That's one of the things I'm dealing with right now! I personally know Anthony (Ant) from Second Skin Audio (the owner of DIYMA.com, Do It Yourself Mobile Audio), so he was the first one I talked to when I decided to jump into making my car quiet.
What I ended up with was bulk packs of Damplifier Pro (their better version of Dynamat Extreme) and one bulk pack of Luxury Liner Pro (their mass-loaded closed-cell-foam/vinyl barrier).
Damplifier Pro:

Luxury Liner Pro:

For filling quarterpanels I have at least one layer of Damplifier Pro covering the outer quarterpanel, the wheel arch, and the inner quarterpanel, and have cut and folded Luxury Liner Pro to fit in there - to work best, the closed-cell foam barrier should be as complete as possible (no gaps). I haven't finished everything so I can't comment on the difference it makes, but I can say that the "clap test" shows significantly less reflection inside the car.
