Dynamat Xtreme Sound Deadening Door Kit – 4 Sheets / 12 Sq. Ft (Part # 10435 / Car Audio Noise Barrier)

Eliminate cabin road noise, sheet metal vibrations, and door speaker rattles with the industry-standard Dynamat Xtreme Door Kit. Specially designed to treat the inner and outer door skins of two standard-size doors, this premium sound deadening material uses a patented, lightweight elastomeric butyl core fused with an aluminum constraint layer to convert noise-causing resonance into silent thermal energy.

Applying Dynamat creates a tight acoustic barrier inside your door cavity, dramatically improving mid-bass punch, vocal clarity, and dynamic audio range without requiring heat guns for installation.

Key Features:

• Premium Acoustic Damping: Four times more damping power than standard damping sheets, preventing panel flex and distortion.

• Complete Door Kit Coverage: Contains four 12" × 36" (305mm × 914mm) sheets providing 12 sq. ft (1.11 m²) of total coverage—ideal for two doors.

• Easy Peel-and-Stick Application: High-tack Vector butyl adhesive sticks directly to interior sheet metal without needing heat guns or messy adhesives.

• Thermal & Noise Protection: Withstands extreme under-body and cabin temperature swings (-54°C to +149°C) while acting as a thermal barrier.

• 100% Brand New Condition: Genuine unused inventory in factory packaging, ready for installation.
