The difference between B Quiet and Dynamat is the price. BQuiet is a quality product that DOES NOT SMELL. That should be the break/ no break point for any deadener you use. I had leftovers in the roll of BQuiet.

I did half the trunk. I did not apply any BQuiet in the rear of the trunk. I used some Thinsulate because it does not weigh anything and I had ample supplies. I applied BQuiet under the carpet and spare tire area followed by thin Thinsulate. I used both together. I did the trunk first and then drove it around and found, like others have said, the sound reduction was not a lot. However, I was very happy the insulation kept the trunk much cooler. After a long drive before the installation, the floor and sides of the trunk became quite warm/hot.

I also applied Thinsulte under the plastic lid shell for the top. I have another thick piece that just lies loose on the top of the shelf. When the top is down is just compresses it. It has a double black scrim so you don't even notice it is there. Works great.

It's very thin foam, I'd guess somewhat universal for headliners, there are different thicknesses out there though. This is the underside of my headliner.


My headliner isn't glued in, it's held by velcro (lots of it) so it is removable.

had some extra studio foam so I tried this to help out w/ exhaust drone...but the drone was overpowering. Seemed to help a little tho.

Can anyone confirm hardtop sound deadening functions or as zero said keeps the sound trapped inside for bad reverberations

Pretty sure I confirmed it in my reply above. My car is quieter with the headliner installed on my Mugen top.

Dynamat in the trunk area alone makes a HUGE difference, it's basically an echo chamber. I did it in the doors as well. Road noise is greatly reduced (well, down to Civic levels) and music comes in much cleaner.

thank you! I might just end up going this route and If I do like the results I might just have to do the carpet aswell.
