    Hello all!
    I've done some searches for where to use sound deadener, and it seems like alot of people use it on the outside door skin as well as the inside. My question is- If using on the inside, how and where should I put it? I have an access cab 08 model. One more thing- The back doors seem to rattle alot, and its starting to piss me off!
    Thanks for all your help!

    Adam,

    Deadening is a lot like frosting a cake. The bare cake on it's own is fine in it's own right but could be made better with some frosting work. If I asked you how much frosting you thought would be "enough" for a cake do you think your answer would be the same as someone else?

    The one thing to remember is that 25% coverage in the middle of a panel will get you close to 75% of the results. That's a significant statement so think that over. That being said, the placement is very important when considering HOW to deaden. Corrugated metal and plastic is very stiff by geometry and needs almost no deadening work. The broad, flat panels need the most since they're weak and resonant by design.

    I always say it and I'm sure y'all are sick of hearing it but use the tap test. Hit it and listen to the sound it makes. If it's resonant throw some deadener on the spot. Then hit it and listen for the change. If you're satisfied then you're done. If not, add more.

    GREAT answer! I'm no audiophile, at least not anymore. I plan on running an amp to the front speakers and the one rear sub, and leaving the rear doors unpowered except for the head unit.
    Thanks alot!

    Might want to consider skipping the rear doors entirely. Just adds complexity to the install and doesn't really add anything to the sound, especially in an AC.

    To me it seems the order of resonance and rattle chasing is
    doors
    rear wall
    A and B pillars
    overhead console
    stuff in the dash
    roof
    floor

    just based on my own observance.


    Also, I followed the example of RAAMMat to seal the inner/outer layer. I added deadener to the inner layer, then I had some thin sheet metal (I think it was roof flashing) and a rivet gun, and I covered all the holes in the door before adding a sheet of deadener, then ensolite.
