Yes. Is like a better sound. I had replace speakers and maybe added a crossover to a prior car (non BMW) and it improved modestly. I've fine tunes the EQ on the bimmer, and while its "ok" it's certainly not premium. At least compared to others on the market. I am not trying to make it into a B&O system although that would be great, but just spend maybe 700-1000 on some speaker upgrades and maybe an amp to add. I don't want the big subwoofers or anything like that. Nothing custom, no panels, etc.
I can go locally to a car audio shop but thought others may have ventured into this and offer some recommendations.
The sound is not as robust or impressive as I'd like or expect.
