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.

If you’re here, you know that your E90’s factory sound system just isn’t gonna cut it for the long run. Even though at the moment it might be acceptable, with our audio upgrades your 3 Series sound is going to get incomparably better. And by better, we mean more powerful, punchier, richer, more accurate and… customized to your musical taste.
Using DSP tuning, our amplifier arrives at your doorstep suited to your E90’s dimensions and your musical preferences. Before we ship it to you, tell us what music you usually put on while driving and whether you like to crank it all the way up or not. We’ll adjust the audio to make it sound ‘yours’ right off the bat.
When it comes to available BMW E90 audio upgrades, the amount of speakers or whether you’ll get to add an amplifier or not will differ depending on your factory system. For E90 they are: Base (Stereo), Hi-Fi (S676A), Top Hi-Fi(S677A), Harman Kardon (S688A) or Individual Audio System (S752A). To be sure which one you’re equipped with, decode your VIN.
The installation should be a mild project even for beginner DIY-ers. It’s a plug & play process of disconnecting and removing your original E90 BMW speakers / amplifier, and putting the new ones in. Plus, it’s all fully reversible.
