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?
I have the upgraded JBL system in my Prius. It is absolutely crazy how much bass it has and it sounds better than any other car I’ve been in (minus my increased road noise, lol)
What year? I can assure gen 2 jbl was pretty mediocre at best
