When I bought it used, it had been lifted and had knobby tires on it. The road noise was horrendous. I got a little used to it, but my wife hated to go anywhere in my truck. I ordered this AggSound, 788mil, 6sqft Roll Pack Universal Sound Deadener to try to cover under the back seats and back wall area of my truck. I thought that was where a lot of the noise was coming through. It was so much more difficult to remove my carpet and material behind the seats, than it was to stick this foam in. Once I was able to get it stuck under and behind the seats on the wall, I put it all back together to go for a test drive. I could not believe the difference. Of course, I still hear road noise, but my wife and I can actually hold a decent conversation now without raising our voices. I wish I had done this much longer ago as it sounds so much quieter now.

What's the best way to install it for maximum results?** A: 1.Remove & Clean: Take off interior panels; clean and dry surfaces 2.Cut to Fit: Pre-cut insulation for doors, floor, and roof 3.Apply & Seal: Peel, stick, then seal seams with foil tape (sold separately) 4.Reinstall: Replace all interior components **Q: What's the difference between Aluminum Foil and Closed-cell Foam?What are the best sound deadening solutions for sound?** A: 394mil Aluminum Foil excels in heat blocking. 157mil Closed-cell Foam (higher density) is better for soundproofing. For best results: combine 157mil foam with Butyl Sound Deadener (sold separately) to kill vibration and block noise effectively. **Q: How do I properly install the Butyl + 157mil High-Density Closed-cell Foam combination?** A: 1. Remove, Clean & Cut. 2. Apply butyl sheets(50–60% coverage is optimal), damping vibration, reducing low-frequency noise. 3. Install foam over butyl. Effectively blocks mid-high frequency noise. 4. Check. This combo ensures optimal noise reduction. **Q: How do sound deadening materials work to reduce noise? Can it reduce road noise? Can it be used on car doors?** A: Yes, Closed-cell Foam reduces road noise through:1.Sound absorption (energy to heat conversion) 2.Acoustic impedance reflection 3.Mass law blocking of mid-high frequencies. Its structure effectively reduces road/wind noise transmission into cabin. **Q: Does it require any special tools for the installation? Is a roller necessary?** A: Basic tools: gloves, utility knife, measuring tape. A roller (sold separately) is highly recommended to ensure proper adhesion of butyl/foam. Aluminum foil tape is essential for sealing seams. Keeping surfaces clean is crucial for optimal results. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Much Better Sound in My Truck *by S***T on February 28, 2024* I have a Nissan Titan Pick Up. When I bought it used, it had been lifted and had knobby tires on it. The road noise was horrendous. I got a little used to it, but my wife hated to go anywhere in my truck.

I recently installed a subwoofer box in my son's car and was looking for ways to improve sound quality and deaden some vibration areas. I have used other varieties of isolation matting in the past that do a great job, depending on the application. I ordered this to try some different techniques. This AggSound deadener is 3/4" thick, dense and very spongy. It worked perfectly applying between overlapping plastic panels on the trunk exterior. Because of it being spongy it easily filled the recessed cavities and provided a spring effect preventing the extreme vibrations. Also works perfectly behind the license plate as well. The adhesion is very thin though holds fast when applied to a clean surface. All-in-all this sound deadening matting suited my needs in the spaces I used it. --- ## 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.vn/products/634863049-sound-deadening-mat-3-4inch-20-mm-6-54sqft-car](https://www.desertcart.vn/products/634863049-sound-deadening-mat-3-4inch-20-mm-6-54sqft-car) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
