The Ground Shaker GS-JCHV112B Sub Box is built for truck owners who want hard-hitting bass without losing 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 performance every car audio enthusiast wants. The down-firing design helps protect your subwoofer from damage while improving bass response for a deeper, tighter sound inside the cab.
Constructed from durable 5/8" high-quality MDF wood, the GS-JCHV112B is made to handle real bass without flexing or rattling. It features 0.68 ft³ of internal air volume, optimized for balanced low-frequency performance, and supports subwoofers with an 11 1/8" cutout diameter and up to 6" mounting depth. Premium Titebond wood glue and high-quality silicone sealing help create an air-tight enclosure for cleaner, more accurate bass response even at higher volume levels.
Wrapped in a rugged trunk liner carpet finish, this enclosure looks factory-installed while standing up to daily wear and tear. The compact dimensions make it perfect for truck applications, and the sturdy 22 lb construction helps reduce unwanted vibration during heavy bass hits. A durable binding post terminal ensures secure speaker wire connections for a hassle-free install. If you want powerful bass in a clean under-seat setup, the Ground Shaker GS-JCHV112B delivers the perfect balance of performance, protection, and space-saving design.
With a peak power handling of 1800 watts and RMS power handling of 600 watts, the S-W12D2 can handle high-power amplification, allowing for intense and dynamic bass reproduction without distortion. It features a dual 2-ohm voice coil configuration, providing flexibility in wiring options to match your amplifier's capabilities.
The subwoofer utilizes a cone from a specialized pulp/Kevlar composite material, offering excellent rigidity and responsiveness. This construction allows the cone to reproduce low-frequency sounds with minimal distortion accurately. Additionally, the subwoofer features a high-excursion HAMR (High Amplitude Multi-Roll) surround, allowing for extended cone movement and maximum output.
The S-W12D2 incorporates a robust motor structure with an integrated dual-stacked magnet assembly to ensure reliable and consistent performance. This design promotes efficient heat dissipation and reduces power compression, enabling the subwoofer to deliver consistent and powerful bass even during demanding listening sessions.
