I just did full dynamat and carpet, get a roll of jute from home depot for 20 bucks and fill all the low spots in the floor pan, some places you have build up almost 2 full inches. its probably 3 inches under the seats.
I did several layers in many places and its still probably not thick enough.
Under the seats is like (below) just to bring it back to where the factory spray foam level was.
