Construction & Design

The Boom Mat Headliner Kit is constructed from high-quality open cell polyurethane foam, known for its excellent sound absorption and vibration damping characteristics. This material is engineered to be both durable and flexible, allowing it to conform perfectly to the contours of the Jeep Wrangler’s interior surfaces. The foam’s open cell structure traps and dissipates sound waves, effectively reducing noise transmission into the cabin.

The kit’s peel-and-stick adhesive backing ensures a secure bond to the vehicle’s headliner and side window areas without the need for additional fasteners or tools. The precut design guarantees a precise fit, minimizing installation time and ensuring maximum coverage for optimal performance.

Performance & Sound

By reducing interior noise by 3 to 4 decibels, the DEI Boom Mat Headliner Kit creates a quieter driving environment that enhances both comfort and safety. Lower noise levels reduce driver fatigue and improve communication between passengers. Additionally, the improved acoustic environment allows factory or aftermarket audio systems to perform at their best, delivering clearer, more detailed sound reproduction.

The kit also reduces vibration-induced rattles and resonance, contributing to a more solid and refined feel inside the vehicle.

This kit is designed for a straightforward, do-it-yourself installation. Each piece is precut to fit the 2007–2018 Jeep Wrangler’s headliner and side window liners, ensuring a perfect match without the need for trimming or modification. The peel-and-stick adhesive backing allows for quick application—simply clean the surface, peel off the backing, and press the mat firmly into place.

Detailed installation instructions are included to guide you through the process, making it accessible even for those with limited automotive experience. No special tools or professional installation are required.
