Dynamat Extreme Xtreme Bulk Pack - Premium Heat & Sound Deadening Material for Cars, Trucks & RVs | Reduce Road Noise & Improve Audio Quality | Perfect for Automotive, Marine & Home Audio Installations

Used the product in a Miata MX5 NC1 (which is a convertible). I covered about 40% of the floor, trunk hood and doors of the car with the product. I also used the Dynamat Dynaliner to complete the job. I must say it does make a huge difference in deadening sounds coming from the vehicle. My ride quality has improved a great deal. I can actually listen my car radio at speed up to 100km no problem. A bit pricy, but very satisfied.
