DOORS
****************************************
So I started with the doors. I got as many cans as I could of Duplicolor�s Sound Eliminator from AutoZone. It was not a High stock item.
I coated the inside of the outer door skins. Here is a pic of a stock inner door...
Now mine all coated...
It was waterproof, so I did not have to worry about it dissolving if rainwater found its way in! I did have to be careful to protect the windows and all the gears and components. I used newspapers to wrap around components, but soon learned it does not have the overspray characteristics of spray paint. So I only had to really protect from direct spray and dripping. This made the second door much easier.
I coated every bit of the inner door I could get too.
Then it was onto the inner door skin (part under the door panel) I did not want to make a mess here since the door panels were directly mounting to the surface. So here I used Dynamat.
I was quite generous as you see, but it worked!
I used some high grade clear sticky backed plastic from Delta to seal off the door from moisture. My stock liner plastic had been shreaded by the dealer.
I placed a great deal directly b/w the speaker and its mounting point. Its hard to see due to the waterproof speaker baffle I installed to protect the door speakers!
Next I used subwoofer box carpet and lined the inside of the door panels before they were installed.
Will get more into this later on in the site...

AIR PRESSURE RELIEF VENTS
****************************************
With that done I still was getting some buzzing...
One very large annoyance was the plastic air pressure relief vents in the door jams.
They have rubber on the backside that flap as air passes through.
Normally I never noticed, but with a decent stereo system and the other noise gone, they flap each time the bass hits! So I pulled off the rubber with a pair of pliers and put foam on the backside of the plastic where it touched the body. The buzzing and flapping noise was finally gone!
****************************************
DASH
****************************************
Time to work on the dash. I had noticed it tended to vibrate and had its own rattles while driving...
I removed the dash pad. I Dynamated any plastic under it figuring the Sound Eliminator would be way too messy here!
I lined the dash pad w/ sub box carpet.
I even took out the gauge cover and added some foam b/w the plastic pieces where they tended to buzz.
Here it as I am pressing it in with the install of the gauge cluster cover.
I then attacked the panels under the dash right at you knees
and above you feet... They all received a sub box carpet lining.
This is what GM had there instead...glued with hot glue that let go...
When I put the dash back together with all the soundproofing, there was such a difference.
In fact, it was such a huge difference, that I decided to do the rest of the car...
