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.

MUSWAY is known for its small and at the same time very powerful products. The two new flat subwoofers also join this tradition. Due to their design, they also suitable for installation locations that have little space in depth when shallow installation dimensions are a must. With an installation depth of 78 mm for the 8" (20 cm) and a sensationally low 87 mm for the 10" (25 cm) subwoofer, they are the ideal problem solvers for special installations.
A particularly flat subwoofer should of course sound good and must be robust. That is why MUSWAY uses special and very hard cones made of the composite materials glass fiber and carbon . No savings were made on the drives either: the woofers have 40 or 45 ounce magnets and are driven by 50 mm dual voice coils, which are also very long wound. With Xmax values ??of +/- 15 mm, both woofers ensure a decent stroke. With 250 or 300 watts RMS, they are also very resilient, so that no compromises have to be made.
