Seeing that you did almost every essential places with dynamat execpt wheel arcs? But good job on those. How much it improves soundproofing because on my 2004 avensis I have same job ahead of me. In my vehicle it's almost impossible to sit in the back if you have to sit there for 2+ hours because tire noise and outside noise breaks your mental health. So my question is how much dynamat improves soundproofing specially backseat perspective?

When you sound proof your car remember that your doors get condensation and rain water inside. Adding extra insulation material everywhere may increase moisture, reduce drainage and cause premature rust issues. This can apply to all body parts but especially to outer ones like doors bonnet, boot etc.

by chance is that under the hood not a fire risk by chance plus i got that sound proof stuff for my new speaker upgrade that stuff i got for my Speakers was expensive enough stuff
