That is exactly what I am saying. Those two products (foam and dynomat) are designed for absolutely different purposes. Dynomat prevent panel flexing by adding extra weight to it but does very little (comparing to foam) for reducing outside noise. Sound deadening and sound insulation are completely different and work best when combined. The best alternative that had been found so far is laying down some close cell foam, laying strips of RAAMmat under it and on top of it (top layer should be worked with heatgun to almost melting point to stick well to foam). This way you still have lighter car and practically no outside noise.

On any car the biggest source of road noise are doors. Put foam in between the metal door and the inside panel. Also put a layer or two to completely cover your wheel wells, and basically anywhere under the carpet. On my car it worked especially well behind and under the rear seat. Using spray glue adhesive would improve results.
To stick any foam to RAAMmat you need the 3m spray glue but of the certain number. I will find out and post which glue works best. Surprisingly the high-temp (90?) 3m glue does not hold at all.
I am pretty sure you know this Threxx, but for general info here is how to use the spray-glues. Spray both parts that you are going to glue together and wait until the glue is almost dry. Then put two pieces together and they will stick hard. Things are guaranteed to fall appart if you don't let the glue dry and slap it on while wet.

nah, trunk is fine. You might want to do rear deck if you can fit the foam there. That should eliminate any noise from the trunk. Much easier then insulating the whole trunk area anyway.
