DIY Sound Deadening Install on the CR-V

Putting The Dynamat in the 'V before I put the panels back in and button it back up!
Give some info on what to do with sound deadening, how to install it, and some tips for understanding how to get the best results.
Just some info:
about 10db of reduction cuts your road noise in half, about 80% coverage of car surface is a sweet spot, more than that has diminishing returns, and I did the CR-V, minus the floor under the carpet (had fuzz left over from stock padding that I couldn't remove) I used about 12 sheets. I used about 1 sheet per door, at least 4 for the trunk, and at least 4 more for the rest of the areas covered.
