My soundproofed drivers door.
Here's what I did today after work. I installed Grace Vycor Ultra air and vapor barrier membrane on the inside of the door covering all the holes. I also installed self adhered EPDM roofing membrane on the inside of the outer door, which the EPDM is super thick material and doesnt run when exposed to high heat. The Grace Ultra is a rubber based membrane which also stands up to high temps. I did all my doors this way, and have only the rear passenger left to do. Then start ripping out the seats and carpet and doing the floor boards. Oh, and I wiped the door frame down with a clean cloth then sprayed on 3M adhesive in a spray can I got from Homedepot and let that set up before I applied the peel n stick. The membrane is fully adhered now, after really pressing it on good with my fingers in all the contours or the frame.

The all black material is the EPDM membrane, I added that on the larger holes in the door after several layers of the Grace material for added rigidness. The end product is very stiff with the built up layers and does not move, making the door an "enclosure" for the mids.

Close up view of my JL XR 6.5 components, installed on a 1/2 MDF bracket that fits over the stock 6x9 location. The stereo imaging is great with this set-up, the vocals do sound like they are right in front above the dash. I removed the stock speaker baffle/soundproofing and installed rope caulk on the door frame then reinstalled the baffle part. I installed the MDF bracket set in rope caulk and also set the mid in rope caulk (available at Homedepot in the door weather stripping section).

View of how I ran wires through to the drivers door. I sniped away some of the plastic in the sleeve that fits in the frame. But since this pic I have swapped out wires, and now have two 12 gauge speaker wires running thru the same location, one for my tweeter and one for my mid. My crossover for the drivers side is mounted under the steering wheel on the door that comes down. My passenger crossover is mounted in the kick panel.

I am going to do a complete write-up of my stereo, I think I learned alot from doing it. :thumbsup:

Great work, like the speaker set up too.

Do the WKs not have tweeters in the dash or did you find this was a better location for imaging?

Re: My soundproofed drivers door.
Stock is 6x9in the door and i think 3.5 up in the dash. I copied the idea from the WJ JL Audio upgrade I found online, where they made those brackets. And im actually amazed at how it really does sound like the vocals are coming from the stock dash location. I keep seeing the speaker manufacturers all saying keep the tweets and mids with-in 8 inches of eachother, but then I see everyone mounts them seperate so who knows whats better. But I do like this set-up and sticking with it. I was expecting it to sound like crap, like the vocals were at the floor but it somehow carries up. I guess its the same concept as mounting them in kickpanels at your feet, I dont get how it would possibly sound good but it does.

Re: My soundproofed drivers door.
Ah cool, thanks for the info!

That'd sure make it easier to wire up too. Will bear this in mind when I actually get round to upgrading the speakers/amp in the Jeep.

Re: My soundproofed drivers door.
I think im def adding some weight to the car with my soundproofing. Just by foaming the cargo door frame the thing needs a little push to go up. But the peel n stick membrane doesnt really weight that much, i'd say 2lbs per door. But the result is a sealed enclosure for the mids and so much less road noise.

I had the drivers door panel off earlier and the system cranked looking for air leaks, and the air flow coming from where the door lock knob goes thru the door was alot. I sealed the best I could around that now.

Re: My soundproofed drivers door.
Nice work Timmy!! Looks great!

Sealing those tin cans that Jeep calls a door really makes a difference ugh..?

When you go active (and I know you will, hehe) drop some big/bulky 6.5's in there and you'll swear you'll never need a sub, lol.

Re: My soundproofed drivers door.
have you ever tried using a closed cell foam or the sound dish things behind the speakers. i have the foam in mine, def gives it more punch. the deadening looks really good great job. i used dyno mat in mine i also had to do the ceiling.
