Boom Mat's Jeep Wrangler Sound Deadening Headliner from Design Engineering provides a simple pre-shaped peel and stick kit that dresses up the interior of Jeep hard tops while minimizing annoying outside noise and vibrations while insulating from exterior weather conditions. Riding in a Jeep is great fun except for the truck's propensity for interior noise that makes it difficult to engage in conversations or even enjoy vehicle audio systems. Now there is an easy solution. Once installed Boom Mat's Sound Deadening Headliner has been tested to reduce noise levels from 3 to 4 decibels. This is a significant change in sound level that will improve overall interior acoustics so Jeep occupants can enjoy audio system and have conversations without excessive and irritating noise distractions. Boom Mat Sound Deadening Headliner is available in black and gray for 4-door Jeep JL Wranglers, 2018 and up.
