The Ground Shaker GS-KKPXL18B Subwoofer Enclosure is built for car audio enthusiasts who want louder, deeper bass that actually hits hard. With a larger 1.45 ft³ air volume, this enclosure is tuned to 36 Hz for that low-end punch that shakes the cabin without sounding sloppy. It’s designed to give your subwoofer more breathing room, which translates to stronger output and better overall bass performance compared to smaller boxes.
This box isn’t just bigger—it’s smarter. The precision slot port (10 1/2" H x 1 1/2" W x 20" L) is designed to move air efficiently, reducing port noise while maximizing bass output. It supports a wide range of subs with a 7 3/8" cutout and up to 10-inch mounting depth, making it perfect for high-performance drivers with larger motor structures. Just keep in mind it’s not compatible with older L7 models due to the cutout size, but for most modern subs, it’s a solid fit.
This enclosure is made from 5/8" MDF and reinforced with Titebond wood glue and silicone, so it stays tight and air-sealed even under heavy bass loads. The rugged trunk liner finish keeps it protected and looking clean, while the spring-loaded terminal makes wiring simple and secure. At 28 lbs with a larger footprint, it’s built to stay planted in your trunk and handle real pressure. If you want a box that brings deeper, louder, and more controlled bass, this one is ready to go.
