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

No one decides to replace their car audio on a whim. If you are here, there’s only one explanation – your stock i3 sound system has failed you hard. Luckily, our Alpha One Speaker Upgrade and Alpha One Amplifier are going to make it up to you.

Prepare for smooth highs and lows, crisp, natural mids and most importantly, tuning adjusted specifically for your musical taste and the BMW i3 chassis. Prior to shipping your new i3 amplifier, we always aim to pre-load it with a custom DSP tuning file based on the types of tracks you enjoy listening to and how you like to play them. Covering the above already brings us closer to meeting your audio desires.

What is vital though, before you decide on your upgrade you should check which original stereo option your i3 has. The amount of speakers and the presence of an amp will be different in Base, than in Hi-Fi (S676A), or Harman Kardon (S674A). You can look up which one of these is yours by decoding your VIN.

The install shouldn’t be burdensome either. Beginner DIY-ers will find that project rather intuitive, as all there is to do is disconnect and take out the factory i3 BMW speakers / amplifier, and replace them with a BimmerTech kit. Plus, everything is entirely reversible.
