I have a '02 M3 Convertible and am trying to eliminate AS MUCH road/exterior noise as possible. Should I DYNAMAT everywhere? I'm taking apart the back seat and trunk and well as both doors. What's the best way to go about this?

Should be posted to the e46 section. In general dynamat is not something you want to deal with, it is a mess.
Deadener adds mass to help eliminate vibrations. A closed cell foam barrier will help decouple higher frequency noises (road noises).
Take a look here for info, the owner is pretty knowledgable and helpful:

Honestly, not to be a dick, but you could just get a coupe. If you don't have a hard top, can you get a hard top for it?Comment

You should dynamat the convertible top, that would help a great deal...Comment

Guys...both those last two comments were pointless....i'm trying to soundproof the metal area to drown out exhaust, squeaks, and tire noise....THAT'S ALL! Who in their right mind would Dynamat to convertible top? It wouldn't close anymore or probably something crazy would happen. And why would i convert my convertible to a coupe if I purposely bought a convertible?....ugh...USEFUL comments please!Comment

You are posting a useless question in the wrong section, what answers did you expect to get? The verts have rattles, squeaks, moans, groans, and everything in between; live with it or get a different car. I truly and historically try to give the 'nicest' advice possible, but that's the reality of it. You are working from behind. Its like buying a vert to build into a track car.Comment

ha, you live down the street from me.... but yeah, convertibles are just naturally more noisy, not much you can really do about itComment
-
Buy a hardtop, that might help. As for the interior, gut it and Dynamat extreme every bare spot.Comment

I forgot to enclose it in sarcasm tags. Really OP, you have a convertible. They are noisy, they rattle, and they squeak. You are trying to teach a pig to fly, which will just frustrate you and annoy the pig...Originally posted by enderw88Comment

use sound damping materials like edead, dynamat, or home depot cheap aluminum faced rubberized sealing (just like dynamat but for like roofs or w/e).
Pull your door panels, roll up your windows, place a strip on the outer door shell first (inside the door cavity not outside of the door), then do a large section on your door panel. covering up holes in the door. reattach your door panel,
Pull your back seats, bolsters, and rear panels out, pull your trunk carpets out and any rubberized coverings. the rear shock towers are not going to transmit much vibration as their structure gives them good damping properties but it transmits the vibrations to the surrounding metal, lay up strips where you can, any thin single walled piece of metal can be covered. the floor usually has some factory damping but you can always add more around it. pull your trunk carpet off, put some inside the trunk voids, then a big strip where the carpet goes then reattach your carpet. Get some anti-vibration grommets for your license plate (simple o-ring should suffice). I wouldn't mess with putting anything on the gas door cover, that's just overkill. If you're willing to pull your entire seats/carpet/ and center console out, you could dynamat the entire floor up the side of the rockerpanels, and up over the transmission/driveshaft hump in the middle.
Doing all that would seriously reduce your road noise. the convertible top doesn't really have anything to do with road noise. it has a lot to do with WIND noise but unless you're in a tunnel, you have nothing bouncing the sound back down through your roof. There is of course ambient road noise that will be more noticeable in your vert vs a coupe but I honestly think its such a negligible amount that it doesn't warrant telling you to get a coupe. Driving around in a 98 jaguar convertible sounds about as quite as my 98 m3 coupe in terms of road noise. People telling you to get a coupe probably never really spent real time in a convertible to notice the road noise comparatively speaking, or they've just been in some shitty verts. I personally havent been in an m3 vert and dont know of the sound damping properties of the top but I'd find it hard to believe that it's as shitty as everyone makes it out to be.Comment

Dude, WTF are you talking about??? As a person that has owned 4 convertibles during the last 20 years I can say, without reservation, you need to STFU since you clearly have no fcuking idea what you are talking about here.Originally posted by xmetrix

This is why you need to STFU.Originally posted by xmetrixComment

I dont care what number you pull out of ur ass, that was a retarded statement to make, not to mention completely wrong. A vert is noisy BECAUSE it has a soft top, and you, the owner of 15 different ones, should know this. And yet you don't. Interesting. Welcome to the ignore channel.Comment
