You can spend serious money on the engine, paint, upholstery and audio system—but if the finished vehicle still rattles, buzzes and sounds like an empty drum, it isn’t really finished. The Dynamat Xtreme Mega Pak is the company’s largest pack of Dynamat Xtreme, the industry-leading sound-deadening material it introduced in 1989. Perfect for one complete build or multiple smaller projects, the Mega Pak includes nine oversized 24-by-48-inch sheets for a total of 72 square feet of coverage.
For more than 35 years, Dynamat has been the #1 name in automotive sound deadening, helping enthusiasts build quieter, cooler, and better-sounding vehicles. Whether you’re restoring a classic, building a Pro Touring machine, finishing a street truck, or simply improving your daily driver, Dynamat Xtreme delivers a noticeable difference the moment you close the door.
If your ride still sounds like a tin can at speed, it’s time to get serious. Dynamat Xtreme isn’t a luxury add-on — it’s a foundational upgrade for builders who want their cars to feel tight, solid, and finished. This is the same material trusted in high-end customs, competition cars, and OE applications for one simple reason: it works.
