Upward-Firing Under-Seat Bass Upgrade

Upgrade your truck’s sound with this premium under-seat subwoofer enclosure, built from 5/8" high-quality MDF wood and finished with durable trunk-liner carpet for a clean, factory-style look. Sealed with high-quality Titebond silicone and reinforced with premium wood glue, it delivers airtight performance and long-lasting strength, while the spring-loaded terminal ensures a secure connection. Featuring an upward-firing design for enhanced bass distribution, this enclosure fits neatly under the rear seat but is not compatible with Crew-Max models.

Create Great Bass

To create great bass, you need the best in materials and engineering. Alpine's S-Series subwoofers apply technology from their higher end subs to bring you the depth and punch that'll make your tunes come alive.

And to make things even better, these subs are about an inch shallower than their predecessors, making them great candidates for locations where regular high-power subs won't fit.

High Amplitude Multi-roll

The S-W8D4 8" subwoofer can handle up to 300 watts RMS, so you can drive it hard without any worries. The tough Kevlar® treated cone stays rigid under pressure, while its rubber High Amplitude Multi-Roll (HAMR) surround enables maximum excursion for impressive performance.

Its dual 4-ohm voice coils allow for extra wiring flexibility, which helps if you plan on adding another subwoofer down the line. Also, it rocks in both sealed and ported boxes, so you can choose an enclosure that suits your tastes.
