MTX Audio JWTJ97C20-TN ThunderForm Loaded Dual 10" Subwoofer Enclosure – 1997-2006 Jeep Wrangler TJ (Charcoal)

FITMENT NOTE: Fits 1997-2006 Jeep Wrangler TJ models. Mounts behind the rear seat. The rear seat retains its full ability to flip and fold with the enclosure installed.

The MTX JWTJ97C20-TN ThunderForm is a custom-engineered bass solution designed to bring deep, hard-hitting low-end to the 1997–2006 Jeep Wrangler TJ without sacrificing your interior utility. This vehicle-specific enclosure is rotationally molded from high-density polyethylene, creating a highly durable, weather-resistant, and resonance-free housing that fits perfectly behind the rear seats. While older Jeeps are notoriously difficult to add high-quality audio to, this ThunderForm is pre-loaded with a pair of high-output 10-inch Terminator series subwoofers engineered for massive air movement, even with the top down. As a "Loaded" passive enclosure, it is internally wired to a highly efficient 4-Ohm final load and easily handles 400 Watts RMS, making it the perfect match for your aftermarket monoblock or 5-channel amplifier. It provides a seamless, factory-integrated look with the "Thunder" that MTX is legendary for.

I happen to be a fan of K&N air filters. Fit perfect in my vehicle. Seems like a much nicer quality filter than the cheapo filters from the parts store.

Great purchase!
Size: 1.9" x 9.9" x 11.4"
This has worked out quite well. I have had it since 2023 and have been cleaned thru about 6 maintenance schedules. It's been 2 yrs and it's in great shape. Worth every penny.
