Overview

The DEI Sound Deadening Boom Mat Headliner 4-Piece Kit is engineered to enhance the driving experience in your Jeep Wrangler by significantly reducing interior noise and improving cabin comfort. Designed specifically for Jeep models from 2007 to 2018, this peel-and-stick kit targets unwanted road, engine, and wind noise, lowering interior sound levels by 3 to 4 decibels. This reduction creates a quieter environment that allows for clearer conversations and a more enjoyable audio experience.

In addition to sound deadening, the headliner provides effective thermal insulation by cutting radiant heat from the roof, helping to maintain a more comfortable cabin temperature regardless of weather conditions. This product is ideal for Jeep owners seeking to upgrade their vehicle’s interior acoustics and comfort without complicated installation or modifications.

Construction & Design

The DEI Boom Mat Headliner is crafted from open cell polyurethane foam, a material known for its excellent sound absorption properties. This foam structure traps and dissipates sound waves, reducing noise transmission into the cabin. The polymer surface finish adds durability and protects the foam from moisture and wear, ensuring long-lasting performance.

The kit’s design is tailored to fit the contours of Jeep Wrangler headliners, allowing for a seamless installation that does not interfere with factory components or interior aesthetics. The peel-and-stick backing provides a secure bond to the roof surface, preventing sagging or detachment over time.

Performance & Sound

By reducing interior noise levels by up to 4 decibels, the DEI Boom Mat Headliner creates a noticeably quieter driving environment. This noise reduction enhances the clarity of conversations and improves the fidelity of your vehicle’s audio system, allowing music and voice to be heard with greater detail and less distortion. Additionally, the thermal insulation properties help maintain a more stable cabin temperature, reducing heat buildup from sun exposure.

Installation & Fitment

Installation is straightforward and designed for DIY enthusiasts and professional installers alike. The kit includes four precisely cut pieces that align with the Jeep Wrangler’s headliner shape. Simply peel the adhesive backing and press each piece firmly into place on the interior roof surface. No drilling, cutting, or special tools are necessary, and the process can typically be completed in under an hour.

This product fits Jeep Wrangler models from 2007 through 2018, ensuring compatibility with a wide range of trims and configurations. It also fits most Grand Cherokee headliners, offering versatility for Jeep owners looking to upgrade multiple vehicles.
