Dynamat the Doors........any suggestions?

[davidiiiii]

I think I must be the only gen 3 owner that has doors that rattle with the bass of their music. I haven't heard anyone really mention it before. Of course the rest of the car rattles like crazy, but that is a different story.

Has anyone used Dynamat on their Gen 3 yet? I haven't done one thing to the stereo to improve sound, however I want to be able to listen to the JBL system without the annoyance of any base rattling the passenger door, and the rear drivers side door. I can't imagine much would need to be used, but then again I've never had experience with it before.

Is it easy to take apart the doors? I got quoted $50 an hr just to look at it and to do any work with an estimated 4 hrs from a local audio shop. I'd rather just grab the stuff off E-bay and do it myself, however I'm scared to do something to my new car that I don't know how to do. Should I just do inside the plastic panel around where the speakers are? Or the whole door? Will it even improve the sound?

I installed Dynamat in my Gen II, but haven't done the Gen III yet. I probably installed more than I needed--really way too much. Since the goal is to prevent panel reverberation, less than complete coverage of the door skin is probably fine.

The one thing I'd do on my next job is make use of a door panel removal tool, to prevent breaking any of the plastic attachment pieces. It really wasn't that hard to do, even in the doors, and I did considerably more than that. I'd say the most noticeable improvement was indeed from the doors, and not the trunk, under the rear seat, under the floor mats, etc.

To even make it worth your time I would do the entire door skin (the inside of the metal that faces outside if that makes sense) and do the door frame (the part that is exposed when you remove the door panel).

Your best bet is to isolate the door rattle first and make sure it is not something silly like plastic parts rattling. Those can be isolated eaisly and do not require sound deadening material which will save you big bucks.

You can play a bass CD with test tones and just have the specific notes that cause rattle play on repeat while you search the car for vibration. I'm sure you can download such tones for free somewhere.

I had my 06 oil undercoated a few weeks ago
the other day I was installing q-mats and as I was opening the passenger door
up I found the interior panels of the door all oily:
My experience with door interiors is you have to use heat and pressure to get a good bond or it won't take long before the window starts getting interfered with by the sound deadening mats bouncing around in the door cavity
So now my question
Does anyone know of something I can spray on the interior panels of the door(oil smeared) that will stick and deaden the door panel ?
Not to much of a threadjack

Can you clean the panel surface with acetone or your degreaser of choice?

The vibration behind me in the back door is pretty random, and almost not existent. The main rattle comes from the passanger front door. When it is vibrating, if I pull slightly on the cup holder/storage cup on the passenger side, the rattles go away completely. I'm sure it's an easy fit, but regardless it's going to take getting inside the door. I figured I would use the dynamat to improve the sound experience along with adding mass to the weightless plastic on the doors...assuming it even will help the sound.

I don't know I would even bother putting on the plastics. Since you can eliminate the noise by pulling the door panel away from the door you lucked out and it is indeed an easy fix. Just add some material (silicone comes to mind) between the panels and you're golden.

I have yet to take apart a 2010 so I apologize for not being able to help further.

Probably a good idea. I have really no interest in quieting the car down, so dynamat could just be wasteful. Now if only I knew how to pull those doors apart. I'm not the adventurous kind when it comes to expensive things

2 screws - one behind the opening handle, and one use the rubber "mat" in the closing handle. Start popping the clips around the bottom of the panel. it's easy.

Thank You, It'll make more sense of where you are referring to when I try and attempt the door removal. Same for the rear doors as well?
