Siless 80 mil (2mm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material 10 sqft (0.95 sqm)

Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.

Worked great, I installed in my jeep. definitely made a huge difference in the noise level and was really easy to work with.

I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Used this sound deadening on my 1982 gmc sierra project great quality, it reduces noise it’s very easy to install overall it works well for any car or truck.

Easy to roll out. Works great Why did you pick this product vs others?: Fair price for the amount of coverage, good quality Works well: Easy to install, rolls out great. Forms to contours well

This product was super easy to install. You will love it. Sound improvement is excellent. Cutting with utility knife or scissor allowed for precision sizing. Product stuck very well immediately and was easy to flatten using any flat firm object to fit into all sizes to properly adhere. I was also incredibly impressed by the integrity and helpfulness of the owner who kindly and quickly resolved a unique situation I encountered. The sound of my new speakers is much enhanced and there is zero vibration when I crank up the tunes. The grid measurements on the backing made it simple to cut out equal sections. And for custom spots I simply overlayed the paper side and slowly cut off pieces until I had a perfect fit! Then strip off paper, align and stick. Pull up and adjusts easily if need be. Rub flat and presto your soundproofing is in place. Double layers were no problem either right behind my woofer to ensure proper sound proofing. You will love this product. Can't wait to use it again on my next project.
