Loaded Under-Seat Subwoofer Enclosure for Jeep Gladiator (2020–Up) 

DS18’s JT-S84LD is the ultimate bass upgrade for Jeep Gladiator owners who like it loud and clean. Loaded with four 8” ZR8.2D subwoofers, wrapped in black leather, and lit up with digital LED lighting, this setup turns your Jeep’s back seat into a bass chamber.

All the Boom, None of the Bulk
Designed to fit under the rear seat of 2020+ Jeep Gladiator models with zero seat lift required, this sealed enclosure pumps out a whopping 1800W RMS (3600W MAX) at a 1-ohm final load. 

Show-Mode Ready with Digital LED
Equipped with Digital LED Lighting, the JT-S84LD also offers a visual show. Pair it with DS18’s LC-DRM Bluetooth Lighting Module (sold separately) to control colors, effects, and patterns straight from your phone via the DS18 LC App.

Built to Bang, Built to Last
Crafted from ¾” MDF, finished in black leather and acrylic, and internally sealed for ultra-tight bass response, this enclosure is trail-tested and show-floor approved. Plus, each sub is housed in a side-ported 0.88 ft³ sealed chamber, tuned for a deep 35–100Hz response.

Digital lighting system requires DS18 LC-DRM module (sold separately). Do not connect lighting directly to the power source.
