Brand: Second Skin Audio-Damplifier Pro
Purchased From: http://www.secondskinaudio.com


Installation: Easy to install
Installation Time: I installed nearly 300 sq. ft. and tore apart the entire car so it took approximately 4 days
Any Installation Tips You Have: Use a tennis ball to force it down instead of a roller. It makes things much quicker. This stuff sticks to anything and is pretty flexible so install goes easy once car is taken apart.

Quality of Part: 10
Product Performance: 10-thickest most effective mat type deadener I've ever used.
Would you Recommend to Others: This product gets my highest recommendation

Second Skin Audio Damplifier Pro and Overkill Pro. Both of these products do what they say and more. I recently purchased 290 sq. ft. of Second Skin Damplifier Pro, and two sheets of overkill pro to use in my front doors. For those that dont know, I now drive a 2008 Pontiac G8 GT. I'm planning on doing some Sound Quality competitions for fun and building it to sound great for my pleasure on long drives with work.

The Second Skin Damplifier Pro is an amazing product. I will list the benefits and advantages I've seen with its use in my car:

1. Heat reduction, in the past I rode with the AC on 63-64 degrees to be comfortable. After completing my installation I now ride with the AC on 72-73 degrees with the same comfort as before. It truly helps fight the heat!!!

2. Noise reduction, this car is built well from the factory and quiet enough for most as is. With the addition of the 2-6 layers of damplifier pro at any given point in the car its virtually silent. When driving you have to wonder if you're really doing 100MPH or sitting still. I can enjoy a live performance of Bon Jovi, the Eagles, or the USACi SQ disc at high speeds in utter silence.

3. Ease of installation, the product is very easy to install. It is sticky enough to adhere to just about anything yet not so sticky/gooey that if you barely touch it down it can't be removed. 15 minutes later though its a pain to remove which means it will stay in the place you put it for years to come! It is also very easy to cut or even tear into smaller pieces to get in those hard to reach spots.

4. No odor, there was literally no odor with this product at all. During the entire installation the only smell I ever smelled was from the headliner glue adhesive I used to install the overkill Pro.

5. Using plenty of damplifier pro in your doors makes one helacious speaker enclosure to house some great mids. It literally sounds like I have subwoofers in the front of my car.

Now, the overkill pro:

1. It does not soak up water. Doors naturally get some moisture and condensation in them, however after riding for several days I found this product is great at resisting water and will not mildew or stink up your car.

2. It helps reduce airborn noise in the door panel yielding a more focus midrange and midbass region for your speakers.

Now for some of the pictures from installation:
2-6 layers at any given point in the car. This is the floorboard covered:

I was very impressed with the products and would recommend them to anyone considering improving the sound in their car, reducing the heat, or just wanting a quieter ride.

So my question is:

Did you put it on a scale before and after? Sound deadener is great, but everything I've ever seen is H_E_A_V_Y. Ridiculously so :(

0.5 lbs/sq. ft is the weight of the Damplifier Pro. I added 288 sq. ft to the car so roughly 145lbs. I don't take this thing to the track. I use it for everyday driving and care more about sound quality and quietness than 1/4 mile times. To each his own.

^Agreed.

Unfortunately I wouldn't be able to do this due to me wanting to race and compete in the future. But, this is a really good idea for some who use it as a DD w/ no racing! I wouldn't imagine this would affect the bumper to bumper warranty would it? Some dealers are real nit-picky when you remove then re-install a part then something goes wrong, I.E. seats, carpet, console, etc.

TRUE! Different strokes for different folks. If we were all the same this world would be a boring place...

The car stereo shop I worked at prior to starting my new job does a fair amount of work for the dealership I purchased my car from. We have a good relationship with them and I would hope that because of that they would be more willing to help. They gave me a good price on the car due to our relationship with them and have provided great service thus far. I look for this to continue.

Do you guys think this might help with the drone if you installed in that plastic bucket we have for a trunk....

It couldn't hurt. I have a lot of experience with materials very similar in helicopters. It works great. We experienced a drop in db SIL by 14 and dba by 10. To guage that, 7 db SIL difference is like half the volume. Even several small pieces over the large areas, i.e. the trunk lid and such, will greatly reduce the sound levels. I commend Hotshoot as this is a lot of work and something you have to take your time with or it would not be worth it in the end.

I was wondering if you could let me know if sporadic placement of second skin regular dampener on just the plasic door panels and on the rear deck is good enough to simply quell vibration?

I have a little bit left over from when I stripped my 08 civic si, but I don't want to to do that much work to this car, just the minimum to get the most bang for my buck.

Also wondering if I need to do the trunk as it feels solid and is already cloth covered...

That is a LOT of sound deadener. I did something like this on my GTO and it is stone-quiet. Personally, 2nd Skin seems too pricey to me, as there are other products that are a better value.
