            Awesome improvement

            I initially purchased the Hothead Headliner and was so impressed at the improvement that I also purchased the Sound Assassin full floor package for my 2006 TJ. There is a major improvement in The decrease of road noise and a decrease in heat as well. My a/c works great now! I can’t believe the improvement on decrease of road noise. When the road surface changes I can barely tell now!

            Excellent sound dampening.

            The sound assassin made a good difference in dampening the echo inside the vehicle as well as the road noise. After install on the hard top I still had plenty left over to install elsewhere on the vehicle. Would definitely buy again.

            Sound Assassin Works

            Installed Sound Assassin in my Jeep and it made a huge difference. My wife and I can now speak normally to each other and on a cell phone. We had to raise our voices and could hardly hear the other end of the phone prior to installing Sound Assassin. I would recommend this product to all Jeep owners.

            The headliners and sound strips are great. Cabin noise is markedly reduced. I ordered the sound strips, but they didn't come. A quick email about it resulted in them being immediately sent out with an apology. The customer service is great. I would definitely order them again and other products from Hothead.
