MX5 sound insulation

Servus, I want to keep my Miata a little bit better so that the driving noises don’t get through. I’ve been a little smart and I’ve set up the following battle plan: Dress the entire floor with bitumen mats. The doors with alubutyl are insulating, a little insulating tiles towards the interior, after the steam barrier. The trunk is also paved with bitumen mats, just like the wheel boxes. Do you think that’s meaningful, or would you do it differently? r should also a better music system pure, is this also a good basis for it? Many greetings, and thanks already in advance.
