well i finally ordered my deadener, should be here in a few days. also i now have a nice digital camera, so plenty of pics coming

what i ordered was one roll of raammat bxt, which is i think 62.5 sq ft, i still have 30 sq feet of edead v.3 the guy threw in with my amp because of some complications. also got 84 sq ft of ensolite deadening foam, to thoroughly do the hatch area and kicks.

im still trying to decide on how to go about sealing up my kicks, anyone have any thoughts or ideas i might try?

 

I wouldn't bother trying to seal your kicks because unless it's 100% air tight (a hard feet to pull off) it's really not going to matter much.

Raammat is good stuff. I have almost a full role on my roof alone I can say right now that you're going to need more deadening be it mat or something else.

When you say Edead v3 you mean the liquid stuff, right? You might be thinking of another product if you're mentioning it in terms of square feet.

I have a few suggestions. First, I hate to ***** ED like this but they just released Edead v4. It's a foam type mat that's designed to go under carpet, behind plastic, etc to kill off road noise. It doesn't absorb moisture, does a much better job eliminating sound than the OEM deadener, and also weighs a LOT less than the OEM crap.

As for actually deadening a car, I think that liquid deadener is the way to go. It's the easiest to install by far. I have a good afternoon and a half of work into my roof for the application of the Raammat that’s up there. The roof is a fairly flat surface that’s not very hard to cover or work with. The floor, hatch, etc are all a good deal harder (not flat, weird angles, etc). Painting deadener on (or spraying it on if you have accessing to a compressor/gun) is a LOT easier/faster and the same results.

Finally: expanding foam. You know that crap you can buy at home depot to fill cracks/insulate pipes/whatever? Comes with the funny screw on straw thing? Buy a couple of cans of the stuff and fill all the hollow spots that you can’t get to with deadener (inside the a pillar, in the sails, in the kick area, behind some of the sheet metal in the hatch, etc. This will cut down a lot of resonance and will make things a good deal quieter.

My deadening plan is as follows: expanding foam, liquid on the floors/doors/hatch, and finally foam mat on top. Odds are that I will be able to get these things done in less time than it would take me to lay the roll of Raammat that I have sitting behind me.

 

how did you use 60 square feet of mat on what, 5-7 sq ft of roof? i was planning on using expanding foam, but i thought raammat was very pliable and easy to apply in tight spots? i thought it was edead v3 i have, but must not be, because its a mat.

im not really planning on doing every little bit of the car, specifically not the firewall. i dont want to pull my entire dash out. planning on just taking out the seats, pulling all the carpet and doing the whole floor and hatch area first, then when i work up the motivation again, doing the doors, roof, and sail panels.

 

Most any mat is pretty easy to apply as long as the mat is stretched uniformly or without much deviation (ie the center can easily go up a 1/2" or so while the edges stay down. It does have an aluminumish backing that limits strechability somewhat. I am going to go liquid to avoid the tight spots (places the mat will easily fit but your hand won’t), corners (the corners of the well for example), and especially for the faster install that I mentioned earlier.

The roof is nowhere close to 5-7 square feet. 5 square feet is a 2.5' by 2.5' square If I had to sit here and guess I would say that the roof is at least 4x5 but it’s probably larger. I am running double thickness and did have a little left over (probably 15 feet) but there’s still a lot of mat up there.

Your plan is fairly close to mine. I have a huge list of interior things to get knocked off and I'm going to do them in one big marathon type event. Weld in cage, deaden (everything but the firewall since most of the interior and trim out will be out at this point), install carpet, install new front seats (ditching power and going to a 'racing' seat), install 5 point belts. All said and done my interior will be pretty much 100% black and it should be fairly quiet.

 

isnt that what rubberized undercoating is.

 

It's probably fairly close but it's my understanding that v3 dries harder and is less rubber like. I haven't used the stuff personally yet so I can't comment for sure. I know that I would be wary of putting undercoating in my cabin but a member here did it to her doors years ago with good results.

 

finally got started this weekend, thought i'd put up a few pics.







kind of tough to tell, but this is the underside of the hatch at the back, where the latch is.






i'm doing basically what gummie did, putting spray adhesive top and bottom of this mdf sheet on the decklid, carpet over it. going to have the power wires on the outsides, coming in from behind the panels on each side, with the rcas, and speaker wires coming out of the carpet in between the amps. just test fitting here, going to put it all back together next week and start deadening the front of the car.

also if anyones interested in the box i built, there are 4 pictures of it in this post.

anyone have any bright ideas where i could put my distribution block and fuse block to keep them out of sight? i'd rather not have to remove panels to change a fuse, but i've never blown one yet so i may just put it behind a panel.

 

Does anyone have like the square footage of all the different areas of the car or at least a rounded off number. Like the roof without T-tops is 10 Sq.ft...the Flr from Firewall to the gas tank hump is 20sq.ft.. and so on and so forth?

 

How's the progress coming on this project? Any signifigant difference over how it sounded previously? Was it worth the money spent, and if not, what product would you suggest instead of Rammat?

Thanks!

 

ah, i had forgotten about this thread. i'm running a bit late for work so i can't host the pics right now, but i've got a few new ones on my computer. i only used about 2/3s of it, did the entire rear hatch, as much of the insides of the body panels as i could reach, double layers on both wheelwheels, most of the metal behind the sail panels, and made a couple of mdf plates to seal up the holes where the 6x9 mounts were. got the decklid, and the area behind the rear seats.

the car is still fairly loud, but its definitely muffled from the rear, the exhaust note from the back is a lot more subdued. you can tell most of the sound is coming from the front and underneath. the bass response is slightly louder, i expected a lot more. but the clarity, and overall quality of the bass has improved tenfold. i can't wait for my next 3 day weekend to do the front of the floor and kick panel areas. going to have to order another roll to do the middle of the floor, roof and firewall. i did just the deadener without the sound absorbant foam mat, and it was a good deal louder than it was after i put the mat on top of it. i dont know what the stereo would have sounded like with it like that, still had it out, but i doubt it would have been very good.

it was money well-spent. more of a factor than the price is actual labor that has to go into it, its a real PITA to do. but if you're dedicated, and want those results without paying someone hundreds of dollars to do it for you, the learning curve isn't steep at all.

i have a 30 ft roll of edead v1, and its garbage. about half the thickness of the raammat and doesnt stick for crap. i tried to use a couple ft on my kicks and took it back out. i'll probably sell that to some local person that doesn't know any better and will likely never install it anyway to buy some more raammat.

 

EDIT: Nevermind, I just went back and read your first post and now I know what you're talking about.
