You wouldn't think that a little sound mat would mat that much different in road noise, think again. Drove around without and then after application. Much quieter. ### ⭐⭐⭐⭐ More than just automotive uses *by M***G on Reviewed in the United States on January 7, 2014* I used this in my pellet stove to cut down on noise I was getting from a blower with bad bearing. It actually helped quite a bit. ### ⭐⭐⭐ Not what it said *by A***. on Reviewed in the United States on March 22, 2016* Advertised at 80 mil but came only 50 mil but works great --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/2838210-gtmat-80mil-ultra-5sqft-car-sound-deadening-mat-noise-insulation](https://www.desertcart.tn/products/2838210-gtmat-80mil-ultra-5sqft-car-sound-deadening-mat-noise-insulation) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-05*
