This product ships in 1 business day
Calculated at checkout

Product Description

This Damplifier box comes with 10 sqft (5 sheets) at 12" x 24" each. Enough product to cover a small sized vehicle hood or a small ceiling.

Damplifier our original CLD sheets of 1mm American made butyl rubber on a 6.5 annealed foil, black with a ghosted black SS logo. We designed Damplifier to compete against the best and most popular constraint layer dampers (CLD) the industry has to offer while weighing and costing much less! These sheets will form a strong bond to the metal and kill vibration noises cause by structure borne noise.

Compare the weight & foil thickness to everything else, and you will see, Damplifier is the best automotive sound deadening value in its class! 

With a weight of .35 lbs. per square foot and a 6.5 mil thick foil constraining layer, this self adhesive CLD vibration damper helps insure a cool and quiet ride by killing structure borne vibrations, noise and heat, while saving weight and money.

Thanks to the high temperature & high rubber content butyl adhesive, you will not have to worry about this automotive insulation falling off, peeling, or melting. Damplifier is the perfect automotive sound deadener for every area of the vehicle. Simply cut, peel and stick this foil backed vibration damper under your carpet and upholstery to get better sound deadening results than any other product in its price class!

Damplifier products contain no asphalt, no tar, and no cheap fillers. Because of this they have a very high heat rating of 450 degrees Fahrenheit and can be used inside engine bays, upside down, and wherever you want to kill vibration noise. 

When it comes to automotive vibration damping and sound deadening, Second Skin Damplifier is the best automotive CLD (constraint layer damper) in its class. No other CLD vehicle sound deadener is as affordable as Second Skin Damplifier. No other automotive sound deadener competes at this price point, and no other noise damping CLD mat to date, has a more proven track record  for sound & noise reduction in automobiles!

Typical Places of Use:

  • Door Skins - Outer Skin & Inner Door Frame.
  • Floor - From the front firewall all the way back to rear deck seat wall.
  • Firewall - Cabin side firewall or engine side firewall (450 degree heat rating). 
  • Van/Semi/SUV Panels - All over those large, flimsy, resonating sheets of metal.
  • Pillars - A, B, and C pillar areas. 
  • Trunk - Floor of trunk, walls of trunk, and trunk lid. Don't forget to get that spare tire area covered too.
  • Generator Boxes - RV, Van, or any place a generator is used, place the product around the generator enclosure to kill the vibration noise (Must be 2" away from generator heat sources)
  • Computer tower walls - Kills the vibration noise resonating through the metal wall.
  • Headphone Mods - Open up your over the ear headphones and place some on the shell to increase music sound.
  • Screen Doors - Apply the product in strategic places throughout the door to stop the load banging when closed.
  • Money Counting Machines - Used inside of shell to quiet down the noisy coin dropping.
  • Warehouse Carts - Apply to the bottom of the cart to reduce tinny, clunky noises. 
  • HVAC Ducts/Units - Applied tot he metal ducts or unit housings to cut down on the vibration noise.


  • 6.5 mil  foil - BLACK

  • Higher rubber content & Less filler content = better sound deadening performance

**Alway use caution when handling Damplifier products the foil edges are very sharp**

***We recommend cleaning all surfaces with denatured alcohol before applying product. ***

Noise Reduction Uses...

The first acoustical problem in any sound deadening project is structure borne noise This is the harmonic resonance that is emitted from the cars sheet metal panels, similar to a wind chime. Unlike wind chimes however, our cars are not tuned to any specific musical frequency, so what we end up hearing is the road noise, engine rumble and exhaust drone.

Damplifier is the perfect sound deadener for this job.
Stopping the vibrations on your cars metal panels is much like stopping a noisy wind chime with your hand. Once the vibrations stop, the structure borne noise stops. Sound deadening defined!

Traditional noise damping mats are mostly inefficient mass loaders; heavy & foul smelling tar boards that work by adding weight to the cars metal to quiet it down. This technology is over 50 years old, and for some reasons, is still being promoted by many of our sound deadening competitors on the internet.

Damplifier is not a mass loader or a heavy tar board sound deadener.
It is a constraint layer viscoelastic damper (CLD) that converts the vibration energy in to low level heat. This conversion of energy makes it 300% more efficient than traditional mass loaded tar boards and asphalt sound deadeners while weighing half as much!

Simply cut, peel and stick this automotive CLD vibration damper to the interior sheet metal of your car to sound deaden unwanted structure borne noise! When it comes to sound deadener, & automotive vibration damping, Damplifier can`t be beat

Mobile Audio

Damplifier will help improve your mobile audio system in several ways:

First, and perhaps most obvious, since it is a sound deadener it will kill the vibrations, which will reduce panel distortion and strengthen the area around the speakers. Less vibrations means less unwanted noise and a more stable environment for the speakers to perform in. 
A car with sound deadening will always sound better than a car without sound deadener!

Second, this automotive CLD sound deadener will increase the volume of your music by keeping the acoustical energy in the car rather than letting it escape through the vibrating panels. Volume inside the car increases while nasty panel resonance outside the car is eliminated. Sound deadening makes everything more solid, and sound better.

And  finally, Damplifier can improve your audio system is by reducing unwanted ambient noise like road noise, engine noise & exhaust drone.  Especially when used with our Mass Loaded Vinyl Barrier Luxury Liner Pro. 
When you can quiet down the rest of the car with CLD sound deadening, the stereo has less sonic real estate to fight for, and the perceived volume increases.

To fully reduce road, engine and exhaust noise, we suggest the use of a noise MLV barrier like Luxury Liner Pro on top of your Damplifier sound deadener.

Car Audio Installation | Car Audio Vibration

Thermal Insulation

Damplifier is a thermal insulator much like a coffee thermos. If you put hot liquid in the thermos, it stays hot for longer. If you put ice water inside, the ice takes longer to melt. Sound deadening and vibration damping is only one aspect Damplifier is used for in automobiles!

Damplifier is not only a awesome CLD sound deadener, but it is also a very solid thermal insulator. Damplifier helps reduce automobile heat in several ways.

First, anything you place between the source of the heat, and the passengers will provide some thermal insulation to some extent.

Second, since Damplifier is a CLD sound deadener it has a thick foil layer which acts as a thermal insulation that dissipates heat by increasing the surface area, allowing for heat reduction.

Third, the butyl layer on this CLD vibration damper slows down any remaining heat on its way in to the cabin of the car. The longer it takes the heat to get to you, the more comfortable stay.

This is basically what Damplifier can do for your car. With a couple layers of Damplifier installed, the outside environment has less effect on the internal temperatures of the car.

For the next level of thermal insulation and heat control, add a layer of Heatwave or Heatwave Pro on top of your final layer of Damplifier.

If you want the ultimate in heat rejection, add a layer of Luxury Liner Pro on top of your final layer of Damplifier.


What is the difference between Damplifier Pro and Damplifier CLD vibration damping mats??
Damplifier and Damplifier Pro are the same basic automotive CLD sound deadener mats in terms of product quality, but Damplifier Pro has a total thickness that is twice as thick as our regular automotive vibration mat Damplifier.
The foil on both of our automotive sound deadeners is the same; both 6.5 mils thick. The only difference between the two products is the total thickness of the adhesive.

What makes your automotive sound deadening mat Damplifier, different from asphalt roofing products or sound deadeners that come rolled up?
We only produce automotive sound damping mats that are designed for cars. Unlike roofing tapes, or other products that come on rolls, our automotive sound deadeners mats use only butyl binders with no asphalt filler. Our vibration dampers are odorless, non toxic & designed by expert adhesive formulators to reduce automotive noise and vibrations, not by roofing tape companies.

The foil on our CLD damping mat Damplifier is more than 3 times as thick than that of most roofing products and it will never melt off and cause you any headache.

How much CLD sound deadening do I need to use in my car to properly sound deaden the vibrations?
When it comes to automotive sound deadener and CLD vibration damping mats. more is always better, to a certain point. Covering the flat panels of your cars interior sheet metal panels with as little as 25 percent will help reduce harmonic distortion in the cars sheet metal, however in many cases, as much as 50 or 100 percent  CLD sound deadening coverage might be required, depending on the intensity of the audio system or how loud the road noise, engine noise and exhaust drone is. 
Applying a MLV noise barrier like our Luxury Liner or Luxury Liner Pro on top of your CLD sound deadener will more that triple the sound deadening results from your CLD Damplifier application.

Why does Damplifier Pro not come on a roll like your less expensive Sound deadening competition mats do?
Here is an industry secret. Products that come on rolls are roof tapes relabeled as CLD sound deadener mats. There is not a sound deadening manufacturer in the industry that puts CLD constraint layer dampers on a roll. Real sound deadening vibration damper mats will always come in sheets. If it is on a roll, it is not designed as a sound deadener. It came from a roofing manufacturer and was not designed to dampen vibrations in a car. There is no exception to this rule.

  1. Works well 5 Star Review

    Posted by on 2nd Jul 2015

    I have always used Dynamat extreme and stumbled onto this product. This is lighter and thinner but does just as good of a job. I used this and the Luxury Liner Pro in my cars. The products from Second Skin all seem to be very high quality and do what they say from what I have used so far. I am very impressed.

  2. pretty good stuff 4 Star Review

    Posted by on 22nd Apr 2015

    First deadener I've used. . Pretty easy installation. . Black foil looks nice. . Wish I would've ordered more of the stuff though. I used it for my trunk to shut up my subwoofer trunk rattle. Helps quite a bit for the trunk. . But the rest of the cars plastic rattles now. *sigh, oh well I guess. Good product though.

  3. Works, 3 Star Review

    Posted by on 30th Oct 2014

    Get the PRO line as this is pretty thin, relative to others. Used three brands now, one of which was the "Main" brand.

    Does cut fine and stick great tho.

  4. Great stuff!! Will Buy again soon 5 Star Review

    Posted by on 21st Jul 2014

    I used every kind of sound deadener there is known to man & this stuff is the best by far. Its easy to cut, sticks very very well & the black finish just makes everything look a lot cleaner. Also keeps the temp down in my trunk which is good because it helps keep the amps temp down as-well. No rattles & sounds a lot better, shipping was super quick also. I will be using this stuff in all of my future projects from here on out.

  5. Love this stuff 5 Star Review

    Posted by on 23rd Jun 2014

    I've used about every product out there on my restorations and hot rods over the years, with Brown Bread being the last product I had purchased.

    I find the black matte much easier to work with and hide on the floor pans, and it being even more sticky than other products that often required heat when rolling. Works amazing well.

  6. Worth the money! Great value!! 5 Star Review

    Posted by on 27th Feb 2013

    I could not be more impressed. I applied it to the doors of my 1996 Ford Bronco and it went from a tin can to a solid thump.

  7. A Great Product A + all the way 5 Star Review

    Posted by on 20th Feb 2013

    We used the product in a vehicle that we are building. It when down like a dream, just peel & stick,have used other brands before but this is the best that we've worked with yet. Will be telling everyone about it & buying more for other projects. GREAT JOB , AND GREAT SERVICE

  8. Excellent added touch 5 Star Review

    Posted by on 15th Feb 2013

    This product is simple to install, well made and a must for insulating your vehicle prior to installing your stereo system.

  9. I will be ordering more! A+ 5 Star Review

    Hey Guys! I recently purchased Rattle Pad, Overkill, and Damplifier, and wanted to thank you for your help. I heard from my friends, that you guys were the best, and I always want to have the best for my car. There has been nothing but good reviews from anyone who has ever dealt with Second Skin Audio. The customer service is excellent. And the forum was very helpful in finding out great tips and tricks. Also, Anthony is a great guy! All the products worked wonders for my application. Damplifier was very easy to install, just peel off the back paper on stick it on. Damplifier is a no-brainer, and I will be ordering more! A+

  10. OMG! This stuff is amazing! 5 Star Review

    Posted by on 6th Nov 2012

    OMG! This stuff is amazing! Huge difference. I put Damplifier in my doors and vents. I used Damplifier Pro on my firewall and floors. Then I put Overkill on my firewall and floors. My restoration sounds like a brand new car. I'm telling all my car buddies to buy SecondSkin products. Thanks SecondSkin!
