Finished up the Dynamat project, thoughts?, Includes semi-big pics Options

[GotToyota]

I finished up my small Dynamat project today after school. I did my doors a few weeks ago, as well as parts of my hatch, but went ahead and got some more to finish it up.



The doors were already finished, but I went back and double-layered some parts that really needed it.



Same goes for the other door.



And what I'm most proud of, that did the most, in my opinion, was the door panels. Both were the same so I didn't bother to take pics of both.

I didn't catch a pic of the hatch, I forgot I needed to take a picture as it was already re-assembled. But I'd like thoughts on how I placed the Dynamat and such. It sounds fantastic and almost all road noise for the most part is gone and is much quieter on the highway.

smoking macaroni...man i didnt know you can eliminate road noise with that. Now my to-do list is getting longer...

holy added weight batman!

but noise improvement good stuff

Dynamat does not weigh much dan. 100 sqft weighs ~20 lbs total. I weighed it before install.

also on my to do list

but on the far end of it

great job on the placement. wish I could hear how it sounds.

but as far as i understood, dynamat needs to be placed all over, not in pieces,, if my thinking is correct,,,, you messed up, road noise not only comes through the holes of the door panel. it comes through all the entire panel,
correct me if i am wrong

it is VERY cost effective to place in pieces. i've heard both types of installations on doors of a ford explorer and there is little to no difference. thats just my opinion.

nah you dont need to place the entire pannel...but if you look again he patched up the inner pannel and the inside of his outer pannel, the whole door pannel is pretty much covered. Now the boot, the floor, the roof, the firewall.....etc

yes, you are correct...BUT the floor is awsome to do in big peices, and if you want to do multiple layers its nice if you do them the other way so firs - than | then - and that works best.... technically it doesn't weigh much, but look at our car...look how much it weighs... 20 lbs is always a lot....

the panels are ok to do in peices, and quite frankly its benefitial.... you really dont need to put dynamat downn where it doesnt rattle or need it (technically speaking)

exactly. save the stuff for the floor and the roof where the parts aren't shaped too much... and the firewall. if you have an exhaust setup, the trunk is a noise magnet.

Dynamat does two things.

1) Mass damping from its weight. Basically weigh anything down and it will lower its resonance frequency and also increase the energy required to excite it.

2) Blocking from its aluminium foil. This is straight out stopping the sound from going through. (so cover as much surface as possible when you want to achieve this)

so, if you want to use dynamat to its full potential and you are short on cash. Put dynamat in the middle of flat big surfaces such as the outer door which you did not dynamat. The inner metal which you have done is a convoluted surface and mass damping isnt really needed. So you basically are only using it as a blocker and since you did it in pieces, it is not really performing all that well.

The dynamat on the door cards is alright but I can do the same with rubber sheets etc to stop it from resonating for a cheaper but messier option.

I would also suggest covering the access hole. You will be surprised at the difference. use thin mdf. Let me know if you need any other help

i think u guys went too far , when i mentioned the entire panel, i was just talking about the door panel, or i dont know if thats the way it its called,, jajaja i was not trying to say that you have to put dynamat on the floor or the front panel jajaja

So you basically are only using it as a blocker and since you did it in pieces, it is not really performing all that well.
