Dynamat Xtreme Sound Deadening 36 sq ft Bulk Pack — 9 Sheets 18x32, Self-Adhesive Noise & Heat Control

Dynamat Xtreme is a self-adhesive automotive sound-deadening and heat-control mat sold here as a 36 sq ft bulk pack of nine 18"×32" sheets for floors, doors, trunks, hoods and panels.

If you want to reduce road noise, tame panel resonance, and improve in-car audio performance without complicated tools, this Dynamat Xtreme bulk kit gives you enough coverage for an average two-door sedan. The panels are thin and pliable, cut easily with a utility knife, and stick to clean metal and composite surfaces with a factory-formulated butyl adhesive. Made in the USA since 1989, this product is designed for DIY installs and professional restorations alike.

How does Dynamat Xtreme improve cabin noise levels?

Dynamat Xtreme turns vibrating sheetmetal into a more stable surface so panels radiate less noise and speakers perform with reduced distortion. It doesn't add significant weight, yet its dense butyl core and metallic facing dissipate and block airborne and structure-borne sounds.

• Converts resonant panels into acoustically dead surfaces
• Reduces road, engine, and wind noise transmission
• Improves speaker clarity by minimizing enclosure vibration
• Thin profile maintains fitment under interior trim

Where should I apply these 18"×32" sheets for best results?

Targeting common vibration sources yields the biggest payoff: floors, inner door skins, trunk lids and hood undersides are high-impact areas. Use the included nine sheets to cover large flat areas or cut them into smaller pieces for door skins and complex contours.

• Apply to floor pans and transmission tunnels for road-noise reduction
• Line inner door panels to reduce panel buzz and improve speaker performance
• Cover trunk floors and spare-well areas to lower cabin noise from the rear
• Stick to hood undersides to dampen engine bay resonance

Is the product easy to install for a DIYer?

Yes — installation is straightforward for anyone with basic hand tools. Clean, measure, cut, peel and press: the premade adhesive backing and flexible construction let pieces conform to curves and creases without heat guns or special adhesives.

• Peel-and-stick application with pressure-sensitive butyl adhesive
• Cut with utility knife or scissors to match contours and openings
• Roll or press firmly to eliminate air pockets and ensure adhesion
• No heavy laminates, heat-bonding, or special primers required

How much coverage and performance can I expect from this bulk pack?

This bundle supplies nine sheets sized 18"×32", totaling 36 square feet — typically enough to treat a two-door car's most critical areas. Coverage depends on vehicle size and how extensively you apply the material; strategic placement on high-vibration zones maximizes benefit.

• Nine 18"×32" sheets for flexible layout and cutting options
• 36 sq ft total coverage suitable for many compact and mid-size cars
• Thin yet dense construction balances performance with fitment
• Made in the USA with a proven butyl-based adhesive formula

Who is this for? This Dynamat Xtreme bulk pack is aimed at car enthusiasts, audio installers, restorers, and DIYers who want measurable reductions in road and panel noise while preserving interior fit and finish. If you’re upgrading a sound system, restoring a classic, or simply seeking a quieter ride without extensive fabrication, these sheets offer a practical, professional-grade solution.
