Blackhole MAT Self-adhesive Three Layer (4.5mm thick) Damping Material (Per Sheet)

Wow. This kit which included the sound blocks in the doors, block off panels and then the black hole mat made a huge difference. Doors close with vault like quality. Sound from the stock stereo sounded 30% better , upgraded stereo is the best I have ever heard in a car. The truck rides quiet like a Cadillac. Instruction videos were awesome and I called several times for advice and support and they were always willing to help. Just an amazing company to work with if you have an audio need.

I recently purchased the Blackhole MAT Self-Adhesive Three-Layer Damping Material (4.5mm thick, 20” x 79” sheet) to install in my 2023 Ford Bronco Raptor, and I couldn’t be happier with the results.

The material was straightforward to install, and having a good Sound Deadening Installation Roller made a huge difference. The roller helped ensure the material adhered smoothly and securely, maximizing its effectiveness and saving me time during the process.

Once applied, the results were immediate and impressive. The Blackhole MAT significantly softened interior sounds, reduced road noise, and created a quieter, more refined cabin. This improvement has taken my music-listening experience to the next level, allowing me to fully enjoy the quality of my upgraded audio system.

The Blackhole MAT is a high-quality product that delivers on its promise of excellent sound insulation. If you’re considering upgrading your vehicle’s acoustic environment, I highly recommend this material—and don’t forget to invest in a good roller for the best results!

My "Nightmare" is louder than i like so i decided to sound deaden it by laying (5) sheets of Blackhole on the entire roof and back wall. It as made a substantial difference but not enough as i plan in the near future to do both doors to further improve the cabin. It was a much bigger job than expected but with great results. High quality material, no ash fault, no petroleum smell. Take your time doing it and peel off the wax paper as needed to alleviate any mistakes (once it grabs the surface it's hard to re-position it). Everyone was helpful and responsive. Great company to deal with.
