Has anyone here done any sound deadening to their xD? I'm thinking about doing this, but I have no experience working with the inside of cars. Do you think this would be a decent project (not counting the crazy amount of time it takes) for a newbie to undertake?

Also, how hard is it to remove everything from the car to do this?

I'd LOVE to put sound deadening crap in my car :) At Scion United there was an xD that had Dyna-mat (?) put in on the doors, roof and hatch I think. They didn't put any in the back C pillar though. When you knocked on the panels it was so solid it was awesome :)

Not sure how much the material costs and how much you'd need, but I'd like to find someone to install or help me install it in my car. Preferably someone who's installed it before :)

There are a few different products out there. E-dead is another one, comes in a paint on form also, I think that would be easier than the rolls of stuff, heard nasty stories of bloodies fingers and such, lol. I've never done either one, but its worth checking into, here is their website...

Looks like I'm going to probably be going the Lizard Skin (www.lizardskin.com) route.

Of course one of the problems I've noticed with most of these products, is that there aren't really any good reviews on them. No before/after dB measurements, etc. Whenever I end up doing this (probably next month, though it might be sooner) I'll post pictures and take some crappy dB measurements of road noise using a radio shack spl meter. (There's a really noisy road near where I live that would be good for this.. my ears hurt after driving on it)

Speaking of this in the xD.. has anyone taken completely apart the xD? Wondering how difficult this will be. Maybe I'll go for a trial run of taking some of it apart and putting it back together.

Check out raamaudio. Raammat is good stuff and won't cut your hands at all. they sell ensolite foam padding as well that sticks on top. Looks great and sounds even better.

Well tomorrow I'm going to a paint+body shop and I'll ask and see if they have experience with this sorta stuff. Then get an estimate ;)

it is really cheap there and shipping is pretty fast if you live far away from their warehouse. ^ChelsDS, i've done this before, it just takes time to do it right and it's best to put when it's hot so it can stick on right. for an xD if you want to damp the entire car you would about 4-5 bulks from top to bottom including the doors. haven't done it yet for my tC but it's gonna run me about 3 bulks due to the glass roof..YES!

I've done some dynamat work before and it is pretty tedious. You have to take EVERYTHING out down to the metal pretty much. On top of that, the edges are sharp!!

On the flipside it makes a HUGE difference in road noise, especially if you know where to put it. I imagine in the xD a lot of the road noise comes from wheel wells and the rear doors (they feel like toy doors to me) plus the hatch.

Be careful if you deaden the hatch, though. I know in the tC if you put much material there it actually adds so much weight that the hatch wouldn't stay open!

Even thouugh it's for an xB there is a thread here somewhere where somebody completely stripped and xB and added sound deadening-might help you in some ways.

yes if you put alot on the hatch for the tc and have a spoiler it will not hold open but for the xD it's different so it should hold and be alright with 1 sheet from the inside and filling up the plate as well which is the worst of the rattling noise as you all know.

dynomat takes a loooong time, done right. I can't imagine a shop wanting to do this....plus, a shop isn't going to do rap tests, double up, get into every nook and cranny. If you want something done right, do it yourself. Check it.

i've seen some shops actually do it but for a large cost and they even do behind the dashboard, talk about a mission right there. :relief:

Has anyone compared the liquid/paint vs the dynomat-type insulation? the liquid sounds a lot easier to me and won't take a few weekends to complete.

the liquid is actually pretty good as well when it stiffens up, it is called "Bruttle Tape" for it which is the exact same black sticky stuff that dynamat uses under that aluminum sheet. it is mainly used for like sealing automotive and home windows when there is gaps and leaks. any window shop can sell you this but it comes out abit more unless you can get it from a warehouse for wholesale pricing.

Wow, even take the wires off too? I wouldn't be comfortable at all doing it myself.. lol. :doh:

no it goes over some wires and others over the sheets.

Heard this stuff works great, I may try it out.

Holy damn that's cheap! I imagine it's about the same as Dynamat from the looks of it. Worth a peek at the local Lowe's that's for sure.

yeah that's cheap but it's more for roofing and not windows to elimate outside noise.

From what I read peel & seal works if the inside of your car doesn't get too hot. If your car gets too hot, the asphalt inside melts and goos up your car.

Oh yum!

hmmm, never thought about that, would make a diff. but it does get hot around here once or twice a year.
