80 mil 10 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Nice, easy to use, did a bit for my road house but I only did the floorboard so that's prob why it wasn't a dramatic difference.

Great stuff. Use this in conjunction with the foam. My truck sounds like a luxury car. Buy more than you think you will need. It goes very fast. I have ordered several times and I still need more. It’s ok to cut. Use a razor blade to make it easier. Sticks very well. Overall I’m happy to have used this. The sound in the truck is very quiet. It’s a newer truck but they aren’t made the same as they used to be. Another benefit, the speakers are more clear too. Great purchase!

Ease of installation. Works well.

I bought these to help sound proof my network rack. They do an amazing job. So easy to install and the glue is really strong. You can cut them down to fit. I also put some in my Nas to help with vibration from the hdd. Excellent price.

Almost as good as the original DM. Perfect for tidying up those last spots without breaking the bank.

I bought these to quiet the engine noise in the cab of a side by side. I found them very easy to work with as they conform to the shapes and valleys and stick very well. What I can say is that these sheets have taken the edge off the extremely irritating noise and the tone in the cab is lower and less obtrusive. I'm glad I decided to use these.

Great cost for a quality product. The Killmat lived up to its reviews. My truck floor was not easy to cover as it has many surface features that make it difficult to press martial into the bends and shapes. This product was so easy and fun my 6 year old was able to help me.

Thick and easy install. Good quality.

Works well and good service
