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
Toyota Supra A90 (J29) original sound system – JBL (S677A) – may already have plenty of power on tap and be quite pleasant, but if you want to turn your car into a true Rolls Royce of sound our Alpha One Speakers will take your audio experience into a whole new level.
Since even the most solid audio materials are not a guarantee of a pristine sound without a premium build, our audio experts made sure to engineer the Toyota Supra speaker upgrades to perfection. Expect rich, well-balanced, natural sound, and most of all a spot-on reproduction of your favourite tracks.
Depending on your stock stereo, you’ll be presented with a different amount of A90 (J29) speakers. So before choosing your new audio upgrade, decode your Toyota Supra VIN and see what stereo is added to your J29.
Because the installation isn’t that intricate, it should be approachable even for a beginner DIY-er. Disconnecting and removing your stock J29 Supra speakers, and inserting the new ones, is simply all you should do. In case you want to go back to your original setup, you are also free to do so.
