Sound dampening part 2 rear of 1st gen extra cab

Be careful

The headliner is fragile

Had to remove
seatbelts
Domelight
Sun visors
Map light and rear view mirror
Rear panel cushion
Rear flip down seats
Speaker panels
Windshield pillar covers

 

I’m getting ready to do this, I have a bunch of Dynamat and I also want to re-cover the headliner in something a little brighter.
Did many of the clips break when you removed the panels?

 

No, as long as you pull gently, you should be fine.

The sun visor clasp is a little difficult to remove, be extra careful with it

 

How much of a difference in noise does this make? I'd like to silence my interior a bit.

 

DId the doors and helps a lot

Might want to start there

Doing the doors might get you the results you want

I have a JL audio 12 W6 and I’m trying to get rid of the rattle .

Plus it’s nice to be able to keep my windows up and not annoy other people with my system

 

I agree, because I've done pretty much everywhere but the doors and the floor. That wasn't by design, it's just how it worked out. I've even installed a $60 Dynamat hoodliner and it made 0 difference. I'm using sound meter to test before and after and so far nothing has worked. I have found that a large portion of the road noises is coming in through the cabin air exhaust and the sound probably bounces around inside the body before getting to your ears.
