I have one or two rattles right out of the box that I can point out, but it's all stereo related and to be expected. Add a pretty powerful stereo to any car and door panel rattles like I have are just there. This is with the Sony 10 speaker system, and only seems to be the passenger rear door at certain frequencies.
I'll probably dynamat the doors and panels sometime in the future, but for now, I just turn up the radio or endure for the offending track. It seems to be a very limited frequency range issue.
