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.

Sound system upgrades aren’t something you decide to get on a whim. So if you are here, you must be truly disappointed with your factory G02 audio. Our Alpha One Speaker Upgrade and Alpha One Amplifier will make it up to you.

Expect rich highs, detailed punchy bass, accurate mids and most importantly tuning tailored specifically for your musical tastes and G02 dimensions. Prior to sending out your G02 audio kit, we always pre-load it with customized DSP tuning files based on the music you play in your X3 and the way you prefer listening to your tracks. Covering that base already brings us closer to your desires.

Before adding your upgrade to cart it’ll be crucial for you to check which stock stereo your G02 has. The quantity of speakers and an amplifier will vary from Base, through Hi-Fi (S676A), to Harman Kardon (S688A). To make sure which one is yours, decode your VIN.

The install should not be burdensome either. It is an approachable project even for a beginner DIY-er. All you have to do is disconnect and replace your factory G02 BMW speakers / amplifier, with your upgrade. Everything’s fully reversible.
