Dynamat in the trunk

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.

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

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

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.

You have a local contact? Send me a PM, I might pay them a visit or just an email - trying to get an idea of how much they charge? I might just do it myself on a saturday, though.

This. It's really tedious, but not hard. I can imagine the labor on this being really high.

It took me 3 days x 2 hours every day after work. Now, the labor is simple enough, however it's tiring. You are either bending over the trunk or cutting the dynamat inside the trunk (unless you want to get out of it every time you need to cut something).

Spent about 4 hours yesterday on my hatch and have it finished up with the RAAMmat BXT II sheets from RAAMaudio. The application was pretty lengthy and tedious like others have said but I this stuff is really flexible and applied very well. Applying the Ensolite foam over it tonight before putting the plastics back in.

The "Package #1" that I bought was the best deal I found and had to pull the trigger last week. It came with 20 sheets of BXT II material (37.5 sq ft) and 3 yards of Ensolite foam (41.625 sq ft). Thanks again, Chuck, for recommending this product.

Excuse the microfiber towel and windex in the hatch

How much sq ft do you want of which product? In addition to the Onyx butyl product I used, they also have a product called Quadro, which is essentially the Onyx butyl product with foam already adhered to it. Pretty convenient, but I have zero experience with it.

And btw, I did the install myself. So that price was just for the Onyx product I purchased, not any labor. I did my hatch install in approximately 6 hours with four 30 min breaks.

No idea how much sq ft I need but I want to cover the rear fenders and trunk - that quadro stuff sounds like it has both the deadening and vibration material.

My other question is if we need to entirely cover everything? The CLD Tiles site mentioned just putting it in patchy spots as you don't need to cover everything - is that the same for this stuff?

I think to cover the whole hatch it takes around 30 sq ft of material.

You don't need to cover everything, I haven't. The more you cover the better the isolation.

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!

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?

Chuck, I think you just sold me on a kit from RAAMaudio. I'm thinking about purchasing the "Package 1" kit today that includes 37.5 sq. ft. of their BXT II sheets and 41 sq. ft. of their Ensolite.

That's what I used. It's not a bad deal at all.
