See the difference!

I have these installed in my 2003 Mitsubishi Eclipse and I can tell the difference. My back panels and front panels used to vibrate and rattle, but with these in, you can tell the difference.

I turn my volume up, and it doesn't get anymore distorted. Sound flows straight out of the speaker and rattling is gone.

EASY INSTALL!

For $13, you get enough Dynamat for a pair of speakers, and its worth every last penny. Dynamat should charge more because these are worth it

good value

It is very heavy duty material. Easy to use. Only thing is, for both vehicle doors to be covered; you need quite alot of it. It can be expensive.

Works Great!

Easy to use!

Works well but the price is a bit too

Dynamat extreme is the original deadener and the product works well. It's a little thin compared to competition. And the price is just way too high for what has become a commodity in mobile audio

dynamat

great product! a lil pricy for what it is but it definately makes a difference

Dynamat

This really took out the rattles that were being caused by my front door speakers. I was skeptical but it worked great. Sound improved volumes.

My Sound Is Better Than Yours.

My first Dynamat product and it was love at first sight. The installation was easy. The Kit comes with more than enough product to cover any door covering. Great buy from SonicElectronix.

would i buy again, yes

very easy to use and well worth it, seals the speakers in nicely and eliminate door vibration like you wouldn't believe

Good quality

Easy to use. Good product

awesome stuff!

easy to install and cut with a razor blade. helped the bass response on my Kicker 6 3/4" door speakers. 2005 silverado crew cab.

Get this!

Hey shoppers, I purchased this Dynamat kit and more and let me say this stuff made my system sound louder and clearer. The bass is insane! I only run 1 12"..people think I have 15's..it's great and Sonic is the most inexpensive audio spot. I only buy from Sonic! Thanks Sonic for all the great deals!

great!

works great suppresses the rattling noise. Also the price is great; this stuff is really expensive at the shops.

Good!

The dynamat extreme kit is good. Easy to apply, and seems to dampen speaker vibrations. Buying a bulk pack seems like a better option, allowing for more coverage and a greater impact on sound quality.

The Best...

Nothing really beats dynamat, and this extreme product sticks quite well and is very easy to mold into curves and angles. Great price to boot. Thanks, SE!

Best Item!

If any part of your car is rattling, get this! And for a price like this, compared to retail stores or custom shops, get it here!

Dyanmat Extreme.. The way to go

I installed these with my new Infinity 6012i's. This stuff really brings out the life of my speakers not annoying rattle, helps the speakers hit harder, and is super easy to install. Took about 5-6 hours total with all dismantaling, reassembly, and prep work. Exellent product.

Dynamat

This product is amazing! I bought the Dynamat Extreme package (the 2 10"x10") to cover up my front door panel speakers because of annoying rattling. after installing the dynamat it was amazing. Also, for this low price it is a great deal. great sound.

Transmission Noise

I used this in my 2006 Mustang GT when I installed my new Hurst shifter. They are bad about having lots on tranny mouse coming through the shift boot so I put some of the dynamat around it and works great. Sound quieter than stock

Good Product and Investment

This product helps to maintain the rattling within the door panels of the car quieter. It's an easy installation and not expensive.

Quick cheep fix

i don't have speakers in my doors and i am putting my 6X9's in there on boxes because they are 2 big so i cut my pack of this stuff into strips an layed it around the whole back of my rear hatch on my blazer on the metal not on the weather stripping took the ungodly rattle away when the bass hit great deal

great stuff

Great product. Love the easy-to-use install. Recommend for anyone with no stereo skills to use.

great deal

if you want good sound then you have to use some of this. it does work. were you buy is up to you. but at less than half price of stereo shop and you can trust this company. I'd love to do the whole car with this stuff. stop road noise hear more music. but i only did the speaker holes for now

GREAT PRODUCT

THE DYNAMAT XTREME WAS EASY TO INSTALL AND REALLY MADE THE SPEAKERS SOUND MUCH BETTER WITH NO VIBRATIONS.

It works

Made the sound bar in my Jeep sound 10 times better
