Dynamat in the trunk
 

Hey everyone! While I'm waiting on my clutch to be shipped, I decided to isolate my trunk from all the road noise and mainly because of the Tomei exhaust I have. So far I've stripped the trunk, which took me around 20-30min because I had to look up where the pins are located at. Anyhow, I will keep updating this thread as I'm making progress.

Dynamat: $150 from Amazon

Next step: Cleaning.

Do they recommend anything,or just soap and water?

Nice! I have been meaning to do this but don't want to spend that much on dynamat - I've heard there are better alternatives.

Just irritated by road noise, luckily the Ark CBE isn't that loud on normal driving :)

Yes. I vacuumed, cleaned with a wet towel, and then rubbing alcohol. The surface has to be clean in order for the dynamat to stick well. You don't have to clean as much as me if your trunk is somewhat clean. I'll recommend rubbing alcohol though.
Here is the result.

Next step: Putting the dynamat(which I've already started). I'll try to finish today after work.

I hear you. But for $150 I'd rather try to isolate as much as I can. I even measured the decibels in my car at idle(low 20s). So I'll compare afterwards and let you know.

If you put a layer of closed cell foam over the dynamat you'll get a much better result. Google "ensolite". It's cheap, light and self-adhesive.

:iagree:

Dynamat is just a vibration dampener. The CCF is the stuff that actually helps with noise.

No need to pay for the Dynamat name. I used GTMat's Onyx product (they are local). It cost <$50 to do the entire hatch.

I'll first do the Dynamat and then if I'm not satisfied with the results I'll try what you suggested. Thanks for the tip! :tiphat:

Honestly, why put the plastics back in to pull them out again? You'll be much happier in the long run if you drop $50 on some foam before you button everything up. It does much so more than the dynamat.

My back would not have given me the option to do this project twice. Leaning over the hatch for hours gets really old.

You are right. I'm not sure if I can post links here but is this the foam you are talking about? http://www.raamaudio.com/ensolite-iu...on-the-market/
I wonder if I can buy it locally instead of waiting to be delivered?

That's the stuff.

Here is the update.

I still have 1 more day worth of work till I finish it completely. I have a question though. Do you guy think I should put dynamat on the middle divider(across the 2 fenders) ? Oh, car sounds quieter even now, I test drove it :)

What about this product? Sound Dampening, Vibration Damping, Thermal Insulation for automotive applications - HUSHMAT.

That's why I just decided to climb into the hatch. Also it was a good avatar photo op :icon17:

I put material on the middle divider.

Wow ... you still have a whole day left? I think I did my entire hatch in about 6 hours minus an hour or two for breaks. I was working from 12" squares though, so I did very little cutting until I was filling in the last areas.

Looks good man, now that extra umph in the back will help u hit the corners on the drift better...
