A Dynamat Speaker Kit transforms the flimsy sheet metal in your car door into a solid, non-resonant baffle. You'll enjoy improved mid-bass performance with less distortion.

High-performance Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper. It's lighter than Dynamat Original, requires no heat to apply, and is coated with aluminum for high temperature areas such as firewalls and floors. Best of it all, it's four times more effective than original Dynamat in reducing noise!

Contains two 10" x 10" pieces of Dynamat Xtreme (0.044" thick). Ideal for mounting your speaker to a contoured metal surface like a car door or rear deck.

It's Dynamat, not a lot to say about it, it just works.

Hands-on research

Product Research



Xtreme: Dynamat Xtreme provides 4 times the damping efficiency of Original Dynamat, the conforming ability of Premium Dynamat, and the radiant energy reflection of Super Dynamat. Dynamat Xtreme has an aluminum layer for high temperature areas.

Mounting: Mount the speaker as you normally would, Dynamat Xtreme will create a seal and damp the door panel to maximize the speaker's performance.

Excess: Use any excess Dynamat Xtreme to attach to the speaker basket, thus cutting down on resonance.

Adhesive: There is a high tack permanent adhesive with a peel off plastic liner on the back of the Dynamat Xtreme.

Sizing: The material cuts easily with scissors or a razor knife. Dynamat Xtreme will increase the speaker's mounting height and reduce mounting depth by approximately 0.085". It is typically used to install two speakers for maximum performance.


  • Clean mounting surface (bare metal)
  • Using a razor knife or scissors cut Dynamat Xtreme to the desired size
  • Apply Dynamat Xtreme, centering the sheet over the speaker opening
  • Apply pressure, working Dynamat Xtreme into the contours of the door panel
  • Using speaker hole as a guide, cut away center portion of sheet

Product reviews from the Crutchfield Labs

Adding Dynamat sound damping to your car quiets noise and vibration, giving you a quieter ride. This short video presents an overview of what Dynamat is and how it

Great sound and value

Written by Jude, Director, Digital Imaging, on 7/10/2014 9:24:00 AM
My son just purchased a newer car, a 2002 Pontiac Sunfire and the sound system it came with was, well, awful. We sat down together and planned a system and since he was on a budget we decided we would go with our house brand Sound Ordnance for most of it, and we are not disappointed. We installed the P65-C in the rear deck using the SA69 6X9 adapter. We then installed the P-40 in the front doors with fabricated brackets we made from the 12x12 sheet of ABS #1208900903 and then used the Dynamat #15410415 to seal it all up and add sound deadening to the doors. We chose the JVC KD-R950BT for the Bluetooth and the generous power the internal amplifier has, plus the abundant color choices made it easy to match the red backlighting in the Pontiac. We needed bass so we used the Sound Ordnance B-24 and the Rockford Fosgate #575P500X1B we had from his previous vehicle and connected it using the EFX 8 gauge wiring kit #142PA8. We spent a Sunday working on this project and have to say it exceeded my expectations on sound. It sounds clear, the bass hits as hard as you want and the total price was well within his budget. This is a great system and it was also a great day spent with my son.
