I finally got back to work on this and sound deadened the doors, the weather was about as uncooperative as it can get but my indoor work space is full of other projects and I finally had the roughly 5 hours to do this. When it's cold out and you have to work with plastic a heat gun is a great tool to keep the plastic flexible, cold makes it brittle and likely to crack or tear with pressure applied



To start the door cards each have two screws holding them to the door, they are hidden behind these plastic covers that you can open with a small flat head or similar tool



The other screw is in the door handle and the recession makes it more difficult to pry open using only gentle force, push too hard and you can gouge the plastic or break the tab that hold it down



When you get the covers open, hopefully without breaking them, they stay attached on the one side and don't need to be completely removed



With the screws removed there are just a few pop clips holding the card, I found pulling from the hinge side first worked best and worked my way around the bottom



There is one pop clip in the middle along the bottom that pulled out of the card on every single door, another pesky one is the one in the center of the card between the armrest and the door lever that is easy to forget about



I took the water barrier off with as much of the sealant as I could but the sealant won't really harm anything, taking off the plastic covers on the top left (removed) and bottom left make it much easier to access the door skin



I used the heat gun to warm up the outer skin and the dynamat to promote adhesion, the inside does get some exposure to water so cleaning or at least wiping it down before applying the dynamat will also help



Using the water barrier as a template I cut it's replacement out of the ensolite, it looks like there is some insulating foam in the barrier already but I still prefer replacing it with ensolite



The bracket for the door handle as well as a couple harness clips needed to be removed and reinstalled over the ensolite, the spot for the center pop clip needs to be cleared so it can sit flush and the door card is ready to go back on



Plugging all the electrical connectors back in is simple enough but there is a lot of them, the cables have different size balls on the end so they don't get installed incorrectly but there is a blue mark where the black cable goes to make sure you will at least try to swap them

Found this little guy hiding behind the passenger door card, the free ride is over buddy



I really like the access you get with the covers removed, I was able to use some pretty big strips unlike with the rear hatch



Putting the ensolite on around the edges first and then pressing it into the middle keeps it fitting correctly, there is some slack for it to fit into recessed areas and if it's too tight the door card won't want to fit



The rear doors have great access like the front but the impact bars are diagonal making for some tricky shapes to cover



There's one pop clip on the rear doors that needs to go through the ensolite, the one in the bottom right corner should be cleared like the others so the clip can sit flush



I think I might have the answer to a complaint a lot of HK Outback owners have about the sound being weak in the rear, never seen a woofer so blocked and keep in mind it still has the grille to pass through after this baffle



On the last door I noticed some sprinkles starting to fall while heating up the edge of the card, it's good to keep a bit of distance to spread the heat over a larger area and to avoid possibly melting anything



The rear doors have the same foam in the water barrier and in this pic you can see clearly the indent the door card needs to sit properly, always cut the ensolite a little larger because it won't stretch as well to fill those depressions



Rushing things along to get out of the rain I forgot to put dynamat on the outer skin, feels pretty bad making that mistake



I managed to push through and finish thanks to my huge umbrella courtesy of Subaru, next thing is the floor and I will be waiting for better weather or garage space for that

So...what kind of difference have you noticed?

The only wind noise I hear is through the glass, I'm thinking window tint might help with that. Still a lot of road noise through the floor, drivetrain noise as well. I'm also thinking of getting back into the doors and adding more dynamat around the speakers

Excellent work. I added Hushmat, 3/16" closed cell foam (CCF) and mass loaded vinyl (MLV) on the floors and under the console. I did not remove seats, what a pain. It made a significant difference in road noise. I also did the cargo area and doors as well. Well worth the effort. I made a post about my efforts in the Gen 5 section.

I added hushmat around and behind all my door speakers as well as the rear subwoofer. Seems to make the sound crisper and with more bass.

Thank you
