I have ordered a bulk pack of Dynamat insulation I was wondering what parts of the front and back doors do I apply this to, whether the outer skin or just the panel where the the speakers fit

Did you buy extreme or regular? The front doors are pretty easy to work on. I put the biggest piece I could fit onto the spots of the outside skin I could reach being careful not to get anywhere close to window travel areas. Just peel back the vapour barrier where needed, apply, and then refix the vapour barrier overtop. Careful in the cold, the vapour barrier can tear if you aren't careful. Try to grab the butyl rubber seal through the vapour barrier when pulling so the seal comes off with the barrier rather than the vapour barrier coming off the seal. As for the inside skin, it was quite easy on the fronts to do a lot.

If you have lots left over, apply it to the inside of the trim panels too, they are quite squeeky.

If any GTA / southwestern Ontario members are interested in sound deadening, lmk, I've been chatting with the owner of Raammat about doing a group buy.

Cheers

Thanks for your help. I have purchased a bulk pack of Dynamat Extreme quiet expensive over here $208 plus freight. I was hoping the 9 sheets would be enough to do the outer skin as well on all four doors, not worried about rear parcel shelf. Just checking, do you need to re-apply vapour barrier if you have Dynamat completely covering inner panel of the door ?.
Over here it's summer so I was hoping the warmer weather would make it easier to install.
Do your doors sound more solid when you close them now you have Dynamat installed. I noticed the up-dated 2010 Forte over here has much better sound proofing or something on the doors and trunk lid , as they were quiet heavy and shut with a nice solid thud. Hope my efforts with the Dynamat has the same effect

You only need the vapour barrier if you have not totally covered the inner skin. Just an FYI, it's not a good idea to seal the insideby just adding a huge sheet and having bare dynamat cover the holes, you should really add a substructure for the mat to affix to.

Rick's Installation Guide scroll down it's in the center.
