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.

Good product

Works surprisingly well in doors might be worth it more in a sub box. I could actually hear a difference immediately.

Works pretty well

Cuts down on back wave interference, as advertised. I definitely noticed a reduction in the reverberations at the mid-range frequencies; I was getting a lot of interference during palm mutes in thrash metal songs before installing these dampeners. I am pleased with the results overall, and the sound quality is better. They might not provide very much improvement in some applications, but for me they worked pretty well.

Use in a harley

Ordered this product from advise of other harley riders who wanted a better sound from their bikes speakers. Seems to work well, no complaints.

Really works!!

These little things are a 150% better than fiber-fill and they dont take up valuable space like fillers do. Ive have seen a great change in sound quality and my cones dont make weird noises any more...

Dynamat Dynaxorb Speaker Pak 11800

If you establish at doors of dynamics with the bottom boundary frequency not below 90 hertz you will very strongly gain this decision. Small enough weight, convenience and speed of installation will allow you to muffle a door of your car decently enough. If all is required to apply more low-frequency loudspeakers better certainly to apply that that more serious.

Easy to install

Seems to work well. Installed easily.

it dose make a diffrence!!!

i have a pioneer component set ran off a amp. *doing rated RMS* i seen these and gave them a try. dynaxorb did make a nice difference. these are worth the price if you want or have quality speakers and want the sound they were made to have, or better the sound. must buy! only from sonic tho of course :)

Noticeable?

I bought this product with the intent originally to tile it on the back of my sub box inside, and hopefully get a better sound response. Instead I put them in the door panels and never tried the speakers without this installed ( the speakers were brand new and never used before) I don't know if it makes much of a difference, but my miss sound very good compared to before. Then again it's a whole new speaker so I can't tell!!

Home made speaker box

I made a steel speaker box out of a small rectangle tool box to fit between the roll bars in my Toyota FJ40. I am using Pioneer 6" round speakers slammed next to each other in the box. Mounting the speakers on the hinged lid and applying the Dynamat Dynaxorb Speaker Pak 11800 in the bottom of the box. Originally the sound was tinny / and tiny. With the pads it helped bring out the high's. An open truck is not the best environment for sound quality but at least I can here my radio/player with some high's now. Bye, Ty

not much

i didn't notice much of a difference in sound after i put these in.

It works

Made the sound bar in my Jeep sound 10 times better

Great System Setup

Very detailed review of system setup, operation, etc. Takes time but well worth it.

Autosound 2000

A must have for every car audio enthusiast! Be it a basshead or SQ oriented people. It teaches you where the instrument should be, gives you an idea of what sound-staging is all about!

Buy

I am a SQ guy and bought this on a lark. Started listening and son of a gun this cd helped me out on some things and reconfirmed my ears are still pretty good. A good investment.

Great product

A must for the serious audiophile. Makes set up much easier.

Very Detailed

This disc is awesome, I wasn't far off with my own ear but this disc did help me fine tune some details in my clarity and my low end, now my system is super crisp and hits hard at the right time if you know what I mean!!!

Checking my ears

Bought this on a whim to double check my ears to see if they were as good as I think. Well, found out I'm still there. Did amps via VOM & checked my ears to see if I had speakers & sub in the ball park.
This is good for a novice and will help teach them what stuff should sound like.
