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.
If you are working with limited space but still want serious low-frequency impact, the Rockford Fosgate Punch P3SD4-8 shallow subwoofer is built to deliver exactly that balance. Its reduced-depth motor architecture lets it fit into tight enclosures and compact vehicle locations without losing punch or clarity. Even in a small footprint, it produces strong, controlled bass that feels tight and responsive, making it a perfect match for space-conscious car audio builds.
This subwoofer gives you flexible control over your setup thanks to its dual 4-ohm voice coil design. You can wire it for 2-ohm performance when you want more output or go to 8-ohm for different amplifier matching strategies. That kind of versatility makes it easy to integrate into a wide range of systems without compromise. With CEA-2031 certified power handling, it is designed to stay consistent under real-world listening conditions, even when pushed hard for long periods.
The P3SD4-8 uses expanded acoustic output technology with a VAST surround design that increases cone efficiency without increasing overall size. That means more bass output from an 8 inch shallow sub that is still easy to install in compact enclosures. It works well in both sealed setups for tight, accurate bass and ported designs for stronger output and deeper impact. Add in the FlexFit basket for easier alignment and the reinforced aluminum trim ring for stability and clean finishing, and you get a subwoofer that is small in size but serious in performance.
