Sound deadening in doors?

lol that is except why I ditched the bmw.. it had left me stranded a few times..

How easy is it to get under the front carpet? Remove seats and lift the carpet or is there other stuff that needs to be pulled?

I figure the transmission tunnel is a good source of noise too?

 

I did this recently and didn’t go overboard… just a few sections on inside of door panel and exterior door panel. I may do more if I notice more vibration after new speakers are in. I used Resonix

 

Remove seats and you have access to the entire carpet. You can then pull the parts to have access underneath it. Keep an eye on which rivet, plastic tab, bolts goes where.
You can do the entire car floor if you like but I am not sure I have that patience or if the effort equals the resultant benefit.
You are chasing unicorns if you are looking to completely quiten a 4runner.

 

If not, remove the vapor barrier and add it to the inside of the outside door panel. That's were all the vibrations come from. And you door will close like a Rolls Royce.

 

I just had someone comment on how solid the doors sounded. I have only done my doors, and was instantly satisfied with just the improvement when closing the door. I took on the project to put some backing behind my speakers when I installed new ones. Worth my time.

 

Agreed.

I thinkthere was a website long ago called

Sounddeadenershowdown .. anyways he tested that you will get most of your resonance in panel dissapear once you cover an area of 25%

Anything over that adds weight and money

 

Why did you only cover the 4-5 areas of that door? Is there some specific reason? I’m curious what the 4-5 strips you got there actually do?

 

To stop speaker vibration and resonance.
