Whatever audio system is featured in your F26 – whether it’s Base, Hi-Fi (S676A) or Harman Kardon (S688A) – you must always feel like you’re missing out on those spot-on notes and tones.

Our Alpha One Speaker Upgrade and Alpha One Amplifier will bring back the missing puzzle. The sound will become brighter, more accurate, crisp and powerful, but most importantly adjusted specifically to your X4 chassis and musical tastes. Thanks to the custom DSP tuning files we equip our amplifier with before shipping, we can adjust your settings to any music you like to put on while driving and the way you prefer listening to it. Our top priority is to make sure your songs sound great immediately after the upgrade install.

The amount of F26 speakers and the presence of an amplifier in your kit will depend on your original X4 system. So before making a decision, decode your VIN.

If you’re a hands-on DIY-er, this will be a perfect opportunity for a little play :) The installation won’t be a complex project, as everything revolves around disconnecting and removing your factory F26 BMW speakers / amplifier, and replacing them with the new ones. All is fully reversible.
