Realm LS57cx + Dynamat + Auto Sound Test Disk

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.
