Product Details

Stop fighting engine rumble, speaker rattle, road noise and buzzing vehicle parts! Apply Dynamat Xtreme to your vehicle's resonant surfaces and enjoy improved clarity, loudness and bass response from your car stereo. High-performance Dynamat Xtreme is lighter than Dynamat Original, four times more effective, requires no heat to apply and is recommended for vehicle tops, sides and contoured areas. Dynamat Xtreme is coated with aluminum for high temperature areas such as firewalls and floors. Depending on your needs, choose Dynamat Xtreme in either application-specific kits (pre-cut material in appropriately-sized pieces) or in sheets you can cut to fit.

Xtreme Wedge Pak
Kit contains one 18" x 32" piece of Dynamat Xtreme for general use on rear decks, doors, floors and the trunk floors. Unlike Dynamat Original, Dynamat Xtreme is also recommended for trunk lids, roofs, quarter panels and under-hood installations.

Name: Dynamat Xtreme Wedge Pak
Contents: (1) 18"x 32" (457mm x 812mm) pieces of Dynamat Xtreme
Application: Use on rear decks, doors, floors and the floor of your trunk to get more bass, more music, lower road noise and better sound.

Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper. Dynamat Xtreme conforms and fuses easily to sheet metal and other hard substrates. Material performance is optimized for temperature ranges between 14°F and 140°F (-10°C to +60°C). Material can withstand temperature extremes between -65°F and +300°F (-54°C to +149°C) and is highly resistant to aging.

Acoustic Properties

The acoustic loss factor "n" is used as a measure of a material's ability to damp structure-borne sound by stating how much vibrational energy (in steel sheets for instance) is converted to heat rather than sound. For constructions containing several layers of damping material, the combined loss factor "n comb" is used. The theoretical maximum loss factor is 1 (no vibration). An undamped 1mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynamat Xtreme applied to that panel would increase the loss factor to 0.417 @ +20°C (+68°F). Multiple layers of Dynamat Xtreme improve sound damping even more.


Dynamat Xtreme can be die cut to shape and placed onto the body surface directly on painted panels or after the sheet metal is cleaned before painting (typically at the sealer application operation). Dynamat Xtreme is used to treat metal panels, partitions, ducts, doors, bins, panels, and so forth in railroad cars, buses, automobiles, and ships. It is also used for ventilation ducts, relay cabinets, steel furniture, home appliances, sink units, computer equipment, machine tools and many other objects that suffer from vibration-produced noise.

Use scissors, knife or die to cut Dynamat Xtreme to the desired size and shape before removing the release liner. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Peel off the release liner. The simplest application technique is to bend the mat slightly and attach it along its shortest edge. Press the mat firmly into place, using a roller for larger pieces. The roller reduces the risk of leaving air pockets, which reduce Dynamat's sound damping capacity. The temperature of the mat and application surface should not be below room temperature during fitting. Heating the material is not necessary.

    Comments about Dynamat Xtreme Wedge Pak:

    I used this on my 2009 gsxr 600. My bike was hit in the parking lot so I had to fix it up. I mainly used aftermarket parts and one of them were the bar ends. The aftermarket bar ends were lighter than the oem causing a lot more vibration in the handlebars. I used the Dynamat Extreme inside the handle bars to make up for the weight and reduce the vibration. This fixed my vibration problem.
