Dynamat the Cab......

[72SWBURG]

Has anyone put dynamat in the cab of their 67-72 c10's?? If so, where?? and did it make that big of difference??

Thanks
Brett

It makes a huge difference. As for "where" that is debatable. What do you want it for? If it is to quiet the cab, put it everywhere basically. If you want to quiet rattles, I just ran a strip on the inside of the door panel.

I used Peel and Seal. Not as good for sure, but it works well enough for me.

I want to quiet the cab mainly... This pickup doesn't have any rattles (believe it or not).... I was thinking headliner, door panels, from back window to firewall...

You can never over-do dynomat... I havent done my C10 yet but I plan on doing everything possible. If you have the cash.... do it ALL.

I have an 08 tundra crewmax that I put 2 12"s in and I took the time to dynomat everything. All 4 doors, floor, roof, back wall, and anything else I could cover. I use-to work for a car stereo place a while back and I got hooked on dynomat.... Im a firm believer in it. Its worth taking the time and cash to do it right.

If youre wanting to get the inside of the cab quiet dont just do layer after layer of peel n seal/dynamat or the like. What you wanna do is use a mass loading vinyl. Read a little over this website www.sounddeadenershowdown.com, layers upon layers of sound deadener to reduce noise is really an outdated idea as well as expensive.

Over my peel and seal, I used some industrial rubber foam mat (almost a 1/2" thick) then carpet. The inside of my truck is so quiet, you almost don't know it's running.





I got the mat from a carpet store in town. I called them looking for something, he asked what it was for and was excited to help (he has a '55 Chevy truck). He gave me enough to cover everything and because it wasn't enough for anything he does, he just gave it to me.

Thanks! I hope to get my wheel this week, repaint the dash (didn't like the first color), paint the rest of the cab to match and get ready to install some speakers.

Still fighting with myself on the amp(s) and subs. I change my mind daily at this rate. I think it will come down to what is on the market when I have the cash available. Had I pulled the trigger on a pair of old school Planet Audio tube amps a few weeks ago, this would not be an issue today.

The other issue is NOBODY has shallow mount subs mounted to hear in person. The Kenwoods got the best overall review and the price is right. But I want to hear them first.

My steering wheel should be on the way, I'm stoked. I have a feeling it is going to be as much work (if not more) than the seats were, but if it works, oh man...

Still need to locate a horn button, but I've been looking for one of those almost as long as I was looking for the wheel.

Apply Dynamat to everything that wont be visible! Inside doors, firewall, back wall, if you can reach it stick it on. Dont leave gaps, and tape the seams. If you dont tape it, it will deposit gooey black nasty on everything it touches.

I shot mine with Al's liner, then dyna mat. Next truck I do will be shot with lizard skin then dyna mat, for better insulation.

The stuff is not cheap, but well worth it.

Damn, I learned that the hard way. Good thing I will be pulling it all back apart when I swap the cab to the new frame.

Dynamat everywhere. Especially use it on the single layer steel. The inside of a truck cab is like a hollow drum. The aluminum tape home depot sells works great for the dynamat seam. Just be careful with the tape. Once its stuck down dont plan on taking it off without tearing stuff up.

I used 50 sq ft of FatMat in the cab of my 69.

[66GTO66C10]

Fat Mat is the way to go. 1/2 the cost of Dynamat and performs great!

So, if you used 50 square feet for a regular cab then I will need a 100 square feet for my crew cab? Does that sound right? I want to cover it just like yours.

Thanks for the help!

[66GTO66C10]

100 square feet will cover your crew cab and inside your doors.

Good luck!

I went to Home Depot (in the roofing section) bought some butyl rubber backed with aluminum--it already had peel and stick adhesive on it, cost about $1.25 per sq foot then topped it off with closed cell foam insulation that had adhesive and aluminum backing, my truck is as quiet as a church mouse and it does not go dumb dumb dumb......cost $2.50 per sq ft total.

The insulation was for duct work and the butyl rubber aluminum backed material was for roof repairs around vents.....it worked great and cost a whole lot less.


we even did the inside of the doors

I've never used the stuff, but I've heard the smell is bad...

[kieth]

It has no smell, it is the same stuff that they use in dynamat.....butyl rubber and aluminum....it really quieted things down. Kieth

Mine had a little smell when I first had it in the cab before I put anything on top, but it was right after I did it. My cab got hot (portland hot, not Phoenix hot) and I didn't notice an odor.

I have a mat and carpet in now and don't smell a thing. My cab is dead quiet now, it's awesome.

I planned to put down dynamat to improve the engine rattle and speakers sound. I am curious if you can put rhino liner down on top of dynamat or is there a better way to get the benefit of sound proofing and the muddy boots and floor protection you get from rhino liner?

If you're looking to spray something like a Rhino liner down, I'd try the lizard skin product...it looks just like rhino liner after sprayed and also sound deadens so there'd be no need for a matt product. They have a thermo one too I believe. You can paint over it as well after you're done...
