How Much Sound Deadening Do I need?


Recommended Posts

I remember seeing the guy from second skin said you only need 50% coverage on a panel to achieve sufficient results.

I'll admit, half way through sanding that fiberglass in the rain and cold while I was all itchy I was definitely starting to question why i was doing this haha

Thing i disagree with is all these test.

Perfect example the bell test and how a small piece of deadener quiets that bell.

Has anyone ever stopped to thing what frequency that bell dings at?

And thats just it, its a ding, its not a massive amount of pressure from a pair of 15s on a 5,000 watt amp.

Sure maybe that 50 or 30 percent coverage will be great for a simple set of components in your doors that wont flex your doors off the hinges unlike some of the more common ground pounders being built.

So If I plan on putting a single 18, 1500watts, with factory size door speakers, 30- 50% coverage would be enough?

What are you wanting to do with the deadener? If you are just wanting to lower resonance then @25% is probably good enough. If you are looking to reduce flex then you need to add mass in which case you need more coverage.

Does anyone have any experience with Second Skin Spectrum? Is it any good for sound deadening?

My trunk was from SS Alpha Damp that I got for free from "Alpha Damp Giveaway Extravaganza!" with plenty of left-overs.

As for my doors, I used about 14 sq/ft per door of Second Skin Damp Pro.

I also did the inside of my door (behind the speaker area and such):

One final word of caution... do not buy "FatMat". I spent hours removing this stuff from my trunk lid for better deadening:
