Good afternoon,
I purchased a 320i G20 2019 with base sound system and i'm looking to upgrade the sound system. I noticed there are 2 underseat woofers and 4 speakers, no tweeters. I'm looking for more bass. I had a look on different posts about sound upgrade, but it's a bit mixed what i found. I give up on Audi after so many years and i'm new in BMW world.
Can somebody advice me?

Thank you !
