The Ground Shaker GS-JCHV18B is the perfect solution for truck owners who want serious bass without sacrificing valuable cabin space. Designed to fit neatly under the rear seat behind the driver’s side, this enclosure keeps your setup clean, hidden, and practical while still delivering the low-end punch your system deserves. Its down-firing design not only protects the subwoofer from daily wear and tear, but also helps produce deeper, tighter bass that fills the cabin with smooth low-frequency response.
This enclosure is built from durable 5/8" high-quality MDF wood, giving it the strength and rigidity needed for cleaner, more accurate bass performance. With 0.68 ft³ of optimized air space, it’s tuned to help your subwoofer perform efficiently without sounding muddy or weak. The enclosure supports subs with a 7 1/8" cutout and up to 6" mounting depth, making it compatible with a wide range of popular subwoofers. Ground Shaker also uses premium Titebond wood glue and silicone sealing to keep the box air-tight and solid, even during heavy bass sessions.
Wrapped in a durable trunk liner carpet, the GS-JCHV18B looks right at home inside your truck while resisting scratches and wear from everyday use. The compact dimensions make installation simple, and the sturdy 22 lb build helps reduce unwanted vibrations for cleaner sound. A reliable binding post terminal provides secure wiring connections, making your install easier and more dependable. If you want strong bass in a stealthy, truck-friendly setup, this enclosure gets the job done without taking over your interior.
