Default Dynamat question

For those who have put dynamat on your floors, did you put the original underlayment back on top of it or just install the carpet on the dynamat?

Can't see where putting the underlayment back in would hurt anything but figured I ask.

I did since I already had it. I don't think it makes much of a difference either way.

IMO Dynamat is mainly for sound reduction, the underlayment is more for temp/heat insulation. JMO.

You can google and learn that the dynamat is to stop resonances and not sound transmission through the metal, the stock stuff will help tremendously.

Do all the stock stuff, and the Dynamat/FatMat.

There's sound deadener, and then there's insulation. You need both. And make sure you get the "jute" style insulation. It makes the carpet fit better, too!

I discovered today that I hate putting dynamat in even more than I hate putting headliners in! That tranny tunnel was a BEAR! Spent 4-5 hours on my knees in the garage and got about 1/3 of the floors finished along with one cowl side panel.

I got the Dynamat Ultralite. It's actually not THAT bad but all the compound curves on the floors makes it time consuming to install. The inside of my car looks like a giant Klondike bar!

I figured I'd put the old stuff back in since I have it and it's in good shape. Thanks for the replies!

It took me the better part of a full day to install dynamat throughout the interior and roof. Although I have not done so yet, the plan is to use the carpet underlay in conjunction with the dynamat. With the dynamat alone I can already hear a huge sound reduction when the motor is running, and the roof seems more solid as well. Good Luck!

I dynomatted the areas outside the oem underlayment. Saw no noticeable benefit to doubling up.
