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

If you’re here, you know that the time of your E92’s factory sound system is over soon. Even though for the time being it’s hanging in there, with our audio upgrades your 3 Series sound will be incomparably better. And by that we mean more powerful, punchier, cleaner, more accurate and… suited to your musical taste.

Using DSP tuning, our amplifier shows up at your door adjusted to your E92’s dimensions, speaker location and your musical preferences. The only thing you have to do is specify what music you like to put on when hitting the road and whether you play it at moderate levels or not. We’re going to tailor the audio settings to make it sound ‘yours’ straight after the install.

Speaking of the available BMW E92 audio upgrades, the number of speakers or whether it’ll be possible to add an amplifier will depend on your stock system. For E92 they are: Base (Stereo), Hi-Fi (S676A), Top Hi-Fi(S677A), Harman Kardon (S688A) or Individual Audio System (S752A). To see which option you’re fitted with, decode your VIN.

The install is manageable even for beginner DIY-ers. Nothing more complicated than disassembling and removing your factory E92 BMW speakers / amplifier, and placing the new ones in. All is plug & play and fully reversible.
