higher volume levels.

With 600W RMS power handling and a frequency response of 34Hz–200Hz, the low-end stays punchy and accurate. A 36Hz tuning frequency helps bring out deeper notes without turning the sound muddy or uneven.

Flexible Fitment for Real-World Trucks

The adjustable ProLink™ structure gives Alpine S2-DB8V-TRK the flexibility to work across a wide range of trucks, including Silverado, F-150, Sierra, RAM 1500, and Gladiator JT models. It’s built to sit securely under the seat while still allowing everyday cabin use.

An integrated amplifier tray adds extra convenience by providing space for compatible Alpine amplifiers. Rubber modular feet help stabilize the enclosure on uneven flooring, keeping everything steady even on rougher roads.

Clean Design with a Premium Finish

The enclosure follows Alpine’s Halo-inspired styling, with curved edges and silver accents that give it a refined, factory-like appearance. A front link Alpine-branded bracket adds a subtle but recognizable finishing touch.

Built from CARB-compliant 5/8" MDF and wrapped in premium black carpet, the construction focuses on durability without sacrificing looks. It feels solid, structured, and ready for daily use in demanding truck environments.

Tuned for Balanced System Performance

Inside the system, dual voice coils are wired in parallel for a 2-ohm load, making it easier to pair with compatible Alpine amplifiers for optimal output. This setup helps maintain balance between power and clarity, so the bass integrates smoothly with the rest of the audio system.

Alpine S2-DB8V-TRK is designed to work best as part of a matched S-Series setup, where every component is tuned to complement the next rather than overpower it.

Built-In Engineering That Works with Your Cabin

Sound behavior matters just as much as power here. The enclosure’s vented design and side-firing ports help load bass into the cabin instead of trapping it inside the box. That means deeper impact without needing excessive volume levels to feel it.

The result is a setup that feels like it belongs in the truck, not just added to it.

Bringing It All Together

At its core, Alpine S2-DB8V-TRK blends compact design with serious low-end performance. It gives trucks a way to enjoy deep bass without sacrificing space or comfort, while still keeping everything clean, controlled, and well-integrated. It’s the kind of upgrade that changes how music feels on every drive.
