Review on Enhance Your Jeep Wrangler's Audio Experience with Design Engineering 050136 Boom Mat White Sound Deadening Headliner (2007-2010) by Bobby Blanton

I received these in Revain's 'open box' and bought them at half price so I can't speak of full 'value' but they work. The Jeep is definitely quieter inside (as my noise-sensitive friend confirmed) and seems to hold heat a bit better (winter at the time of writing). The stereo quality has also improved slightly. Less of that "someone yells at you with a ton can" that wranglers are known for. Setup is very easy. Just remember to give the roof a thorough cleaning and alcohol rinse first. After you install the groove filler strips (on EACH panel), the main panels snap into place immediately. It definitely helps to have a second person to help you lay out the panels as the glue is VERY sticky and you only have to do it once.
