DEI Boom Mat pre-cut headliner kit for 2007–2010 Jeep Wrangler JK 4‑door is a black, four-piece peel-and-stick solution that reduces cabin noise by roughly 3–4 decibels while improving acoustics and reducing radiant heat from the roof. The pre-shaped kit installs with minimal prep, uses an open-cell polyurethane foam finish, and provides added insulation for heat, cold and audio performance.
