Soundproofing the roof

[hb.sagen]

In my opinion, compared to previous cars, the truck is too loud in rain and tunnels. My plan is to add some Amazon basic "dynamat" mats. I have some leftovers from the doors, and some 3m thinsulate.

My question:

Do the Amazon basic mats smell when they get hot? https://www.amazon.com/dp/B07XMF3KK5?ref_=pe_123509780_1038749300_t_fed_asin_title
