Dynamat 10435 Xtreme Sound Deadener Door Kit

Dynamat 10435 Xtreme Sound Deadener Door Kit Four 305mm x 914mm Self-Adhesive Sheets Covers Two Standard Doors Reduces Road Noise Improves Audio Dynamic Range

The Dynamat 10435 Xtreme Door Kit contains four 305mm x 914mm (12" x 36") pieces of self-adhesive Dynamat Xtreme, with enough material to treat two standard-size vehicle doors. Installs to inner and outer door skins without surface preparation. Reduces road noise, converts panel vibration into silent energy, and improves the dynamic range of in-car audio.

Product overview

Vehicle doors are one of the primary paths for road noise to enter the cabin. The hollow inner door cavity resonates and amplifies vibration from the road, reducing the acoustic quality of the interior and masking the dynamic range of in-car audio. Applying Dynamat Xtreme to the inner and outer door skins converts that vibration into silent energy, creating a sonic barrier that lowers road noise levels without requiring any changes to the stereo system. The improvement in dynamic range effectively increases the perceived output of the audio system by giving it a quieter acoustic environment to work in. The 10435 contains enough material for two standard doors and conforms to the curved and ribbed surfaces of door cavities without special surface preparation. Self-adhesive butyl rubber backing bonds directly to the metal panel. For best results, use a Dynaroller tool to press the sheets fully flat.

Frequently asked questions

How many doors does the 10435 kit cover?

The 10435 contains four sheets of 305mm x 914mm Dynamat Xtreme, providing enough material to treat two standard-size vehicle doors including both inner and outer door skins.

Does the 10435 require any surface preparation before installation?

No special surface preparation is required. The self-adhesive butyl rubber backing bonds directly to bare metal. Clean, dry surfaces will give the best adhesion results.

How does Dynamat improve audio performance in a vehicle?

Road noise reduces the dynamic range of in-car audio by raising the ambient noise floor inside the cabin. Applying Dynamat Xtreme to the doors reduces road noise transmission, giving the stereo system a quieter environment to work in. This improvement in dynamic range allows more detail and perceived power from the same stereo output level.

Can the 10435 be used on rear hatches as well as doors?

Yes. The 10435 is suited to any panel where noise resonation is an issue, including rear hatches and rear deck areas.

Should I use a roller tool with the 10435?

Dynamat recommends using a Dynaroller tool for best results. A roller ensures the adhesive makes complete contact with the panel surface, preventing air pockets and lifting at the sheet edges.
