We're the only BMW audio brand like this.

Alpha One was founded by a couple of guys passionate about modifying their BMWs in every possible way with a hefty focus on audio improvements.

Our first big hit revolutionized the game of BMW audio upgrades with the world's first fully customized amplifier upgrade: the Alpha One Amplifier.
While our plug & play amplifier kept gaining momentum, we were working hard to create direct drop in replacement upgrade speakers for late model BMWs, to create a complete BMW sound system upgrade. Thanks to our superior knowledge of everything BMW and an unparalleled level of attention to detail, the Alpha One speaker system came out of the shadows and onto the market.

But! We haven’t said our last word yet — if you’ve been following us for a while you should already know we can’t sit down for too long, so you can expect even more to come.

audio upgrades

When your G31’s sound turns out to be a huge mismatch to your powerful engine, you know it’s the right time to step up the audio game. And be sure, our audio upgrades will deliver.

No matter whether your G30’s audio system is Base, Hi-Fi (S676A) or Harman Kardon (S688A) the Alpha One Speaker Upgrade and Alpha One Amplifier will boost your sound clarity, balance, richness and power. Yet above all, they will bring you sounds adjusted to your musical preferences.

Let us know what tracks you play most often on your radio and how you usually listen to them. Using DSP tuning, we’ll tailor the amplifier to deliver sounds according to your taste and your 5 Series dimensions.

Prior to getting your upgrades, remember that G31 speaker / amplifier options will vary depending on your factory sound system. Decode your VIN to see the suitable audio kit for G31.

Want to take the installation into your own hands? Nothing stands in your way! The process is fully plug & play, reversible and fairly straightforward – all you gotta do is disassemble and remove your current G31 BMW speakers / amplifier, and add the new ones in.
