Review on Design Engineering 050179 Boom Mat Grey Complete Sound Deadening Kit Compatible With 4-Door Jeep Wrangler JL (2018-Up) by Jerardo Phi

Let's start with the installation. I removed the top and flipped it over for easier installation. Clean the top with alcohol to ensure the material adheres well. I used my apple watch to measure db without earbuds and when driving at 80mph it showed 75db, with earbuds and driving at the same speed it now reads 70db which is pretty good and took also an echo when I spoke to a passenger. Stereo sounds better too, I've only had this liner for the summer, you don't have to keep the AC on high, the cabin cools down quickly and maintains a cool temperature, toured Baja and it was a real test overall. I'm happy with the look and liner properties.
