So I have seen a lot of grumblings about how bad road noise is in our cars. I have installed some dynamite equivalent in my car and it is now much quieter than my bmw. 128i. I was genuinely surprised by the improvement. All you will need is 50' of 50mm fatmat, a box knife, a small roller to press it into place a heat gun and some aluminum tape to cover any edges that you feel might need it. Takes about 2 hours and remember it does not need to be perfect because it will be covered by a door panel. All said you can get what you need for about $150. Sorry about the quality of some photos.

The instructions are for the front door but the process is the same for the others except for the small piece of trim by the mirror.

Remove the trim by the front mirror


Remove screws that are under the door handles. There are 2 on each door


Pull door panel till it pops off then unplug the switches and remove door pull from panel.

Cut layers of fatmat to size using a box knife (scissors will get clogged up) to cover entire panel heating the fatmat till it is warm enough to adhere then press it into place using the small roller. If you overlap don't worry, just make sure not to cover any holes the panel snaps into. Cover any edges with aluminum tape.

then cover any edges with your aluminum tape.

As you can see it doesn't have to be a work of art. :) works the same no matter what

It's easier than it looks and made a night and day difference in my car.

Follow steps in reverse when your done and repeat for each panel.

Looks very nice. Thanks for the walkthru! I might do this in the spring.
Thanks. I meant to add this in the walk through. I would try and do it before it get to hot. The sound deadener will stick to anything and stay there once it's warm. The colder temperatures definitely made it easier to place exactly where you want it to go.

You did the 4 doors for 150.00 ? What kind of weight do you think it added to the vehicle ? Thanks..

it might make more sense to get 100sqft and all the tooling on amazon for a few dollars more and do the trunk as well which is what I did. All said it was less than 30 lbs and if you just do the doors it would be less weight than that.

This is something I want to do as well with Damplifier or Raammat and also add a layer of thermozite or overkill.

Dont wait. Probably one of the single best improvements to the car.

2014mazda6, thank you so much for sharing. Most folks on the wind noise thread suspect the noise is passing through the window seals and the pillars. looks like that is not true based on what you did. Roughly what percent nosie reduction did you feel after installing the fatmat?

It probably was about 30%. Which is huge. I still hear some noise through the windows if a truck or car is right next to the driver window, a given since glass is acoustically transparent. Overall noise was greatly reduced. I mostly hear just the engine now which isn't a bad thing. I am trying some different materials in the actual window seals to see if I can further improve the noise coming into the car and haven't had any improvement yet but will keep everyone posted. I took some of the door seals off and inspected them and they are quite beefy. I suspect there is little to be gained there. Excited to see if others have similar results to mine or see other solutions.

Instead of fatmat, use either Dynamat or Raammat or Damplifier Pro from SecondSkin (the best of all three). SecondSkin also has Spectrum, a spray that produces a viscoelastic layer for sound deadening (many use this spray over the aluminium tape or on wheel wells when there's prominent road noise).

Soundproofing. As I mentioned in the lengthy "2014 Wind Noise Driver's Side" thread a month back, this is indeed the no-brainer way to go.

This is true to an extent. As many mentioned in that thread, a lot of the noise being experienced seems to be coming from around the window seals. I did my front doors in RAAMmat and it did help a bit w/ the road noise. Yesterday was a really windy day along the east coast and I drove the car a few hundred highway miles. The wind noise around the windows was borderline embarrassing for a new car....and I'm coming from owning an '07 Mazda 3 for the past 7 years.

I still plan to put a layer of Ensolite on top of the RAAMmat on the front doors, and perhaps over the front wheel wells. But just so people understand that sound deadening as described in the original post in this thread will not fix the wind noise around the windows that many are experiencing. It does, however, reduce a lot of other road noise and I still highly recommend it.

Props to the OP for this solid post!

I regret not doing this to my old 2006 Scion xB. That was a noisy car on the freeway. In comparison, the new 6 is already much more quiet.

Does any have experience with these materials in hot climates? I worry about them melting in the summer and sagging or causing an smell. It frequently gets up past 100F in the summer.

Yes, it works well in the summer. I installed RAAMmat in my Mazda 3 a few years ago and when I sold the car a few weeks ago, I inspected how the sound proofing held up over time. Everything appeared exactly as I had originally installed it, and while we don't have 100 deg weather consistently in PA, we do have it in the mid to high 90s w/ some ridiculous humidity for days at a time. No smell, etc. However, if you take the cheap route by using roof flashing, you will smell a tar-like odor during the hot months as it is made of asphalt. I wouldn't recommend doing this, EVER. :eek:

Nicely done.
If this really did result in a margainal improvement, I'd say you located the weak spot.

I have driven a gen 3 twice, and I didn't really note that much road noise at the time.
I found the gen 3 and my CX-5 to be pretty similar in that regard, in addition to many other similarities.

Now that I have been in my SHO for a couple of weeks, I notice the CX-5 is pretty noisy. Though, the craptastic Yoko Geolanders are what predominantly cause so much noise.

Of course. I did not meant that soundproofing will totally eliminate the road noise, and that includes the door weatherstrip wind noise on quite a few who complain it. But every bit helps, mind you.

Luckily, I have no noise irritation at all on my car. No weatherstrip noise that I would rant about, except the road noise from the Dunlops, of which is quite understandable. The engine DI ruckus (also understandable), I had it quiet down a notch using the slightly thicker M1 0W20 with the help of some Liqui Moly MoS2, of which is widely known to quiet an engine. The car now sounds just like from it's 1st hundred or so miles. Sounds like a different car.

Like I said, every bit helps.

Hey - great stuff!

Three questions:
- does this help with door cover rattle due to speaker bass?
- you mention to cover fatmat edges with aluminium tape. What do you recommend?
- I've read on Amazon reviews that the product stinks real bad and needs aeration? What's your take on that?

Thanks!

-It does not, but you can buy 3m door seal and run it around the seaker area inside the panel to help. also make sure you take everything out of your bottleholders in the door. :)
-3m aluminum tape.
-no smell after 3 days. It doesn't smell great at first but it goes away very quickly.

This is great! A few questions though,

- What did you use to remove the little plastic piece by the mirror in your first photo?
- In your overall picture of the sound deadening in place, the bottom left corner metal is uncovered. Would it be a good idea to cover that for more sound deadening? Or will that not work with the door panel?
- How did you use it in the trunk? Adhere it to the bottom of the rear deck? Did you remove the trunk carpeting?

Thanks for the input!

Thanks

The first price pops right off. And ther are some tabs there that need to be uncover for the door panel.

I removed everything from the trunk and the placed dynamat.
