Hey guys,

I'm finally doing my system and I've been wondering what to do about sound dampening. I know there are a lot of options out there, but I really don't know all the differences. Can somebody recommend a good product for behind my speakers in my doors? Do you guys use a type of fabric, or is the spray-on stuff better? I just don't want to lose sound behind my speakers. Also, should I get something for the A-Pillars, or do tweeters not need sound dampening to sound better? Thanks.

hey Brian....

They pillars dont require dampning...

Many 5th gen owners will agree, midbass performance in our cars goes way up with well dampened doors, partcularly our front ones. Just about all stick on deadners work well as long as its applied correctly and the adhesive is good. I happened to use Stinger Expert Roadkill-works really good and comes in sheets- so i was able to buy a sheet a time as needed as Don @Unexpected Creation(pearl96max) had it in stock.


Our rear decks (both bose and non-bose rattle a bit if you plan on running subs- my belief is some fatmat or other foam liner between the rear liner and deck will help, as well as dampner under the trunk lid and parts underneath the rear deck.
Now the trunk floor and whatnot is overkill IMO, it doesnt present any rattles or resonance in my experience

You might also want to try Raammat. Good stuff!

@MannyNJ2kmax...

Did you dampen the entire door, or did you just dampen the immediate area around the speakers? I'm planning out my system right now, and want to ensure that my front speakers are installed well and put out the best sound they can. I'm going to go with separates up front this time since I've always had coaxials all the way around in the past.

^^ hey manny, did you remove that clear plastic liner crap that's already there or did you just deaden over it? i have soooo much deadener but haven't been too sure about the approach for our doors

So you have to do the whole door and not just the area behind the speaker itself? I guess this helps lower road/wind noise a little too?

of course u have 2 take off the plastic weather guard. if not it wont work. the mat must be attached to the metal with no bubbles.

truthfully when i deaden my doors i really couldnt tell the difference in road noise, however panels definately dont rattle that much. i did three doors. two front one back. the reason i omitted one was because that door needs repairs. i also did the rear deck.

Yes, you remove it, and you can put it back on if desire to afterwards

really no science to it- just cust pieces and add throughout- basically just solidifies the doors and allow the speakers to work better IB- All loose clips were pulled out dampened underneath so that they would have a cushion underneath them
It really did not solve much of a road noise issue, in contrast to what some tend to believe- 95% of road noise comes from the wheel well area and engine bay to dash area

I think much of the noise comes from the window since your ear is almost next to it.

Road noise is that created from your car while in motion....tire noise and engine noise enter the cabin and negatively affects cabin gain, SQ and some db's......And Armelious-you just contradicted yourself Yes , your window is next to your ear, but you did not add that stuff to your windows, did you? If you have wind noise, i dont see what adding that stuff behind your doorpanels achieves.....

aluminum foil works for me. it's cheap and it works!

i just lined the back of both of my front door panels with 1/2 green foam. its stopped all the rattles and vibration, reduced road noise, makes the doors sound more solid when the close, and only cost me about $30.. the foam applies pressure to EVERYTHING in the door. from the thin inner door skin, to all the rods for the power locks, and keeps everything from vibrating

You wouldn't happen to have pics, would you? I'm assuming that you applied the foam to the back of the removable plastic trim, right? (as opposed to the metal door itself)

best way to eliminate road noise is buy quiet tires

How about some suggestions.
