Hi All
I just bought a 2021 G20 320i with iDrive7. I read that the audio system in my car (standard with only 6 speakers) has a RAM (receiver audio module) build-in.
I would like to improve the overall SQ and loudness and after asking a few well known installers around my area, there are 2 options recommended:

1. Change the 2 front (with tweeters) and 2 rear door speakers to B&W speakers (original OEM).
2. Add a DSP (example an Audison 4-CH amp with DSP) without upgrading the stock speakers.

I don't mind upgrading in stages in the near future but I need to stick to a specific budget now.. :-(

Which option do you think will produce better results?

Thanks!
