I have an 06 6MT (purchased march of 06) Sedan with 22k miles on it. Everytime I play something with any small amount of real base, the panel vibrates like crazy. I brought it in to the dealer and they responded with what you would expect. So now I have been living with it for 5 months. Anyone else have this problem and know how to solve it.
I can actually reach across and push it in and it will go away temporaraly but it is back within 5 minutes.

Let me know if you have a solution.

 

I have the same problem in my 05 6mt sedan, in both the passenger and drivers side doors, as well as the passenger side b-pillar. I am going to replace the speakers in the car, so while I have the doors apart I'll see if I can find anything to fix it and let you know.

 

if u have ur doors apart u might fix it with some "edead" i think thats the name of it, its like dynomat but ten times better, it should fix ur prob

 

I used felt with an adhesive backing. You can get it pretty cheap at walmart in the crafts section. 2 packs of it should get every nook and cranny in the door.

Make sure you take the time to remove the door tweeter and cushion all the edges of the tweeter and anywhere plastic meets plastic or plastic meets metal.

Although this bought me some piece of mind for about 3 months the rattle has returned so do not take this as the end all solution. This bloody car rattles more than rocks in a can riding on a donkeys *** down a rocky slope.

 

I went up from a 350Z to the G35 hoping to get rid of rattles. This car has 5200 miles on it and it is already starting. I know I may sound like a whiney baby, but for a $34k car, I expect a lot more. Next car may be a boring Lexus, but at least it will not creak, moan, and rattle!

 

On the door when you take it apart just look at the highest point of the metal plate covering the regulator and stuff. Look for an area that has a few marks on it from the door panel touching on it. Just use the double sided felt tape as mentioned above (its what we use) and cover those spots. Line the speaker if you think it rattles but most likely it will be the door. It happens on just abuot every car that comes through here each day. It will take care of that issue but something else may pop up afterwards as usual.

 

i have this exact vibration too on my passenger side ... looks like from b-pillar too.

i thought my speaker was torn or somethin with how bad it can sound sometimes .. realy ghetto.

ill have to look into this.

 

had a similar sound in mine. Ended up being the tweeter speaker was the root of the problem. Was loose and I added some padding behind it to stop it.
