Dynamat is great stuff - I highly recommend it.
However - the resonance you hear is probably not really resonance - it's more likely just the sound quality coming from those factory speakers.
I've swapped all of my speakers out and changed the head unit too. What a difference even without the dynamat.
I'm sending my E in for 2 amps and a few other goodies that will require most of the panels to come out of the car - as I've always done in my past systems, I'll have the installer put Dynamat just about everywhere during this process.
I'll update you with real world numbers after it's complete - my installer has a tool for measuring ambient sound. We will use this before and after installation to get a difference in ambient sound level (road noise).
