Whatever the audio system in your F25 – whether it’s Base, Hi-Fi (S676A) or Harman Kardon (S688A) – you get a feeling of missing out on those ideal notes and tones your speakers don’t deliver. As you well know, a superb sound system is not all about power. It’s about transmitting the music just spot on.

Our Alpha One Speaker Upgrade and Premium Audio System lead the way in both of those cases – they bring that bright, accurate, crisp and powerful sound, as well as tuning adjusted specifically to your F25 size and musical tastes. Thanks to the custom DSP tuning files added to the amplifier before shipping, we can adjust your settings to whatever music you like to play and the way you listen to it. Our top priority is to make sure your songs sound great right from the start.

The quantity of F25 speakers and the presence of an amplifier in your upgrade will be dependent primarily on your stock X3 system. That’s why before making your call, decode your VIN.

Like to be hands-on? Perfect! The installation of our audio upgrade is DIY friendly, as everything revolves around disconnecting and removing your current F25 BMW speakers / amplifier, and exchanging them for the new ones. No big deal, especially that all is fully reversible.
