Dynamat Xtreme Mega Pak

Overview

Our take on the Dynamat Xtreme Mega Pak

Ask any installer. Dynamat Xtreme sound damping material keeps road noise out, so you'll hear more music using less power, effectively increasing your amplifier's output. This damping material — a butyl composite with a layer of aluminum — conforms and fuses to automotive body surfaces such as floor pans and doors. You'll hear less unwanted noise caused by vibrations and resonance and more of your favorite music, especially in the low-frequency range.

The 10465 Mega Pak includes nine 24" x 48" sheets of Dynamat Xtreme, for a total of 72 square feet. A car door typically requires about 5 square feet of Dynamat Xtreme, but you can apply it just about anywhere. Dynamat Xtreme is designed with an energy-reflective aluminum layer ideal for high-temperature areas and high sound pressure level situations, offering four times the damping power of Original Dynamat. Warranty: 60 days.

2nd car with Dynamat

Written by: Victor from Miami, FL on July 20, 2016

Crutchfield Customer Review (What's this?)

This is the second car I use Dynamat on. First one was a 2010 Tacoma double cab. The change was tremendous. Felt like I was driving around a 50k car. I was able to do the entire floor, headliner and doors. The second was a 2014 SHO. Was not that effective, not because of the Dynamat, but because of the way Ford Glues all cables to the headliner. So to avoid ripping cables or ruining the headliner, I was only able to do the doors and floors. The change was noticeable but I wish I would have been able to do the headliner.

Pros: Makes a tin can car feel like a luxury vehicle

Cons: Adds weight to the car

Excellent Product, Very surprising results

Crutchfield Customer Review (What's this?)

I purchased this product since as a bulk package it was the best value per square foot. This covered all 4 Doors, the entire floor pan from rear seat to the firewall, the rear deck, and the entire trunk. This installation significantly reduced rattle and road noise as well as reduced the resonance of the bass coming from the trunk. I have 2- 12 inch Subs and they no longer shake the doors. While testing driving after installation, if there was no wind I would not have been able to tell I was driving. One of the downsides of my installation was the time commitment. I did the install by myself and spent about 30 hours over 3 days.

Pros: "Xtreme" -ly Effective Package went all the way

Cons: Time to install Glove highly suggested, I had many cuts on my hands and raw skin from the adhesive (from separating the mat from the backing.)

Not Just For Sound System Enhancement

Written by: TechBoyBen from Memphis, TN on April 2, 2012

When I mention that I installed DynaMat in my souped up 2001 Mustang GT, I normaly get intresting feedback because until here recently I've been rocking my stock stereo and speakers. The road noise created by the performance exhaust system, stiffer suspension, and wider tires is enough that I just never worried about music quality. So, why did I install it? Installing Dynamat in the floorpan, doors, back quarter panels, rear shelf, trunk, and trunk lid (all done with one Dynamat Extreme Mega Pack) has reduce the internal noise level in my car by what I estimate to be 40%. My wife was amazed the first time she rode in the car after the install. She was excited that she could enjoy a fun ride and be able to have a conversation without yelling over the car noise. Now if Dynamat could find a way to keep the noise out while the windows were down, I'd be in heaven! Now that the road noise is reduced so significantly, I have started playing with sound system upgrades. Suggestion: Invest in a good quality roller instead of a cheap one, a good blade to cut the pieces with, and a heat gun. I started the project without any of these and quickly realized just how valuable they were. It may add a little more to the cost, but trust me, all of it is worth EVERY PENNY!

Pros: In a normal car, it would sound silent in your car, in a throaty sports car it reduces down the noise so you can enjoy the power without comprimise!

Cons: Death by a million cuts. LOL Installation will result in minor cuts in your hands nomatter how carefull you are if you're not wearng gloves! Also, installation on a level like I did will require a full weekend. You'll want to strip the interior of your car out to do the job right, and you want to do the job right. It's not a quick fix.

Features

Dynamat 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 and requires "no heat" for an easy, moldable installation.

Self-Adhesive Sheets: Each sheet has a high-tack permanent adhesive with a peel-off plastic liner on the back of the Dynamat Xtreme.

Easy-to-Cut Materials: All materials cut easily with scissors or a razor knife.

Installation

Basic Installation Steps:
  1. Clean the mounting surface.
  2. Using a razor knife or scissors, cut the Dynamat to the desired size.
  3. Remove the blue release liner from the back of the Dynamat and apply to the mounting surface.
  4. Apply pressure, working the Dynamat into the contours of the mounting surface.
  5. Work air out with a roller tool (eliminating air pockets will ensure lasting adhesion of the Dynamat to the surface, giving you maximum damping effect).
  6. Repeat the same process for each sheet of Dynamat.

Dimensions

  • Each Sheet (9 total): W = 24", L = 48", Thickness=0.085"

Why did you buy this?

I picked the Xtreme Mega Pak for it's Xtreme value. I did not want to order 3 packages for doors/trunk/hood, so I decided to get one package for my entire car. [ Daniel  Mar 09, 2016 ]
