Did the soundproofing job during the weekend. 2 packs of cheap chinese sound deadener plus some insulating "carpet" which is usually what manufacturer choose for doors and lining.
Decent overall job...road noise had minimal reduction (tried some before-after decibel measurements with a phone app and it showed -1db on the same road and speed) but the sound of the infotainment is massively improved and the doors have now a premium sounding feel when opening/closing. I would say that now the doors sound and feel more premium than my Q5 and waaay more premium than an A3. There is also a significant improvement of how the car sounds when going over pot holes. It feels more solid and I may have also killed some of the very few rattles I had.
Would I do it again? Probably yes but I would probably go an extra mile with better materials like Dynamat or StP.
