Review: Must for subwoofers. True 2mm spec. High quality. - 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.
Review: Amazing - I've put this in 4 trucks now. A 2005 GMC 2500 Duramax crew cab, a 1995 F350 Powerstroke crew cab, a 1979 F150 single cab, and most recently a 2005 F250 Powerstroke crew cab. All of which got insanely quieter. The 2005 F250 went from having to have the radio at 17 to hear it and 33 to jam out to music before the siless, to 11 to hear music 24 to jam out. I did also use the Siless 157 on the floors. Installation was a breeze. I recommend getting a 3 pound sledge hammer and use it like a rolling pin to help adhere the mat to the metal. It keeps a great seal around the whole vehicle. I don't know that I noticed much temperature holding difference but sound for sure. I used 3 boxes on the crew cabs and did the floors, doors, pillars, roof, and firewall with the 80 mil and added 157 mil on the floors and back wall and in the sub box.

## Questions & Answers

**Q: Why does Noico's 36 sq ft of 80 mil matting weight 27 lbs, but this mat with supposedly  the same specs weighs less than 17 lbs?**
A: my guess is it's due to the density and/or the specific weight of the material. like 80 ml of rubber would be different than 80 ml of lead. I purchased the Siless as the most economical choice. I would like to be able to compare products as to their damping performance specifications, (not available) but a choice  for the lighter weight material was a plus.I used 108 sq ft of Siless and saved 30 extra lbs weight that wouldn't have helped my electric vehicle's battery range. I also added a 157 ml layer of their sound matt overtop. I own a very quiet ride!

**Q: Will this help reduce engine noise in a diy generator box made of plywood?  (to inside walls away from exhaust)**
A: Thank you for your question.
You would get much better results installing butyl based material on metal. With plywood, it won't help you much.

**Q: Can this be used a a heat sheild for a Wood stove**
A: Thank you for your question.
Siless 80 mil sound deadening mat is not recommended to be used as a heat shield for wood stove.

**Q: Could you use this to keep music room noise from bothering neighbors? Specifically, could you put it on a wall?**
A: You could put it on walls. But as for suppressing noise from a neighbor, I don't think so. It's best to use acoustical tile for rooms.

### ⭐⭐⭐⭐⭐ Great Product for noise reduction in Auto Use.
*by T***O on December 29, 2025*

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!
