Well, it's finally warm enough here in Indiana. First off I'd recommend any one desiring to sound-deaden your car just set aside $250 (bit less) and a whole weekend where your car can be gutted and unused and you don't have anywhere to go.

Tools you'll need with your RAAMaudio supplies (ensolite, raammat bxt, spray adhesive):
Average size screwdrivers, one of each phillips & flat
Socket set, in mm's
2" and 4" socket extensions
8mm, 10mm, 14mm (think 14 is right)
1 pair hearty scissors
1 utility knife
Patience
Short handled rubber headed sledgehammer (5lbs?)

Optional:
Thin, mechanics, or otherwise tactile gloves, washable
Small boombox with CD player & good tunes
Moving blanket
Time to do it 'all at once' instead of in sections

Your moving blanket is going to be folded up in various formats to accomodate your midsection and chest or back as you lean into the car and/or your knees while you do so.

Boombox keeps you moving, working, chipper.
The gloves will prevent your hands from getting the tarry bottom of BXT on your skin, only two methods I have found for removal:
One, use a piece of BXT agains skin and pull quickly away, like waxing. It takes sticky along, though not perfectly.
Two, scrub with dish soap (Dawn I chose) and the scrubby side of a dish sponge under warm to hot water. My hands are tore the f- uP after two evenings spent working.

The time is simple. I started on passenger side floor. You have to take the back bench out to get to the carpet and get it up for bare metal access. I have to pick up a kid every day, and in this state the law says backseat and booster. So I had to put it all back together again first night. Then second night I got the hatch floor and beneath spare, and finished the bench area. Then put it all back together again. Tonight I do the driver's side floor, then put it back together again. Good news is I don't have to take the back seats out again after tonight. Or any seats for that matter. Doors and hatch door are next.





Okay, I will continue forthwith, w/o pictures.

...continued...

Each side of the car is symmetrical; taking a seat out is taking a seat out, the panels in the door jamb, etc, work the same way as well. I will be 'vague' in my description of 'sides' to this effect.

Your front seats are simple. Each corner has a plastic guard on it. Take this off gently lifting up with both hands from the bottom. It should pop off with minimal effort and no breakage. Against the floor itself on each corner of the mounting rail you'll see a big lone bolt. These bolts are going to be the same size as bolts in your hatch holding the seat back for the bench in. They are also the same size as the bolt in the side of each front seat, beneath a plastic cover that pops off with a flathead, holding your seat belt onto the chair. All of these size bolts are going to take some effort to 'pop' the first time. Once you feel it 'pop' the bolts are almost removable by hand; use the socket until a turn in the opposite (righty for tighty) direction doesn't clack any more because it is too loose. Here I just use my thumb and forefinger OR take the extension off the wratchet and twist it manually.

Repeat for each of 4 corners. Now the seatbelt has to be removed, pop the plastic cover off the bottom of the seat closest the door; inside you'll see another of these big bolts. Get it out, and let the seatbelt pull up and hang. Don't worry, you won't lose it, there's a plastic stopper.

The seats lift out fairly easily, they're just a bit cumbersome/large so careful on the paint!

Next examine your kick panels for one of two 'button' fasteners:
One has a smaller button in the center, this pops out simply with your flathead, then pull out the bigger surrounding button. It's kind of like a 2-in-1 drywall stud, the button expands the casing into the hole. The other type of button has a similar/same diameter, but is one piece of black plastic. This you need to wedge the scissors under an edge, then slowly work them under so each prong is beneath the head exerting equal force/pressure, and lift straight up to pull the 'toothed' bottom of the shaft out of the hole. These type generally hold your fabric/carpet down, where as the other kind hold plastic panels.

There is one unique button, in front of the front seats, a screw in the seat of a black plastic sheath. Unscrew it with a phillips head and pull the sheath.

Once the kick panels are removed (the ones on the side nearest the doors will have one 'clip' in the door edge, this pops out nicely if you pull back and up, more back than up, and gently. If you are paying attention you'll 'feel' it's pressure areas and know which way to pull by how the panel resists you.

Now to the door moldings. After the kick panels you can access the long panel in the door bottom/threshold. Pull staight up, trying to work about 25% down on one end first because the clips are not right at the edges, but a little in toward the middle. Again, gentle and straight and you'll have no breaks/issues.

Seatbelt panel is next. it covers the whole column between the front and back seats. It pops off easily, there are no clips, instead it is kind of pressure molded to the rubber insulation strip. Don't worry, it won't take it along, pull out (toward center console area/armrest) from the bottom and the top should come along behind. Last is the small short strip of plastic molding on the back door threshold, same as the front ones, just smaller.

Now all of this is assuming you know how to remove the center console as if you're doing a shifter upgrade, or a shifter bushing upgrade. Shouldn't be too hard to find if you don't know how to do this; check TWM's site or here for these instructions, 'removing center console'.

All that's left now is the bench seat and back. Disassemble the whole rear area/tray and headrests as if you're putting seats down, and do that. Now pull the felt top rear out with the tiny pull at the back, it lifts out like a tray/sheet. Under you'll see two pieces around the spare. Furthest back just comes out, the one behind that has two silver screws in it, one on each side. Take them out with a phillips head. Remove the rear part of the molding, unbolt your spare, pull it out, and remove the 'super emergency' spare beneath it, the foam spacer. Hehe, don't go over 25mph on that spare!

You should immediately see large bolts holding the back seat in, 3 sets of two on brackets, left, middle, right. Pop them out, again these are going to need some real effort to start out. Remember the sledgehammer? Yep, BAM!

Once the bolts are out you can just lift out the seat backs for the backseat. Now where the butt support black fabric ends and the gray starts on each side of the back bench pull up at the front. There is a 'clip' holding it in, just two, one on each side where it pushes and snaps into the metal of the car. At this point you should have nothing but a bare shifter assembly.

WARNING:
DO NOT DO NOT DO NOT remove the shift assembly and attempt to place any material beneath it for sound-deadening. Upon doing this no matter how I reassembled I had trouble putting the car into gear. Any gear. I assume only that there is some kind of 'spacing' issue from the car floor and that it is precise enough that 1/8" or less of RAAMmat BXT and Ensolite is too much 'lift'. I may be wrong, but once I removed the mat and foam I had no problem shifting again. Oops! :)

Pull your carpet up carefully. You can do one side at a time if you wish; I did passenger side one night, back seat bench and hatch area the next, and tonight I'll finish with driver side. Then only doors are left. I haven't done/looked at those yet, so bear with me.

Once you're at bare metal just start laying down mat. I covered the whole area I was doing with mat before I started Ensolite foam. Ensolite went down like butter, and the adhesive that RAAMaudio sells is great compared to the 3M variety of spray-adhesive.

Be certain to cut holes wherever you will cover them. My seat mount holes, the tiny button plug holes, the 'clip' holes where the rear bench clips down. Just pay attention and do an eyeball overlay and make use of your trusty utility knife. You remember cutting out models, don't ya?

So far I've noticed a great difference even if I'm not done. I've read it but had to hear it to believe it. My factory standard stereo sounds like a damn drum and bass demo system. Not /really/ but it sounds amazing. Bass audibility and response alone are crazy; it's better than my '94 TBird with $1000s of dollars spent on the audio. Difference? I never sound-deadened the TBird. Also the highway is almost non-existant now. Yay. I'll finish this when I get onto the doors. Just approach with patience, remember not to lay over wires, every wire I ran across had a mount point which clipped out or somehow or other allowed me to maneuver mat beneath it and foam beneath it so it is still accessible if it has to be, as it was 'standard' before this project.

Well, finished with the floor of the vehicle from the firewall all the way back to the edge of the hatch bottom. Serene interior with no asphalt-rolling noise under acceleration or at speed. Just wind from the doors, and will be doing them over the weekend. Worth the time put in; already sense of car sounding more solid when closing doors or going over bumps/potholes.

Isn't anyone reading? (moon)

:runs around nekkid:
 
Wow that is a lot of deadening. Thanks for the write-up. I want to do this but I don't think I'm up to doing the entire car. I'll probably do the doors and the hatch area for when I finally get a sub that is bigger that 5.25". Glad to hear the stock system sounds much better when properly deadened. Do you have the Bose or no?
 
I don't know if I have the Bose or not, I'm not sure who manufactured the stock stereos in the '07 MS3's. I DO have the bone-stock stereo, coming off my '05 3s I was disappointed to learn the MS3 stereo only has BASS and TREB controls, my 3s had MID as well, which was sweet.

The entire package from RAAMaudio was 77lbs, that's all the Ensolite, the whole roll of Raammat BXT, AND 3 cans of their adhesive spray. I used one whole can of adhesive just doing my floor, maybe 2/3 of the Raammat, and 1/2 to 60% of the Ensolite. I'd say when I finish I'll have added maybe 65lbs to my car? It's fine, from 12/06-12/07 I lost 65lbs, and I'm still going planning on another 65 before 12/08. It will leave me around 245 and I'll still be 'good' about 65lbs ahead of where I was when I got the car April '07. :)

It's SO worth it for the reduction in noise. My buddy rebuilds new Evo's and said I was crazy for doing it, that I should take the carpet and seats and stereo OUT for weight, but I'm not all 'hardcore' this is my daily and I really love putting time and effort into my car to make it unique and better. Can't wait to finish this weekend and have all 5 doors completed.
 
Well if you have a GT you have the Bose, and if you have the Sport you don't. Also it says Bose right on the speaker grills, so sounds like you don't have Bose. However, I was under the impression that only the Bose did not have a MID adjustment and that the base stereo did.
 
Well, nothing says Bose, and I don't have a mid-adjustment, so it's some bastard child maybe?
 
All it takes is inspiration and a shop manual.

Using this post as a template, I embarked on the full "treatment". That's doors and floor. Thanks.

RAMMAT BXT==good. It's 0.35lb per sq. ft. I used 50sq/ft. on the doors. I doubled and tripled in the unsupported areas. I double layered the ensolite. By my calculation I added 23lbs. I'm guessing the floor will be about the same.

I measured the stock road noise at 70-78dB at 75mph on Hwy 101 in California which is a real crappy surface.

I did all four doors and I'm loving it. It makes other cars vanish from your conciousnes. It helped tighen up the Blose audio but it's still a tad muddy. Treating the doors didn't do anything (I could measure) for road noise though.

The floor is next. I'll update with the sound level measurement after I get it done.(deadhorse)

I use these. Also works on wives, installs in 10 seconds, and cost $1.
 
When your doors and floor get done you'll notice a big difference. I like to play, "Window down, window up," on the highway. Hehe. I'm such a 4th grader at heart. :) My hands were F*ED up after my doors. How're yours?
 
Hi,
Great writeup, any pics?

I have only had my MS3 for a few days but the road noise is more than I can deal with, on some road surfaces, I can hardly hear myself think! Its is OK on smooth asphalt, but on concrete or textured asphalt the noise is excessive IMO.

I guess I will need to do this, but dont relish pulling everything out.

For people that have done this, which areas did you find made the most reduction in road noise?

How about tire selection, when it comes time to replace my tires does anyone have any recommendations for a quieter set?

No pics, but I'm getting ready to pull the seats again and layer about two more sheets of the deadening foam down. The floor makes the biggest difference. The doors are a big ol' sonuvabitch, they will cut your hands and arms up, unless you're a leetle guy.
 
I havent done this to the MS3 yet but i did it to my accord. I didnt do the entire floor, just two layers on the floorboard forward of the door, and then two layers inside and out of the door (is in the inside of the outside skin) You have to cut the matt into tiny squares and put it through the holes, and then i covered the holes in the door with plexi glass cut to fit and liquid nail (so i could get in there for maintenance). Sounds like a lot of work, and it is, but the difference between one layer and two is the same as nothing and one. Good write up man. Get some pictures! Time to replace those stock speakers and get the most out of that stuff! Good choice with rammatt too BTW. Ricks the man.

Any news on what gives the biggest reduction in road noise?

Since you have a base line measurement, you would be best to figure out what areas give the best bang for the buck/effort. Apparently the doors aren't it.

What about the doors?

How hard is it to get the doors panels off and is it worth doing the doors as well?
 
Great write up. (first) I wonder if anyone makes a soundproofer which can be applied to/sprayed on the underside of the car/inside of the wheel wells. Taking out seats/door panels worries me about noise/rattles when everything is put back together. Different tires also sounds like a good option if anyone knows of a tire which creates less noise?
