Upgrade your truck audio system with the Ground Shaker GS-TOYTC18B under-seat subwoofer enclosure, engineered for tight-fit installations without sacrificing bass performance. Built from durable 5/8" high-quality MDF wood, this enclosure delivers a solid, vibration-resistant structure that enhances low-frequency response for deep, clean bass inside your cabin.
Designed for serious sound performance, the GS-TOYTC18B features a fully sealed construction reinforced with premium wood glue and Titebond silicone for an airtight fit. This ensures tighter bass response, improved accuracy, and long-lasting durability. The enclosure is finished with a durable trunk-liner carpet, giving it a clean, factory-style appearance that blends seamlessly into your vehicle interior.


Perfect for space-saving installations, this upward-firing under-seat subwoofer enclosure is designed to maximize bass projection directly into the cabin. It includes a spring-loaded terminal for secure and reliable wiring connection. Please note, installation may require minor trimming under the seat depending on subwoofer height, and it is not compatible with hybrid trucks or carpeted storage compartments.

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 2 + 2 ohm 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.
