At times you may get a distinct impression that your F34’s factory audio sounds just like the TV’s built in speakers. Not the highest quality sound as we can imagine, but… leaves a space for improvement. With our Alpha One Speaker Upgrade and Premium Audio System, your BMW 3 Series audio will get more powerful, richer and clearer than ever. Let alone – tailored just for you.

Because of the custom DSP tuning file we enrich our amplifier with, your audio will be adjusted to your F34 dimensions and your musical taste. Share with us what genres you like to play while driving and how do you usually listen to your music. We’ll adjust the tune settings for you right before shipment.

Listening to the late 80’s funk? Or perhaps to dub techno and reggae? With the BMW F34 subwoofer upgrade you’ll enjoy very detailed and punchy bass notes. Prepare to feel it as much as you hear it ;)

Before deciding on your upgrade, you’ll have to know what audio system your BMW F34 is fitted with. The amount of available F34 speakers will vary based on your stock option – whether it’s Base (Stereo), Hi-Fi (S676A) or Harman Kardon (S688A).

The installation is almost a no-brainer. All you should do is disconnect and take out your stock F34 BMW speakers / amplifier, and put the new ones in – luckily they fit like factory parts so everything revolves around a simple plug & play job. Furthermore, the install is fully reversible.
