Sound insulation of peugeot 308 with your own hands. Does it make sense?

I decided to make noise insulation for my Peugeot. I spent a lot of money and a lot of time, is it worth it? The answer is in this video.

nice video man. i love your videos, very useful when you have the same car.
i installed a little subwoofer in the same car as you and it sounds very well, if you love good bass. i also change my speakers and, as you expect, it vibrates a lot. so i will do the same as you ! thanks a lot to share your work. and if you want some help to install a subwoofer and its electrical stuff, i’m here ! :)

Great job. I have the same car but my problem is a bit different. I have a rattle noise coming from the dashboard on the driver side. I cannot figure out what is wrong with it. It is only audible on rough surfaces around 30-35 km/h.. I saw other people have the same problem but there is no solution to it.
