Product Description

Sound Assassin, our Sound Deadening & Thermal Insulation Material is a great product that is made for ALL vehicles. Our Half & Full Floor Packages were originally intended for Jeep Wranglers, but they can be (and are!) installed into any vehicle for the same, great benefits. Many customers purchase these kits for their cars, trucks and hot rod projects in addition to Jeeps. It is also great for inserting into trunk spaces and door panels for the audiophiles out there. During our 30+ years in the automotive upholstery business, we have used butyl-based sound deadening material and it has proved itself to be an excellent product and very easy to work with!

If you have questions regarding your specific vehicle, please call or email us and we'll happily assist in making the right choice for your situation.

          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.
