Amazon Basics Car Sound Deadening Mat 34-Piece 9.8" x 15.7" - Heat & Noise Insulation, Vibration Dampening

These 34 adhesive mats from Amazon Basics reduce road noise, vibrations and heat transfer to create a quieter, more comfortable car interior.

If your vehicle cabin or trunk transmits rattles, engine noise, or temperature from outside, a layer of sound-deadening material can make a noticeable difference. The Amazon Basics Car Sound Deadener set includes thirty-four 9.8" x 15.7" sheets made from a butyl rubber compound with a reflective aluminum foil face and a strong self-adhesive backing. The kit is pliable for fitting to uneven surfaces, can be cut to shape, and covers roughly 36 square feet when fully deployed.

How does this mat reduce noise and vibration?

The core butyl rubber compound dampens panel resonance so metal surfaces stop ringing and vibrating. The aluminized surface helps reflect heat while adding mass to block airborne sound transmission, so both structure-borne and some airborne noises are reduced.

• Butyl rubber substrate absorbs and dissipates vibration energy.
• Aluminum foil facing increases mass and thermal reflection.
• Adhesive backing ensures tight contact for efficient damping.

Where in the car should I install these sheets?

Common placement areas include the cabin floor, trunk, doors, roof, and wheel arches — anywhere metal paneling transmits noise or heat. The pliable sheets can be trimmed to size to fit flat and mildly contoured surfaces; avoid applying to steering components or areas that require frequent removal.

• Floor pans and under seats for road and engine noise reduction.
• Door panels to minimize rattle and improve speaker performance.
• Trunk and hatch areas to control boom and vibrations.

How difficult is installation and what tools do I need?

Installation is straightforward for a DIYer: clean the surface, cut sheets to fit, peel the liner, and press firmly into place. The sheets are flexible so you can use a roller or your hands to eliminate air gaps; the kit includes installation instructions to guide sequence and surface prep.

• Basic tools: utility knife or scissors, surface cleaner, and a hand roller.
• Ensure surfaces are dry and free of grease for best adhesion.
• Trim with a sharp blade for neat edges around curves and seams.

What coverage and performance should I expect?

The set provides about 36 square feet of material using thirty-four 9.8" x 15.7" pieces, enough for targeted coverage of high-noise zones or broader coverage for smaller vehicles. Performance depends on placement, total coverage, and whether you layer material; even partial coverage often yields a measurable drop in vibration and perceived cabin noise.

• 34 pieces, each 9.8" x 15.7", totalling approximately 36 sq ft coverage.
• Best results when applied to panels that currently vibrate or transmit sound.
• Layering or combining with insulation can further improve thermal and acoustic outcomes.

Who is this for? Drivers, car audio enthusiasts, and DIYers who want to reduce rattles, improve in-cabin comfort, or enhance audio clarity will benefit from this kit. It suits anyone looking for an affordable, flexible solution to control vibration and heat transfer in doors, floors, trunks, and other metal surfaces. Professionals can also use these sheets for spot treatments during repairs or audio upgrades.
