Sound proofing the cab question

[truck69]

My 69 chevy has a way to go before I start thinking about installing a new radio and such but wondered something. As I drive it now I can't hear my self think as I can hear the road around me and the engine as I drive. When I get to the point where I take out the seats and carpet and put in the sound proofing, how big of difference does that stuff make? Back then I dont think they were thinking about winning a stereo sound off. Any help would be great.

Thanks. Truck69.

I haven't used it in my truck yet (I need a floor to stick it to first....) but I have used it in, my Vette, and believe me, it works! I would reccommend one or two layers of the rubber stuff (Dynamat, Fatmat, Brown Bread, Noisekiller, etc.) and then a layer or a softer deadener on top, such as Dynamat Extremeliner or Brown Bread V-Comp. That would do the floor/firewall. For the doors, I would maybe do the inside of the outer skin, but for sure do the tin behind the door panel, and maybe even the backside of the door panel itself.

^ What Mudder said, makes a HUGE diff.! I didn't use the dynamat or brownbread though, I used a sound deadening kit from one of the vendors (white foam & tarpaper type) and put new carpet over it. One thing to keep in mind (I forgot to do this) is prewire all your wiring for additional subs/amps/speakers if your planning any stereo upgrades under or behind your seat in the future. Doug
