The Dynamat Xtreme Sound Deadener 36 Sq. Ft. Bulk Pack (SKU: 10455) is the automotive industry's premier elastomeric vibration-damping solution designed to acoustic-proof your vehicle's cabin. This comprehensive kit contains 9 large, bulk-format sheets engineered to neutralize body panel resonance, block irritating airborne road noise, and significantly optimize the dynamic range of aftermarket car audio speaker systems.
By converting structural mechanical vibration into silent thermal energy, Dynamat Xtreme transforms thin, hollow classic car sheet metal or noisy modern door panels into a solid, premium-feeling acoustic environment.
Advanced Elastomeric Material Engineering
-
Patented Vector Chemistry: Constructed from an advanced, highly sticky butyl-elastomeric core layer that remains exceptionally stable across extreme temperature swings. Unlike cheap asphalt-based deadeners, it will not melt, outgas, smell, or lose adhesion under baking desert heat or extreme winter freezing.
-
Constrained-Layer Aluminium Shield: Covered by a durable, 4-mil thick premium aluminum constraining layer. This metallic skin structuralizes the butyl layer, forcing the underlying metal panels to flex significantly less, while acting as an effective radiant thermal barrier for your cabin floor.
-
Super-Plank Flexibility: The entire sheet is highly malleable, easily conforming and stretching over complex trunk pans, transmission tunnels, structural ribs, and inner door cavities without requiring pre-heating with a heat gun.
Complete Cabin Real Estate Coverage
The 36 square foot configuration provides the ideal footprint to execute medium-to-large coverage zones, satisfying any of the following vehicle layouts:
-
The Full-Coverage Target: Perfectly wraps 4 standard automotive door shells (both inner and outer skins) to isolate speaker back-waves and stop door skin rattle.
-
The Complete Floor Setup: Provides enough coverage to line a standard vehicle trunk floor pan, spare tire well, and rear package tray to drop exhaust drone.
-
The Cabin Base: Supplies perfect coverage to insulate a classic truck floor pan from the firewall down to the back seat riser.

Instructions
🛠️ Installation Best Practice: For absolute maximum adhesion, completely scrub the target sheet metal surface with a fast-evaporating solvent (like denatured alcohol or acetone) to strip away old factory adhesive, rust preventatives, or road wax before applying. For a professional finish, firmly press the material down from the center outward using a solid wood or rubber Dynamat Application Roller to completely eliminate trapped air pockets.
