Sound and style for your truck. Alpine’s R2-DB8V-TRK loaded subwoofer enclosure delivers powerful bass in a versatile design specifically engineered for full-size trucks. This innovative system features two premium Alpine R2-Series subwoofers in an adjustable-width enclosure that fits under the rear seats of most crew cab trucks or in the cargo area of Jeep Wranglers and Gladiators.
The R2-DB8V-TRK combines thoughtful design, premium materials, and powerful performance to create a subwoofer solution that’s as practical as it is impressive. Its side-firing ports work with your truck’s interior acoustics to enhance low-frequency output, while the adjustable width ensures a secure, custom-like fit in your specific vehicle.
