Reducing door rattle from speakers..?

[Balleriffic1]

alrite. I am in a quest to find the holy grail solution to stop the crappy door (& window?) rattle in our DSMs due to shoddy manufacturing.

Up to now i have tightened the plastic on the bracket that holds the window next to the speaker, and doused the interior door panel with Great Stuff liquid foam (the back part of the panel of course ). The foam has done wonders for my door. But i have also noticed that this problem is not simply due to the empty space between the plastic panel and the door frame (Unfortunately, i think this only applies to DSMs and a few other cars, as I've opened up both my parent's Sienna and Camry and seen that the toy-yoda guys werent playing around when i saw barely any spaces between the panels and the frame, mostly soft plastic and foam was between it, and their solid as rocks). Anywho, I played my speaker with the panel off and noticed that alot if not most of the culprit is the actual metal frame of the door (the one that separates us from the window).

I am not an audio expert, but i do know that speakers produce air pressure, and many a sub woofer enclusure does have holes as air outlets. Hopefully our DSMs have this problem not due to shoddy welding, but the air pressure produced by the back of our speakers is richoceting off the back of our metal frames and making it bang. As possible alternatives im considering either getting a small tupperware bucket or rigging sum fiberglass and use it as a custom enclosure for our speakers, insulating it, and creating and air outlet so the pressure can safely exit thru the panel and to the car interior itself.

If anyone has some insight, please share ur knowledge, experience, etc. I don't care if it supports me or disproves me, I'm just looking to have clean sounding panels, as all of us do

i had this prob when i blew my stock speakers out cuz i was tryin 2 bumb 2 much bass out of them. so i got alpine type S. spearks for the front and back and i noticed the rattleing . i tighted every thing down and every thing and i can still here a lil rattle . it went away after i got my type R subs cuz then i didnt need the bass in my speakers so i turned the bass off the speakers and only had them in my subs and bamn no rattle

haha when i had my sub in...i couldn't hear all the rattles because the bass was nice and loud...but i don't have my sub in right now and all i hear are door rattles....ive also done a wlk around my car with music playing....and the outside panels rattle too! i think its time for a little bitta dynamat and some fiberglass enclosures for my front speakers.
i have infinity kappas up front and they can pound all day long...2 6.5 inchers almost have the same surface area of a 10 inch sub anyways....well closer to a 9 inch sub...so i'm goin to make a sealed enclosure tuned to a midbass frequency(around 125 hz) and that should clean it up alot!. i will also be going 3 way system up front, 6x9's in the back and probably no subs, since i can get more than enough bass out of the 6x9's and 6.5's. the 6x9s will be tuned to a lower frequency to compensate for the sub and fed some decent power.
i'll tell everyone how it goes...should be a fun project.
and for your original question(sorry to bable on) an enclosure for you front speakers will help alot and make them sound better, but a properly tuned enclosure would make them sound even better!
then slap some dynamat on the metal behind the door panels(this stuff works wonders) and you should be set!

I agree and did the same thing as kronic.......leave the bass for the subs, use your fronts as highs and rear 6/9's as mids, that will cure the rattle, did for me.....

Have you tried the dynamat on the metal frame or know anyone who has? my great stuff on the plastic panel has done wonders for deep, steady bass; but when im playing sumthing that uses bass as a beat i can still hear sum rattle. Another thing is that i do not have the plastic 6.5 mount adapter for my speakers, i custom made mine out of 1/4 plywood since i have boston acoustics 6.5 oversized (holes dont align). Is this good or bad for the rattle?

I am not looking to make the doors rattle less, i just dont want them to rattle at all
