Customer Ratings & Reviews

Great product

I ordered 2 dynamat bulk packs for my Altima. I covered the entire trunk and door panels. Really improved the sound quality by eliminating rattles and keep the sound inside the car while keeping outside noise out. Worth the money

Necessity form any install.

This was the first time I have ever used sound dampening and I will never do another install without it. Door speakers sound so much better and no buzzing or rattles. I would do the entire interior if I could. I didn't use any special tools. Just peel and stick. Make sure you use gloves because the foil is very sharp. No smell and sticks well maybe too well to any surface. Very happy with product.

Calms Nasty TRD Exhaust Noise Great Mid Bass Responce

Bought this bulk pack off Amazon for literally half the cost of it here in San Diego. I wanted to calm the annoying drone of my exhaust and improve the sound quality in my FJ Cruiser. Applied 2 layers to the rear cargo area and rear tire wells as well as covered the inner and outer skin of the front doors. It did an excelled job overall. I noticed increased mid bass output from the front 6.5 inch speakers after applying dynamat. My $400 Boston Acoustics actually sounded like the great speakers they should. Also the 2 layers in the back of the car decrease performance exhaust noise tremendously. This stuff will cut and nick your fingers badly so I’d recommend wearing thin gloves. The rubber roller is also well worth the additional expense. I picked dynamat over the competitors because I figured I’m going to have my car for a long time and only wanted to go through the hassle of install once. Didn’t want to risk applying inferior or subpar product that broke down, smelled bad, or hard to install due to lack of malleability. Very pleased overall with results. Plus it’s made in the USA.

Anyone can do it!

This product is very easy to use. Simply measure the surface cut to size and apply the sticky back to surface and smooth out. It's that easy and makes a noticeable difference in sound attenuation.

Great Investment

This product does exactly what it states. The noise in my vehicle is way down. It has a more solid feel. Night and day difference. It feels like a totally different ride. A little pricey, but worth every penny.

Dynamat Xtreme

Great durable product with relative ease of installation , looks good and delivers a great level of sound deadening. I used in in many areas of my boat where I removed old foam soundproofing .

Great stuff

Top quality, easy to form into tight spots, and lots of it! Did 4 doors and my cargo area in my 4Runner with one box and pretty much my whole BRZ with another.

Dynamat Extreme 36 Bulk Pack

Pros: easy to work with if temperature is 70 degrees. Kinda messy if it is over 95 as it will want to stick everything. Absolutely makes a difference in getting rid of road noise and really makes your stereo sound great

Con: This pack will not do the entire car I needed 2 full kits to do Hyundai XG350. I did 4 doors the trunk and the floor inside the car. You would need another kit if you did the headliner and the top of the trunk. The aluminum backing is very sharp so be careful. I had lots of cuts on my hands from this install
Cost is somewhat high

I would would recommend this product but if you could get someone else to install it that would be the way to go!!!!

easy to install

The product was easy to install. We only ordered one box to start, and it was not enough to cover the inside of our restoration Monte Carlo project, so we had to order another box. Seems like a quality, sturdy product. Haven't sound tested yet on the road.

#1 product good price

easy to install and is the best product i have used would use again

great product

super easy install. car was a 53 chevy definate difference from stock.

This stuff works!!

I put this on my doors and rear wall of my QC Dodge Diesel. It has a 4 inch straight exhaust and is mega loud. What a difference. I now can have a conversation in my cab again. Not to mention it made my system that much louder too

Dynamat 10455

Covers well- easy to work- great product and value- fast shipping

great product

I purchased 3 packs and used it in my project camaro and is great product very easy to use and after it was done it made all the difference in the world for the ride, radio system and noise.

High Quality

I was looking for a large kit to Dynamat the interior of my 93 s10 blazer. The price was awesome compared to other brands i looked into. Initially i had ordered one box of the 36SQ' bundle and shortly realized it would be no where enough. Covering every SQ inch of the interior of my truck took a total of Three boxs of 36SQ' and one door kit. The difference in sound was incredible. There was also a noticeable temperature difference in the blazing summer months. The driving noise dropped a huge amount and the volume and quality of the stereo increased. To see this product being applied you should check out my youtube channel RobHoffmann20.

fast delivery!

I received the product within 3 days of ordering it. Worked as advertised, reduced rattling dramatically, also less road noise. It's a great buy considering I paid $600 in the past to have a stereo shop install dynamat. It only took me a couple days to do and its very easy.

Great Stuff!

I used the entire pack in my trunk and it worked great. my trunk closes to a nice solid thump. and my trunk lid is nice and heavy just like it should be. I would rather pay for the name than save money on something I'm not sure about.

Huge difference

I bought this pack for use in a small truck and it made a world of difference. My windows and knobs used to rattle because of my system and now all I hear is crisp, clean bass. My catalytic converter used to rattle too and it was in my undercarriage. Now even THAT noise is going. I highly recommend Dynamat Xtreme to anyone who can afford it.

Good Product

This is a good product that goes on well and seals the interior nicely. I would highly recommend it to anyone who is restoring a vehicle.

Does What It Says

First off, let me say hats off to Sonic Delivery. I live in the middle east so I was expecting this to reach me atleast within 15 to 20 days, but it reached me within 9 days !SUPERB! Now I used the entire thing just yesterday in my Lancer GT 08 (doors & trunk)Simply put, this product does exactly what it says! No more rattles, no vibrations, Clean Sound, Deep/Hard Hitting Bass.. even @ low volumes! According to me, atleast 60% of road noise is also blocked off! It seems heavy though, in the box, but once its installed.. no worries! & for the Sonic Price, I'd recommend anyone with a car to blindly get this!! cheers!

A Must Have!

Nothing makes a great install even better then Dynamat! It makes my system sound a lot better inside the car, while also keeping all the unwanted outside road noise out of the car. Very Impressive!

Far Better Than The Original

This is my second experience using Dynamat. Used the Original in my truck which did a great job. This new generation far surpasses the original version. It is easier to work with, being thinner, weighs less yet out performs the original four fold. Having done the inside of the door as well as the door skins on my Ford Focus, it has drasticaly reduce road noise. Door virbration from the speakers hitting those low bass notes is gone, replaced with clean clear music. The added benifit is when you open and close the doors they sound as solid as any luxary car.

Removes noise from my project car

I bought this kit to help deaden the noise and vibration from my project car - an 82 DeLorean. I've thrown it all over the fiberglass floorboards, transmission hump, and in the rear of the engine bay, and rear wheel wells - and this doesn't even include the DynaLiner I have on order for heat rejection (and from what I read, additional noise rejection). I took the car for a small drive (hard to do with the seats removed during my restoration), but the Dynamat certainly did its job, and better than the regular thicker Dynamat I've used years ago. The product is thin and easy to cut with a box cutter so you can custom-form for your own application. I still have a few sheets left over but I haven't done the doors yet, but regardless, if I had to order some more, I'd do so in a heartbeat.

whole car

This is suppose to be for your whole car it did not even do the trunk over priced i would need 2 of these just to do the trunk!

dynamat extreame 36' bulk pack.

Well I ordered 2 of these packs to do the cab of my 63 GMC pick up. it was easy to use and to form, but I would suggest to buy the roller. Which is what I did after the first box. Sore fingers from trying to lay it down smooth. I also put the sheets outside in the sun to soften a bit to make them more flexible. before you start remove the seat and clean the floor get all the dust off with the vac. Give yourself as much room to move around in the cab as possible. Just little tips to make it easier on you. Love this product it made a big differance in heat and noise. Get some!

Best there is!

I have 4 boxes of this in my car currently, with 1/4" dynaliner on top of that.
Sounds crazy, but I got a great deal and wanted to try it out.
Well worth it!
Ride is now silent. Absolutely no rattle. It really makes all the panels feel solid.
I had always questioned, but now I know.
Highly recommended!

Product Review

This product performed as advertised, very easy to work with. I would recommend to anyone for soundproofing. Stays put when placed.

you can't go without it

It would not be a good idea to do an install without some king of sound deadening. Dynamat is the best and easiest to use and at the price that sonic has it for it's a great deal.

Efficient

Tried on a Ford Ka 1997, which is one of the most noisy cars on the market due to total lack of acoustic damping of the car. And it worked !
Dynamat seems extremely efficient to damp the hull or any metallic part of a car, 'cause steel parts really don't absorb any noise on their own. If applied onto all the car, you'll really get a silent ride, though not of the quietest on the market, but quieter than almost all value cars.

PROS :
— Really efficient
— Resist heat, and can be applied by any temperature
— It can be very fun to service your own car

CONS
— Expensive, though sonic's prices do soften it
— Bulk pack will not be enough for the whole car, but only 80%
— Tough piece of work to dismantle a car

great value

The product is great , easy to use and it is A great insulation

Good Product

Good stuff, installed it all that same day, and it makes a BIG difference.

To help installation, heat up the product first, it molds a lot better, also wear gloves because this product WILL cut you.

Really Works

Recommend for SPL and SQ installs. I used this product on my doors and all over my trunk and hatch. It really helps the rattles. NO MORE nasty metal clanking. Helps with road noise. I plan on getting a couple more bulk packs to do the rest of the car. I recommend to get the rubber roller to make install easy.

dynamat extreme

Dynamat extreme works great ! I actually ordered a bulk kit a trunk kit and a door kit and did all my doors the rear wall of my truck the the firewall under the hood with 1 layer and did 3 layers on my roof cuz my subs are firing up , and I also did my tag and unbolted my grill and used it where it bolts up and got rid of all the rattle I hear my music better louder crisp and clean with clarity no road noises or vibration just like a new truck I highly recommend this product to anyone serious about superior sound 5 stars all the way !!

Dynamat for 2003 F-150 Harley edition.

INSTALL TIP: I put some blue masking tape on each of the tools used on this project and tied a piece of colored ribbon onto the tweezers used to separate the paper backing from the mat. Once you put Dynamat on the floorboard, black or silver tools blend in like camouflage. This will help you find the tool you need more readily.

SAFETY: The metal you will be exposing will have very sharp, unfinished edges. You can cut yourself without even realizing it, be careful.

REVIEW: Six months ago I applied Dynamat to the whole cab of my 2003 F-150 Harley truck. With the exception of the dash, I removed the entire interior, from the headliner to the carpet. Three boxes covered everything except the rear doors. I'll get one more box to finish the job and I expect to have quite a bit left over which I will use in another vehicle. I took my time, did the job the right way and am pleased with the results. Even in temperatures over 100 degrees, there is no "smell" whatsoever. I rated "value" at 4-stars because I don't think this product needs to be as expensive as it is.

Noise Reducer

Dynamat Xtreme is easy to install, and is worth the expense. It reduces sound and heat. The 36 ft package wasn't enough to do the
entire floor pan, behind back seat and firewall, so I purchased another
package. I am considering installing it on the celing and inside the doors.

best price I could find

Dynamat works extremely well for both sound proffing and insulating. Easy to install and is a must on older cars and hot rods.

Great Deal

Good Price

Bulk needs to be bigger

I have a 03 Dodge Neon and have gone through 2 bulk packs but still need to do my headliner and floor pan. Dynamat Extreme is some great stuff. Just wish it came with more sheets.

good product

beware of imitators, dynamat is the best! i put this product in the floorboard of my jetta that's pushing a w6 and other various jl equipment. the bass sound is clear as vodka due to the dynamat. great price too.

greatest

I have too tell anyone who needs to upgrade their car, boat, truck....you could not spend more money and get the quality that comes with this product.

Cheapest Price online

Dynamat is the best sound deadener I have used, if you need some buy it from Sonic.

Great product and value

I "dynamated" my entire trunk to help reduce rattle, keep the bass inside the car and to help reduce exhaust and road noise. This did the trick. I have an '08 Charger with quite a large trunk. I was able to cover the entire trunk and trunk lid with some left to spare. You won't find a better price or customer service than you'll find with Sonic!

No more embarrassing trunk rattles

This is a great product to put in your trunk.
When I put it in I got 4 more db. Also my trunk is quieter.

WOW

Finally buying Dynamat was one of the best decisions I have made for my car. The rattle is almost completely gone, the sound quality has improved beyond belief and my subs can now hit a new level of loud. If you want great sound buy this product. You might think that you don't need the whole car kit, but if you want to decrease all outside noise and increase inside noise then Dynamat is the way to do it. The price on Sonic Electronix is great. You can never beat the prices here. If you buy the Dynamat and plan on installing it yourself go ahead and set aside three or four hours at least just for install. If you don't feel comfortable doing it yourself then go to some big time electronics shop, and they will install it for the price of a couple hours of labor. If you have never installed Dynamat before, I would not suggest trying it for the first time while doing your whole car. You won't find a better price for Dynamat, than at Sonic Electronix.

Rattle Proof

This will stop any rattle you have in your car. It will also make your system louder.

great product

this product does what it was made to do. sound insulation is great plus the package was just right in amount for the project i was working on.

Great sound damping.

My car is now a different quality. No road noise and no rattle at all.

RUN AND BUY :-)

Easy to apply and works great

This product is the best. I applied to my 1971 Super Beetle. Floor, doors, roof, and firewall. Works fantastic! Get it warm and it is super easy to put in. Definitely worth the money.

Works great

I bought the bulk pack of the extreme, I am using it in a Cobra replica that I'm building, my kit has aluminum panels for the floors and foot boxes, so you can see I needed something that would really block the noise, in my case it stops all the rattles, plus with the aluminum backed extreme, it should also block some of my engine heat.

Great Stuff

I love this stuff it's awesome. It absolutely seals in any rattle/vibration whereever u stick it to. i covered my entire car with dynamat and now my car doesnt rattle anymore u can actually hear and feel the bass rumble and mid bass in the songs from a distance when i turn the system up. no annoying rattles or bings, etc. more impact(rumble) with the bass, keeps my system nice and cool since it's insulated with the dynamat so that's gonna come in handy for the hot ass summers we have in the NYC. so, i recommend this product to anyone who's serious about their music, system, etc. buy it now and buy it from sonic cuz u wont get a better price anywhere else, thanks sonic.

Great Product

I own a FJ Cruiser and updated my sound system.
Dynamat was installed everywhere to stop vibration and reverberation.
What an amazing product. Sonic electronic has the best prices, and delivery was fast.
My FJ sounds amazing

Great performance

I definitely recommend Dynamat extreme to anyone who would like to extract the best from his car audio rig. Although is not easy to install, the resonance damping and standing waves reduction it gives you are nothing short of outstanding, really helping to obtain uncolored sound.

great stuff!

It really cuts down on noise in the cabin. before i put this in my car i could barely talk to the person right next to me because of my exhaust and engine noise, and now there is no problem. its a pain in the butt to put in, but it seems worth it to me and i cant wait to hear what it sounds like when i put my system in!

Works Great!

I bought this bulk pack of Dynamat to do a 1987 Corvette and it works great at sound deadening and keeping the heat out. Would highly recommend to anyone restoring any vehicle or putting a decent stereo system in.

this stuff is great......
i have a Saturn witch rattled like crazy being plastic and all. i installed dynamat in the trunk/trunk lid and all 4 doors sounds awesome the road noise is gone plus the trunk hatch doesn't rattle any more

Quality Dynamat in bulk

Good value for doing an entire car/truck, or for many small projects.

A must for pro sound systems.

Dynamat works great. But the bulk pack was only enough to do the Whole trunk, one of my doors, and the license plate.
I would get a couple of these to get the entire car.

Priced Right

I used the Dynamat Extreme in the floors and on the rear panel of my car to deaden the sound and vibration. The self-stick properties and ease of which it cut and conformed to the contours of my floors was great. The price was an exceptional value also. I would recommend this product to anyone that needs to insulate or deaden sound in their vehicle.

Dynamat extreme

Im loving that my car sounds so solid! I never thought it would make that big of a difference. I do think you should get this product for old schools. I have it in my 1961 impala and 1968 skylark.

Works great!

Ever since I put a single layer in my trunk i have noticed a big difference. The bass sounds much deeper and loader. I have a 97 mustang so the 36' bulk pack was just enough to fit the entire trunk. But if you have a trunk space of 13 ft3 or more your gonna want to buy two. Overal it's a great product and it's easy to install and well worth the time and money.

Excellent product, priced right

I have used several other types of sound proofing, heat reflector products. They were cheaper and I got what I paid for. After using Dynamat, I will never use a cheaper product again.

dynamat bulk pack

I would recommend this product to anybody; it’s definitely worth the price. I put 2 layers of it in my lifted s10 with 33’s and it almost took all the road noise away so I don’t need to turn up my radio to drown it out. I have 2 mtx 7500 12’s and I can hardly hear any rattles now where before it was almost embarrassing.

Works Great

I got this stuff and it had some weight to it but it is really skinny I didn’t think it would do much, but almost all of the rattles are gone(the rest are from places I can’t dynamat, like the key hole when you unlock the trunk rattles). I used this whole pack in my trunk; it just depends on where you put it. I also did it the ghetto way and used a spoon from my kitchen instead of buying a roller, You can really get in small crevices when you use a spoon. Also it is not as messy as everyone says(at least not for me).

works great!

I am very pleased with this product. I would and will recommend this to all. I was surprised at how easy it can be cut as well.

Dynamat Extreme

I first started with Sonic's 5 sheets of Dynamat Extreme to see how this stuff works. I was amazed by the improvement in the quality of sound after installation. I went back to sonic to buy more, but this time i bought 18 sheets of Dynamat to do my entire SUV. Now when I drive by my friends with the windows up and the system slamming, they dont think its me because there's no rattling and the bass doesn't travel as far.

Excellent

well, i got this bulk pack for my car and used all of it on the trunk, and it made an incredible difference in sound. It does everything they say it will do and better then i expected; and I'm a skeptical person- heck it even keeps my trunk cooler then before durring the summer, its insane i recommend everyone gets this if they want to experience true sound quality. (By the way, i have a 95 intrepid, those are family sedans and thus my trunk is absolutely huge thats why i used a whole bulk pack on it)

Nice

Neccessary for a SQ vehicle. Dynamat is usually the some of the best out there, though a little overpriced. As far as features it only does one thing. Cosmetics are unimportant because when intalled you cannot see it.

Overpriced

Save your money and buy something else other than Dynamat,I mean it works but you can get other deadeners cheaper and do just as good of a job. I have some of this in my truck from years ago so I can't complain there but I bought some NVX and Stinger roadkill from Sonic and was very impressed with both of them especially for the price difference. IMO the best deadener out there is Second Skin but it's expensive too so just buy some Stinger or NVX and you'll have money leftover from not buying this.. I think it's about time you came down on your prices DYNAMAT!

Good Stuff!

Dynamat Extreme is easy to cut and apply. Small areas can be removed to make holes for wires etc. - not as difficult or messy as I imagined. 1965 muscle car is now well insulated from outside noise and heat and doors sound solid when closed. I am very happy with it.

dynamat

I would recommend this product because seriously improves the sound quality in the vehicle

Really works!!!

I bought 2 packs at a great price from sonic electronix. I Installed it everywhere inside my doors, floors and rear deck along with entire trunk. On the highway at 70 mph i hear no road noise at all.
No Rattles from booming bass either. Buy this product!!!!!!!!!

every vehicle needs it

you'll have doubts and won't be a believer until you finally put dynamat in your vehicle. if you have a good stereo in your car/truck, putting dynamat in will make it sound like you added another subwoofer in. it helps with rattles and helps with road noise as well. every system i install, i always put dynamat in, unless the customer doesn't want to spend the money. it's WELL worth it though and the only way to prove it is to listen to your system before and after.

works wonders on all vehicles

so far I've bought 5 bulk packs and use then on all the different cars i work on. not just for bass. i use it to get the tinny sound out of roofs and quarterpanels on old car, i use it as insulation on the inside firewall to help with heat and in my trunk to keep the rattles down. plus it's just easy to use, just peel stick and roll. this is a great product and sonic is the only place that your going to find it at such a good price with out getting ripped off.

WOW

This really does help, not jsut a little but so much that u can feel the difference with out even thinkin about it and it works well with sealed cars and sonic electronix gives a better price then i got it for.

Good product but not what I expected

Easy to install but didn't quiet the noise as as i expected considering the rating

This stuff really works!

Product worked very good, Its a little pricey but its worth it if you want that luxurious feel in your car. Would and have recommended to others.

Extremely worth it.

I practically used this whole pack just in my trunk (05' Mitsubishi Eclipse) which was alittle over-kill but I definitely don't think it was enough to do both the doors and trunk, even if I used it sparingly.

It is really worth it though, I have 2 12" Kicker L7s and no vibrations at all in the trunk... and if you know anything about Eclipses, these things are like snap together miniature models which is a great cause for vibrations. The Dynamat straightened that all out.

I installed it myself with a help from a friend, the whole trunk took about 6 hours and a 12 pack, but I was taking my sweet time. I don't have much patience, so next time I think ill pay for it to be installed.

Great Product and Great Service

Very light weight (box of 36 sq.ft. wieghed 21 lbs.). Don't be fooled by the light weight...this priduct works great and does a fantastic job of deadening the metal.

Goes on with little effort. Be sure to use a roller to get into those curves and corners.

Well worth the extra money over regular Dynamat.

Versitile and simple....sums it up.

Great service and quick shipping from Sonicelectronix.

Highly recommended.

Great Product, cant go wrong

I have owned my monte carlo for about a year now and this February i installed two 15" Kicker CVR's running off a Alpine VPower 850 amp and a Power acoustik for my highs, this stuff sure adds db's to your system, no question about it. After having to superglue my rearview mirror for about the tenth time i had to finally switch to 3500lb high strength epoxy, even after scraping off the old superglue and using the acetone to clean off the glass the mirror would hold up for 5 mins at the most before falling off because of the bass, great product!!! makes a lot of people stare at you

Great product!

Very easy to place in your car. After i placed in this, my car is vibrationfree. Awesome product!
Can be used in doors, flor, roof, trunk ++

Dynamat Extreme 36\' Bulk Pack

easy to install but adds a lot of weight

Dynamat Xtreme 36' Bulk Pack (Entire Car)

This product is time consuming to install, but it is definitely worth it. Eliminates the rattles.

Great in my truck

i used this under my carpet in my k5 blazer just for noise cancellation and heat. fits right under the carpet and is a breeze to install. just make sure you install it in moderate temperatures.

there is no subistute for dynamat

i will start buy saying dyna is the best there is that ive worked with im known for installing COSMETIC dyna and ive worked with that fatmat crap that peels if you leave the slighest amount of air behind it ive also installed ballestic.there are no shortcuts when it comes to sound deadening its a great investment for your system 250 installed you will gain a lot of sound from it great but

Dynamat

I am very satisfied with this product it keeps road noise out and also took care of the many rattles in my car. Very easy to apply. Does what it says it will. Also helps with hearing new frequencies. I had stronger mids after using this on my doors

Awesome!!!

It works as stated. It's a little on the pricey side but if you are an audio fan of any sort.. buy it..

GREAT DAMPENING

This stuff works like a champion!!! the only problem is you will need more than 1 bulk pack for your car for its to be very effective

+3dB

if you want to double your sound power (+3dB) get this

Dynamat

Dynamat is easy to install. Gives your sound system better quality over all I recommend every get this. It is worth the price trust me.

Dynamat 10455

Worked great for my 40 Chevy! Used it since I was putting ac in the car and used it for insulation.

Great Product

Performs exactly the way it is advertised. I have a Ford Explorer and Ranger that I used this product in. There was enough for All 4 of the explorer's doors and the hatch plus the 2 ranger doors with one sheet left over. The Bulk Pack is the best value for Dynamat.

Little exterior noise

Own 1990 foxbody 577 hp with a rusted hatch floor with no carpet. The hatch is all metal so sound was unbearable, I couldn't here the radio, talk on the phone etc. After installing dynamat extreme it was like a car off the assembly line.

Definitely helps

The Dynamat sound ending has really helped reduce the noise level inside our 2002 Corvette Z06. Before installing this product, the engine and road noise were so loud you could barely hold a conversation. Now, although there is still some elevated noise compared to a normal 4 speed car, it is much quieter. We even just drove the car with the sound ending on a 13 hour each way road trip. Couldn't have done that before.

Dynamat FTW!

Great product, covered entire rear of my car, i have a chevy cobalt. Enchances sound quality and almost eliminates outside noise. Was slightly challenging installing as a diy project but works beautifully none the less. Thanks!

Very fast shipping, these guys were great

very good

This stuff is amazing. Stopped all the ratteling in my truck, and keeps the road noise out.... its a little pricy

Perfect

excellent product to stop those rattles. igot a 78 cadillac fleetwood brougham and the trunks on these babys are huge i need 3 extreme bulk packs just to cover it al barely but with the 2 kicker solo baric l7 15's i needed it and it worked perfect.

good

It is good and easy to install. It is very sharp when you cut it so be careful. Peel and stick and deaden my doors very well
No more rattling and less road noise

Dynamat

Great product! Big difference in sound and cancels road noise out of the car.

Great product. dont put it on in the cold

Great prodeuct i really dont have to go into detail about dynamat. It is great and stopped or eliminated most of my rattles in my trunk. i even had some left to use in my off road vehicle!

Just what i want !

Fit exactly my Mustang 68, and do a very well job (noise and heat insulation)
Easy to apply.

Dynamat installer .

The Dynamat product which I have purchased is excellent all around. I always do my home work on products that I buy and found this product excellent in quality and great value. I will definitely buy again.

RECOMENDED PRODUCT

Very good product. Applied recently on an Lotus Elise and road noise as well as engine heat are reduced significantly. Recommended.

Great product!!!

This product is exactly as it is advertised. Stops rattles and adds SPL and decreases vibrations. Gives a more compact punch when installed.

Man this site has it all and for the best prices!!! I have two kickers comp style,crunch 800 amp, memphis 500 amp, 1 farad capacitor, kenwood DDX712 in dash unit, that i have gotin all from sonicelectronics. Thxs sonicelectronics!!

My trunk used to rattle so much now that i put the dynamat in the rattle is next to none :) (I used a hole car kit just for my trunk) The dynamat is the way to go if ur trying to show off your stuff and sound good! The bass sounds a lot cleaner and hits harder!! Dynamat is worth ur money!! I didnt think that it was really going to work all that well but it surprised the s*** out of me!!!

Great Product

I've been around car audio for years and by far, Dynamat Extreme is the best as far as sound dampening. For my current set-up, 1998 Japanese Toyota Altezza, I bought (1)bulk pack (2) door kits and (2) speaker kits and that covered the trunk, back deck panel, all 4 doors and the panel under my backseat. SQ is out this world and virtually no rattle. Spend the money and improve your sound, you won't be disappointed!!!

best kit available

this stuff will help stop almost all of your rattling, help you in spl comps. I went up 5 dbs just by adding this stuff.

Works Great

Had to pull the headliner in my vehicle to replace the attachment points for a roof rack. Figured as long as I was at it, sound proof the roof. The Dynamat Extreme did a great job of deadening the whistle from the racks and Yaks.

Worlds Best Dynamat Sourcee

Got the best package deal I could of ever imagined for my 53 Chevy. It went on great and stayed nice and tight. Sealed up the hollow steel truck vibrations. If I ever need more, for another rod, this is where I'd come !!!

Dynamat

What a great product! Did the headliner, doors, under carpet and back panel of truck. The truck is completely different and the sound quality is unbelievable. HIGHLY Recommended

works good

product does what its suppose to. i have a aveo hatchback small car, but the entire bulk kit didnt cover the entire car. the roof, rear passenger doors, and spare tire well is all it covered and all of the dynamat was used. still a great product!

Nice Sound

After I installed the Dynamat', I rapidly noticed that my door speakers were louder and sounded more sharp. It's also more silent inside my vehicle. I love this product.

Quality

I bought two of the Dynamat Xtreme Bulk kits and laid them down on the floor of my Chevy Blazer, side panels, and rear door...It made it sound so much better. Used to play my volume at 45 on my pioneer stereo now i play it at 35 or 36 tops. Much nicer sound and it keeps it all inside so that you hear everything! Good stuff.

What a difference - amazing

I was always a fan of Dynamat, I think it works great and does what is supposed to. Two thumbs up highly recommended.

dynamat

The product works great. Product Shipped fast. Decent price too.

Awsome deal !!!

I just restored my 78 Chevy Malibu and this stuff was the best purchase for the project. This Dynamat Extreme is awsome! When the interior was out of the car, I used this product from the fire wall back to the trunk . I did the floor,doors,upper pillars, and trunk. It was super easy to cut and mold to place. When you put it down you are able to lift it back up again before rolling it out to straighten out a kink or something like that. Dynamat Xtreme made the road noise go away, any rattles there might have been. It is like driving in a luxurious car now. Dynamat Xtreme I can't say enough about it, Love the Stuff!!!!

Good service

Fast delivery and the cheapest i could find i will use again very happy with service

Works as advertised

Performed as promised. A little tough to install. Take your time

Great value

Great product for insulating automobile panels. I saved 25% this time by buying it here rather than from aftermarket parts provider.

A great product!

I bought this a while back to line my trunk and it did a great job of molding to my trunk and to other places in my car. when you buy this, make sure to get the dynamat roller to go with this so you can get all the dynamat in the little grooves of your car. make sure to get extreme as opposed to regular dynamat because, regular dynamat just doesnt mold well.

amazing

This stuff is amazing. I put it on the floor of my 98 tahoe with old squeeky suspension and now i cant hear any squeeks or road noise. I cant wait to cover the rest of my car in this stuff and see how quite its gunna be. worth every penny

Better then I expected

I installed this into my 95 toyota tacoma about 6 months ago, and for any one that has'nt ridden in one you can hear EVERY little road noise possible. I bought it to improve my bass wich it did an excellent job of, but it also got rid of about 70% of the road noise too. The only thing I did'nt like about the dynamat wich is true about almost any stick on sound damper is that it smells if you leave your vehicle in the sun for a long time.

Great Product

Dynamat Xtreme works well, outside noise is almost gone. Can hear the radio now in the car. Also it is easier to keep the car cooler in summer. As far as installing it does take time and a little extra work,but well worth the extra time.

Dynamat Extreme

I applied all 36 square feet of Dynamat Extreme inside the door panels and under the back seat of my 2004 Infiniti FX35. Cabin noise was greatly reduced and the impact on the quality of sound from the speakers was unmistakable. As I got the bulk package for a reduced price and did the installation myself, this was one of the best bang for the buck upgrades I have ever made.

Huge difference

I had gotten a trunk kit years ago for my car I it did very well. Less rattle more clean sound. Then when I had gotten my next car I got b-quiet. Not as good at all it was messy as heck. I had to throw away some of the clothes that I wore while installing. Dynamat Extreme is incredible though it gets in the nooks and applies easily. I'm getting five bulk backs for my new car in a few weeks.

Good Product

The product applies easily (after all of the difficult floor surface cleaning) and does a great job of reducing the interior noise and heat getting into my Corvette.

dynamat extreme bulk pack

A very good product. I bought 4 boxes to cover the floor of my SUV. It works very nicely - there may be other products that claim to be as good and are a bit cheaper, but given the permanent nature of the installation, why take any risks?

You MUST have a high quality wooden roller to apply. The home depot junk will not work at all. Spring for their roller.

Great stuff...

This is some very good deadening material but you can get the same quality stuff for alot less... unless you care about brand names look for cheaper prices.

Essential for an actual sound system 'upgrade'

The difference this makes is like night and day, get the most out of the actual components by purchasing this. There are generic brands, but why not just get the real thing. I used 2x36ft packs on my 2002 Monte Carlo SS. I wish I took measure to additionally reduce the vibration of the door panels. I had to set the Xover on my door speakers to 320 high pass because the vibration was rediculous. I think the max excursion from the speakers I chose may be causing the speaker to touch the panel itself. This product may reduce the flow of air in and out of the vehicle, my black on black car gets hot enough to roast nuts. It was winter when I did the install, a 125,000 BTU heater helped make the pieces more pliable (dont light yourself on fire). I got an experienced body man to help me do the install. Dont let an area that is hard to get stop you from thorough coverage. Doors, floorboard, trunk, and if you're really throwing money and time at it, the roof. You know how bumper stickers have a division in the backing? Make a cut like this so you can use a whole sheet, but stick only a protion on at a time. Videos on youtube may be helpful. Worth every penny, but the generic brands may be worth saving a few pennies on. I plan to get the dynamat foam pad thing for the trunk lid later.

Dynamat Extreme Bulk pack

I am Fully satisfied with this product. The price was very competitive and shipping also. I recommend it to everyone to do the best job.

worth it

Dynamat Extreme works hella good. I wrapped my trunk with 2 layers. My bass has much more energy and it's definitly louder and more accurate. I recommend the dynamat roller to help with installation...and at Sonicelectronix you get a great price.

GReat product stops anoying cheap system sounding ratle and makes your stuff seem alot louder cause theres no lose in the sound

great product

works like a champ!

Want to lower your volume, but keep the same SPL?

Dynamat helps you achieve this. This pack is more than enough for small cars, ie, Civics and Corollas. The dynamat stops vibration in the vehicle. Just by adding this to all your panels, trunk, etc. your music volume stands out above the other raucous in your car. It also eliminates noisy trunks when you have subs. It lets you hear the music not thin sheet metal. I have this in both of my cars and I wouldnt have a system in my car without it. Its a staple in any system. Also, the price here is about 50% less than its competitors. I dont know how they do it, but its dirt cheap. Wish I woulda got it from here.

GOOD STUFF

I USE TO HAVE EDEAD AND IT WORKED BUT THIS STUFF IS A LOT BETTER. STOPS THAT RATTLE GOOD AND EASY TO USE.

Great stuff

GREAT STUFF im sure you can find something like this if you don't have alot of money! but this is great BANGS HARDER

Worth Installing

I have an '89 honda civic hatchback, and I hated hearing my car make so much noise down the highway. I used the dynamat on the doors and the floor. I used all of it just to cover that, but I did double up on the floor. The difference it made was incredible, and well worth the time and money. The only downside is the weight of it all. But if weights not an issue, then definately line your car in dynamat. I suggest if you plan on laying your entire car with dynamat, buy two bulk packs.

Better than the rest

I have some of this lining my trunk and will be buying more form Sonic soon so I can do the back seat area and doors. Sonic has the best price on this stuff and while it is a little more than the other brand sound deadeners Dynamat is worth the extra couple bucks

Excellent product

Easy to apply. Easy to cut in shape. Dynamat bulk pack priced very well.

"Great Value" doesn't say enough

NINE SHEETS! 36 SQ FT!! For less than $175 AND through a website I feel I can trust to follow through. I wrapped the entire cab making this system sound great! The bass is way more solid and keeps my music where I want it, with me! Standing right next to the vehicle, there is a MASSIVE difference having the door open or closed. Awesome stuff!!

Dynamat

Ordered a ton of dynamat (all of it was there) came a couple of days early so that was nice, not the first item bought on sonic electronics, all my orders never a problem

Good results in my application

I bought the Dynamat Xtreme to use as a damping material for the bass cabinets of my loudspeakers. It was difficult and time consuming to install, having to measure, cut and place inside the cabinets. The results are very good though. The bass is much tighter and more controlled.

Awesome purchase

Definitely quiets the vibrations an noise In my car. Will always buy dynamat products

Remarkable Results

Made my 64 Falcon sound so much quieter that it's like driving a new model car. Loved the results so much I bought more to put in my daughters 350z. Made her hatchback style car sound like it had a trunk. Reduced the noise 70%
