Wow, big difference. Just traced the carpet on the dynapad and cut it to fit, one piece, about 10 lbs. The quality of ride and sound is tons better and can now hear the exhaust and not the drone.

You mean you put the dynapad under the carpet in the hatch area? I"m thinking about doing the same thing but wasn't sure if you meant the hatch area or some other area?

Thanks

Anyone tried putting dynamat on the underside of the corrugated plastic cover (along with doing the actual hatch). Wonder if that would help as well?

Sarcasm coming.......

That corrugated plastic has a name, it's called coroplast.

Sorry, I had to be a smart arse.

It's not very often I can use terms I work with on a car forum.

Coroplast - Manufacturer of Corrugated Plastic Sheets

I'm not sure you idea would help or not. It was my understanding that it's the actual bonding with the metal of the car that creates the sound absorption. But on this one I could be totally wrong.

Yes, under the carpet, on top of the coreplast. Very happy with the result. Wish I would have tried this before dynamat, might have been enough for me.
However, the combination of both has transformed my ride from what it was.

Yea, something thicker than dynomat. I saw dynomat, very thin. Im thinking 1/2 inch thick insulation under the carpet in the hatch area. Overall, road noise never was much an issue cause its a sports car anyway. But im lookin at larger tires and it may be more of a concern. Im going to Lowes to check out some insulating products.

This idea seems a fast and simple way to at least take a small but effective stab at some of the road noise. Of course further dynamat'ing etc would be more effective.. but if simply finding something thin and foamy to place under the hatch area carpet...makes a difference, I'm in. Please let us know your results!
