Two additional notions emerge at this point. One - this is intelligent, sage advice thus, Dave must have overheard it from someone else.

Two, it is possible that our 180 had this same rattle but was unable to resolve it in time.
Seriously, if you did the upgrade, pull the little panel out near the speaker and look at the "assembly" from that perspective. If you bought your car used, pull the little panel out near the speaker and look at the "assembly" from that perspective. Onehundred80 would not have offered this guidance unless it was potentially a problem.
I have no other ideas but this may be plausible.
I do appreciate the response, but the car was bought in '05 and barely used, I don't think the previous owner (chrysler exec) did the mod. in fact, I know he didn't! I took apart the doors a while ago and put dynamat in them...
