Reducing road noise
I have heard of brown bread and dynamat being used to help deaden the roadnoise in the floors. Is it worth it to put it in the doors as well?
Thanks.

Yup. While the floors get tire and rock chip noise, the doors make good wind echo chambers. Sound insulation between the panel and the inner doors can work wonders, both for noise reduction and stereo speaker sound. Not that you would ever cut doors for speakers.

I plan on doin my floor, firewall, inner doors, backsides of the door panels, and the tin behind the door panel. I hate road noise, and I've used brown bread and I must say it works great!

I had considered lining the inside of my doors with an insulator but I was concerned it would hold moisture. After all those drain holes are in the bottom of the doors for a reason. I do think I will be lining the inside of my door panels before I reinstall them.

I believe most sound deadening products are moisture resistant. I know with things like Dynamat, it's kinda got a tar-like base to it with some kind of plastic or vinyl film on top.
I never heard of brown bread until I came to this forum, so ... I guess I'm kinda dumb as to what it's like. I gaurantee you you won't have moisture buildup using Dynamat inside or outside your vehicle.

I think that brownbread and dynomat are the same thing. I like that brownbread doesnt have any writting on it though.

The cardboard lining that screws to the front cab pillars on the outside in front of the doors can help cut down on wind whistling noise.

I highly recommend Dynamat. I installed their Extreme model everywhere there was metal inside the cab, except the dash itself. On the floor, I also used their Maxliner. It is a lead core foam padded material. I would caution all against using any foam type sound deadening products in the doors as they will hold moisture and condensation. Take it from someone that thought it would be fine since my truck never sees rain and is garage kept. Ever washed your truck? Water and foam inside the doors is a very bad thing! I am replacing both my doors. Keep in mind that not all sound deadoning material is the same. Dynamic Control, the makers of Dynamat, are extremely impressive by continuing to develope better products. The research and developement that they put into their products is amazing.

This is sort of on topic: Here is a article showing how to install sound deadening material in a 60's Chevy pickup:
http://www.classictrucksweb.com/tech...dsc/index.html I saved it from a month or two ago.
