I don’t have much experience in high-end luxury cars but I have owned a spectrum of brands from European,domestic and Japanese manufacturers.
Honestly I have never been impressed by a factory system. The H/K in our older Mercedes was a joke. We all know Bose is a gimmick. I’ve heard the Fender systems are pretty good but I’ve never had the chance to demo them.
The best I think I’ve heard is the Logic 7 in BMW.
What are some of your favorites?
2016 vw jetta gli with fender system. Stock is very very clean and moderate loud. Good mid bass presence but muddy overall. Tweeters are sharp and beam easily at high volume.
Currently running it with a SI 12, on 650watts. It will easily overplay the front stage
