I've read decent reviews about "Noico" brand sound deadening from Amazon.

You might also want to consider using some closed cell foam combined with the sound deadening mat.

The deadening mat is better suited to add mass to the metal panels and decrease vibration where as the closed cell foam helps more with wind noise and road hum as opposed to rattling from subs.

Noico works very well. Used it many times. Posted some pics of the rear doors I just did a few pages ago. Done quite a bit of Red in it at this point. Still need to do the roof, hatch, and if the carpet ever needs to come out, the floor pan.

Tip though: Apparently word has gotten out about Noico so the price has about quadrupled on the big packs. So this time instead of ordering my usual 36sqft pack, which has now gone to $220 (used to be $66.00). I ordered 4 of the 10sqft packs which are a much more reasonable $27/ea. :dunno:

But as c-bass mentioned it's mostly for metallic resonance and road noise. A dense foam product would be better for plastic rattles/creaks I would imagine.

What did you do to / for your E53 today??
 

I wouldn’t mind quieting some of the road noise, and plastic creaks and rattles. But, there is no way I am willing to add any weight to my setup.

Would it even matter with how loud that X is anyway. LoL.. The plastic rattling is annoying though. :(

Thanks for the tipper, I'll price out Noico tonight as I've used most of the rest of my Dynamat today on the drivers door. I have to say it sounded noticeably better when I drove it to the store this afternoon. Of course it could have been all in my mind, but the car seemed quite a bit quieter and the tunes sounded fuller, and with deeper base. A door cavity full of Dynamat couldn't hurt. I've got a little left which I plan on using strategically around the hatch tomorrow. I need to pull the plastic trim and troubleshoot a loose rear wiper assembly, which probably has just backed off (bolts?) over the years.

I seem to have fixed the airbag light, which did turn out to be a simple connector issue on the front pax unit. The connector is pretty worn where the side clips engage the airbag female end.

I also think I finally figured out why my pax door makes a '72 pinto level of racket/rattle when I close the door with the window not fully up. It turns out a piece of foam is missing from the pax door that I think cushions the window when the door is closed. The pic below has a circle where the foam is supposed to be, just below the handle carrier and on the structural "beam". I suspect the window can rattle against this area as there is no rear window channel on these cars (same guy who designed the clips I bet).

Unfortunately I didn't put 2 and 2 together until I had buttoned up the pax door and opened up the driver's side door and saw the foam. Next time I open the doors up will be to upgrade the speakers so I'll glue/stick some replacement foam in that area then.

Mine does not have any foam there either, PS or DS. When you hear a crazy door rattle (way worse with windows down or partially), I've found it's usually related to the black clip that goes onto the metal latch being broken or not present. Doors sound like a bank vault if that is latched properly. But if they aren't... door sounds like a bucket of bolts.

Dang.. Sloppy Jalopy, hahaha..

My doors are fine. It’s the headliner lighting thing, the hatch, and seatbelt adjusters. Cruising around town, no biggie.

Highway speeds where certain vibrations come into play (nothing mechanical malfunctioning, just road conditions), or the subwoofer bumpin hard, that’s when the rattles happen. Oh well, I guess at nearly 22 years old it’s expected. Heck, I have a few creaks, and rattles myself. LoL..

These are good tips. My doors make a lot of racket after I had replaced all the regulators a couple of years ago. I will have to open up noisiest one and check this out when I get some free time.

I investigated the problem after I did a regulator on my left/front door. Afterwards it would clank and rattle fiercely. Opened it back up and the black clip had broken. Replaced it and it went back to being rock solid. Then it got even better with the sound deadener treatment.

It's always something my friend. Always something. :D Just do what I do: turn the music up. ;)

I'd love to turn my music up but I can only hear FM (AM doesn't work, CD changer works but only silence and occasional electronic squeal) and the tunes aren't to my liking :D

My doors are pretty good although the driver's front door card is a tad loose.

Replaced my fuel filter and washed it
