    Recently got ahold of some sound dampening adhesive mats, a few square feet, not much.
    In a double-cab, in which areas would soundproofing have the greatest impact?

    Adhesive mats as in something along the lines of Dynamat? If you only have a few square feet, your best bet would probably be to put it on the doors to help give them that nice solid sound when you close them, and to help a bit with speaker sound. My understanding is the best place to sound proof is on the back "wall" of the truck behind the seats, but you want mass loaded vinyl (MLV) for that type of sound deadening.

    Yes, Dynamat knockoff. Thanks, I'll stick them in the back.

    Dynamat and the like do not actually deaden sound, per se. They damp panel resonances. Around 25% panel coverage will be adequate. The guys that do two layers of that stuff are wasting money and adding unnecessary weight. Like Capt. Obvious said, you want mass loaded vinyl, usually around 1/8" vinyl backing with a 1/4" closed cell foam. Works way better than foil backed elastomeric material.

    Time to make my build page!
    I'm doing my roof this week with Dynamat and Dynaliner. Before, it sounded like I was in a tent made of beer cans when I through the car wash. The roof is the last large area I have yet to work on. The back wall and doors have dynamat. The doors have two layers of dynamat, I know some believe this to be overkill, but two layers gave them a real nice solid sound when closing. Plus, the place that put my components in did the door work. The floor has Dynamat and Dynaliner.

    While doing the roof I have been doing some Google-fu to see what others have done. If I have this correct, Dynamat dampens panel vibration, thus you only really need 25% coverage. Dynaliner is a closed cell rubber which has good thermal insulational properties, and it "deadens" higher frequency sound.

    How much coverage do you need with Dynaliner? I'm rethinking my application of Dynaliner to the floor, with the thought that I should of put a MVL product on the floor. I guess I could just put Dynapad on the floor (on top of the Dynaliner) and then put sticky Dynaliner to the rear wall?

    You want as close to 100% coverage as possible with the MLV. The really hardcore guys will tape seams and everything, because technically, anywhere there is a gap there is a place for noise to get by. For the average schmuck just wanting to quiet the cab down a bit, I would shoot for more or less covering the whole area with it, but "close enough" is good enough.

    Nice work, and thank you for sharing. I will be finishing the roof accordingly! I think I will also put Dynapad on the floor.

    From the drivers seat, sensitive seat of the pants measurement for sure, it sounds like the pillars are a source of noise. I was thinking about running some 3M NVH in there. Does anyone have experience with this stuff? I guess I could also use the acoustic insulation that Old_Skool mentioned.

    http://3mcollision.com/products/sound-deadening/nvh-damping-material-04274.html

    ---- After reading some reviews of the 3M Acoustic Insulation, it sounds like this stuff is the best. The problem, where to find it? Any advice on that Old_Skool?

    This is the amount I bought. This seller is legit and it's ships quick from Beijing. It's the real deal :)

    I also stuffed the cavities of the B and C pillars with what I had left over.

    That link is a click-bait nightmare. Maybe you could post a different one?

    Do you guys do this to basically lessen the road noise from coming in or is it more to amplify the sounds inside(music) to make it sound better? Or both?

    Both, really..... having a luxury car quiet truck is really nice. Not having every panel vibrating and buzzing like a hooptie when playing music is really nice ;)

    Like a hooptie... Good quote.

    Sorry about the link. I run a Mac with Ghostery. I go most places without trouble. I put it in my media and it should be visible now.
