Take off the barrier and just a quick cleaning

Stuff was rather easy to work with, just make sure you have a plan before you peel off the back. Before I started I tuned my Alpine and my mp3 to the most damn bass I have,( still stock speakers but those are coming too) ...anyways it vibrates quite a bit. Turned it on and did the same thing after I put the panel back, there is a noticeable difference. Cant wait to see how itll sound with all the doors and the new speakers

 

Ohh dude.

The point of Dynamat is to seal off the door chamber from the interior, and the exterior..."To keep the outside out, and the inside in".

All those holes are just going to push the sound right through it like it wasn't even there, and not help the speaker create a chamber, or cut down on exterior noise (Yeah, maybe it'll cut down on a vibration or two if anything loose before is now "stuck".) The only holes cut should be for the speaker and wires, and even then, you should make sure the speaker rim is gasketed or foamed and the wire holes are capped as tight as possible.

This is a properly Dynamatted door before:






And after:





...Even better if you also put a solid layer on the inside of the exterior panel, pushed through one of the gaps to get it there. The more coverage to help barrier the outside from the inside, the better.

You're heating it up with a heat gun after it's rolled to help it stick and roll out the bubbles easier, right? (Not too much heat, don't want to affect the paint.)

 

The outside I figured id do after, not really making it harder on my self this way, but thats where you are supposed to cover as much as you can, my point after a small amount used was just to say it does seem to silence the vibration from the speaker itself. I agree the best way to silence any outside noise is to have minimal breaks , but even one of decent size negates it. Outside panel will be 2 full sheets completely covered, inside panel just keeps that speaker from banging around everything.

 

which "outside" are you talking about? it loks like you did the outside of the door....I mean, if you did the inside, the dynomat would be in the door panel, right? I mean inside...you would not see it....maybe I've had too many beers (is there such a thing?) but I'm confused....I thought you would use this stuff on the backside of the outer door skin....

 

your typing is still coherent....keep drinking

 

if i start writing like dakkkota then I've had enough....lol...
