I installed the Bimmertech Amp today with their preloaded tuning file. What a difference even with the OEM speakers. 100% confident my 2022 sounds with the upgraded Amp and OEM speakers sounds better than my 2017 X5 with HK.
Took all but 30 minutes to install with 25 minutes of that time spent on one mounting bracket screw.
Debating on if I should replace the front and rear door speakers with focals but honestly not sure if I would hear a difference. I will definitely not replace the subs. They are more than adequate with the additional power.
