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.

You don’t decide to go for an audio upgrade replacement on a whim. If you are here, your factory G05 audio must have truly disappointed you. Luckily, our Alpha One Speaker Upgrade and Alpha One Amplifier will make up all of that disappointment to you.

Expect non-distortion highs and bass, detailed mids and most importantly tuning tweaked specifically for your preferences and G05 chassis. Prior to transporting your G05 audio upgrade, we make sure to pre-load it with a custom DSP tuning file based on the genres you play in your X5 and the way you like to listen to them. Doing so already gets us closer to your audio desires.

What’s crucial, before purchasing your upgrade you should check which factory stereo your G05 comes with. The amount of speakers and the presence of an amplifier will vary from Base, through Hi-Fi (S676A), to Harman Kardon (S688A). To see which one of those you have, decode your VIN.

The install shouldn’t burden you either. It is an intuitive plug & play project, easy to handle even by a beginner DIY-er. All you gotta do is disconnect and replace your factory G05 BMW speakers / amplifier, with your new kit. Everything is fully reversible.
