I have used over 4 boxes of Dynamat bulk packs in my Civic but that is the roof, doors, whole boot area, rear quater panels ( with custom pods of dynamat for speakers) and then the floor under the back seat.
To be honest i dont care about the weight, when your spending the money on a stereo like i have thats the least of my troubles.
I look at it this way i pay BIG money for my stereo so I can listen to it, NOT everyone out side the car & that way i dont get in trouble by the Police/RTA for noise pollution.

the floor and firewall are the biggest areas for road noise to enter. The floor pan is very thin. When i removed my sound deadening from the floor and firewall there was a big increase in road noise.
As for the clips making more rattles etc. Just buy new clips. Can get box sets specifically for honda with all the clips you need etc. 2 or so boxes would be enough for a whole car.
Correct. Firewall, floor and worn seals around the doors and windows let in lots of road noise.
Dynamat Xtreme is the FIRST LAYER! Great againt vibrations and etc. Offers some noise reductions.
DynaLiner is the SECOND LAYER! This has more acoustic padding and offers better noise reduction. COmes in 3mm, 6mm and 13mm Thickness.
Dynapad is another layer that could be used for floors over dynamat extreme.
And NEW product has been made. SuperLite. Lightweight alternative. Full specs are still coming.
There is different products and materials used for different parts of the car. Just one product isn't suitable for everything.
