Sometimes it might feel like your F31’s factory audio sounds like the TV’s built in speakers. Not the top-of-the-range sound as we can imagine, but… there is a way to improve it. With our Alpha One Speaker Upgrade and Premium Audio System, your BMW 3 Series audio will turn out more powerful, richer and clearer than ever. Let alone – suited specifically for you

Thanks to the custom DSP tuning file we add to our amplifier, your sound system will be tailored to your F31 dimensions and your musical taste. Just brief us on what genres you like to put on while driving and how you like to listen to them. We’ll adjust the tune settings for you.

Like the late 80’s funk? Or maybe you're a fan of dub techno and reggae? The BMW F31 subwoofer upgrade will allow you to enjoy detailed and punchy bass notes. You’ll feel it as much as you hear it ;)

Before laying hands on any upgrade, you’ll have to check what sound system your BMW F31 is equipped with. The number of available F31 speakers will differ based on your factory option – whether it’s Base (Stereo), Hi-Fi (S676A) or Harman Kardon (S688A).

As far as the installation goes, it’s almost a no-brainer. All you gotta do is disconnect and remove your stock F31 BMW speakers / amplifier, and add the new ones – they fit like original parts so it’s just a plug & play job. What’s more, the install is fully reversible.
