Second Skin Damplifer Pro FTW!!!

[w87will]

I'd like to thank ANT and Second Skin Audio for making such great products and also giving them away for free :) since I won a door pack (13 sq. Ft.) of Damplifer Pro from a promotion giveaway over at Stevemeadedesigns.com

I used only Three of Six sheets to do both of my back doors. I have another companies product on my front doors from awhile ago but will be adding some Damplifier pro to them as well.

The Damplifer Pro is GREAT!! Thick Stuff (total thickness = 80 mils) and Sticks to the door really well.

This is what arrived at my door!

Didn't get a roller with it, but I guess you have to purchase that separately...Good thing my brother had one :)

Heres the door with the panel off.

Before I put the damplifer on I removed all the wires and wiped the metal down with denatured alcohol.

It was pretty dang hot outside so I wasn't thrilled to be outside doing this, but I hurried and got it done, I dont think I did to bad of a job. I will DEFINITELY be purchasing more of this product in the future!!

Go here to buy some!! >>> www.secondskinaudio.com

did you take off any previous sound deadning before you took those shots?

[Matt]

Nice Will!

I also have the the d-pro on my front doors... outstanding product!!

Just FYI -- Ant (Anthony) is the owner of www.DIYmobileaudio.com

[w87will]

Dylan- there was no previous deadning on those back doors, just bare metal.

Matt- It is outstanding! I did not know he owned DIY....Pretty cool. I dont think Ive actually looked at the site haha, but I will now. Thanks.

It's 95% sound quality guys on there, but they know there shit and are usually very helpful (i.e. not cocky asshats). Some insane builds on there too!

[Dylans3960ccs]

wow that's crazy, I always thought it was quiet and it is especially for having no sound proofing!

did you do the front doors too?

tell us how much quiter it is :thumbsup:

[w87will]

My front doors have Dynamat on them from awhile ago. Its much better with the sound deadning on them though.

It almost completely reduces any kind of rattles if you have a system and it also just makes the doors seem more solid when you shut them instead of hearing the metal shake around.

[Dylans3960ccs]

Oh, I'd like that.

my jeep does make a strange rattle randomly, but I think it's coming from the dash-board, could this stuff fix it?

[w87will]

If your rattle under the dash is metal haha. If you look through their site they have acouple other products to reduce vibration/noise/heat for other areas of your vehicle also.

[Dylans3960ccs]

Ummm I knew it'd be a little serious lol.

It's nice to know they make good stuff cuz I've been wanting to put something inbetween the exaust and intake manifolds to cut down on the heat making it into the motor.

[Chaoul1]

How much is it to cover 4 doors?

[w87will]

The door pack has 13 sq ft and comes with 8 sheets that measure 12" x 20". I was able to do the outside and inside of both back doors with 5 sheets. So I'd say one door pack could do all four doors if you just did the outside part of them.

Door pack is $59.87 plus shipping.

[jeeppro]

Stuff works great

Are those last pix of it completed, or did you also do the large holes too? I did mine so they are completely covered solid. I also installed an 8"x8" piece of egg crate foam on the inner doors directly behind the speakers to cut down on standing waves. Did you put the stock covering back on too, I think it gives it that much more soundproofing. I ended up useing the stock baffle to cover the back of the speakers for water protection.

IMO soundproofing the doors with additional materials def makes a difference. Now on the highways I dont hear any noise from the doors, only from the rear floor are and from the front firewall/windshield are. Im doing the underside of the hood next, see where that gets me.

[TimmyB]

And why do you have two metal handle things on your door, one for the door lock, but whats the other one for?

[TimmyB]

Here's mine done with just a simple peel n stick rubber based adhesive membrane.

http://i276.photobucket.com/albums/kk37/tdiglar78/DSC01707.jpg

I sealed the panel so good that when I cranked the system up there was alot of air moving in and out from the small cutout for the door lock knob. I had to add more membrane there, but had to leave clearance so the knob will still go up and down.

[w87will]

Thats them finished. I wasn't going to waste a sheet of it to just cover up a hole...the hole doesn't vibrate :), I can get other materials for that. But I think its fine how it is. I really didn't want to cover up my bolts for the window regulators also since I will have to replace them so I went around them and just did the main parts that would make any type of vibration.

Maybe sometime down the road Ill get some Over Kill or Over Kill pro from Second Skin for those holes and the rest of the door.

The bars are for the lock and the handle to open the door.

[HEMIBeast]

Nice job fellas!!

The point to doing the doors is to cover all the holes to make it like an enclosure for the speaker, like a box for a sub. If you covered that large hole you will notice less road noise and less speaker distortion at higher volume. I have enough membrane that I could use it over the entire doors, but I have seen people use plexi glass or even 1/4" plywood cut to the size of the opening, slightly larger to overlap over the metal then seal the edges with the membrane. I noticed a big difference by completely covering the door panels. Just google dynamat on doors and you will see the door panels completely covered and sealed off. Kinda pointless to leave that big hole open IMO.

Good reading to get an idea what can be achieved by soundproofing:

[Micallef]

looking good will, i was thinking of doing the same but never got around too it haha

[w87will]

You should find some time to get around to it :)

[TimmyB]

When I first installed my system I would crank it to about 46 on the stereo, now after doing my doors, cargo area, and almost done my hood I notice im only turning my stereo to about 40 and it sounds just as loud. To me that is def a very big difference.

[robpp]

it all makes sense.

what about the weather barrier and that sticky glue stuff. do you put all that back?

this stuff: dont you need that to keep the weather out?

I'm not entirely convinced that the weather barrier serves a real purpose. What is it really keeping out? I understand water seeps down, but it's not like a running faucet, more like a drop here and there.

If you seal your doors with the deadner, then this effectively is the same affect as the weather guard.

[robpp]

thanks Matt.

[Matt]

thanks Matt.

Anytime Rob! And you only seal part of the door or use a little deadner here and there, you could always replace the weather skin back on top of the deadner or retrofit a portion of it back to cover the exposed areas.

[w87will]

Ive never put mine back on. If I could find some for sale though I probably would just to make it look cleaner.

Now Second Skin is offering their Damplifer Pro with a Black foil backing instead of the reflective one they have had. It also supposed to be alittle thicker than the reflective foil but they are keeping the price the same. I love it.....I need some of that.

[TimmyB]

I re-installed that stock panel. When I did my doors I actually cut out the part of it that goes over the top of the speaker in the back and mounted it in there before the speaker, to keep any water from running down getting on the speaker. And the stock panel does do a decent job of sealing the holes in the doors acting like an enclosure. Helps with midbass and speaker distortion. From removing it the black adhesive was in pretty bad shape so I used more peel n stick membrane to seal the edges of it when putting it back. Why not put it back, its just that much extra sound proofing IMO.

Same here.

I would not anoint the stock paper thin plastic cover any sort of sound deadner or door sealer. The idea of sealing the doors is to separate the front wave from the back wave; the black plastic garbage bag does not come close to doing this.

Nice work Will and Timmy! :thumb:

Would this benefit my stock Infinity system noticeably or would it only be worth it when I get round to upgrading all the speakers and amp?

Hmm, good question, as in im thinking what to save up for first, sound deadning or speakers. I'd go with speakers and amps. But then again I havent heard the Infinity system so im basing it on my stock paper speakers, which I almost want to say the Infinity isnt really that much better as opposed to good aftermarket speakers. To be honest I am happy with just my front componant speakers, 6.5 mid and tweeter mounted side by side in the door 6x9 opening. Hardly a difference having speakers in the rear doors EXCEPT for the passengers back there. I deleted my dash speakers alltogether. The imaging is perfect, sounds like the vocals are right up on the dash, I dont really fully understand how it could be, but it is. And as stated before you dont need to deaden the whole door, just the holes, so you can make a sheet of it go along way with good placement. I did alot just because I have alot I got for free.

Like i said previously, before doing all this sound proofing/deadening I would turn my volume up to 46 (where I have my amp gains set to clip) and now im not going past 40 because its so loud.

[TimmyB]

Same here.

Paper thin??? My stock cover is pretty dam thick, prob 50-70 mills.

If anyone still just has the stock plastic on the interior door try turning the radio up full and put your hand over the opening where the door lock knob is, I bet you will feel alot of air moving from it.

Wow, yeah, mine was really thin.
