Ok, I realize that there are a few things that can cause a driver to lose SPL ratings..Here's a few things that I was curious about..Be patient with me,Im still trying to figure some of this out as I realize that most questions need a definite combination of enclosure/amp/driver/vehicle, other than a bunch of variables...I guess what Im looking for Is some general answers : )
Ok - *Panel flexing - can this be stopped/helped to any degree, or should i just count this one as a definite NO??
*Air leaks - Other than the obvious holes in the fire wall/ subframe, Is there any other places that I could look?? I thought about pating the obvious ones with a silicone based caulking..Good Idea, Bad Idea, Not worth the time??
*Dynomats - worth it or not??

Panel flexing can be minimized by the use of sound dampening materials like Dynamat, Be Quiet, E-dead,Brown Bread and other similar materials. These are very labor intensive to install and not cheap to buy either. A few e-bay sellers offer pretty good deals but when buying a lot, this stuff is heavy and shipping costs need to be considered.

Small air leaks are hard to find, but most can be resolved using silicone based RTV type adhesives on smaller leaks. (Window trim, fire wall, and the like)
For large area dampening, spray on deadeners are often the best option as they cover well, have very good adhesion and one can use several layers as needed. Some products like E-dead matting and paint on liquids are very helpful if you wish to go to that extent.

The sheet goods are great for leaky door panels and dampening doors. The paint on products work well for flooring and interior side panels and trunks.
Just try a global Google search and you will find many ideas from vendors and other forums on such things. "Sound dampening materials". Here's a good how to read:
