Upgrading from the BMW factory speakers to our Alpha One kit will make a huge difference to the quality of the sound in your vehicle. We use premium materials and a carefully honed design for improved clarity and performance, giving a more refined, enjoyable sound. With around 30% greater power handling than the standard OEM speakers, Alpha Ones are also capable of greater volume in appropriate setups.
Owners of vehicles with a basic factory stereo — without tweeters or a separate amplifier — will notice an even greater improvement when adding both components to their system with our Alpha One kit and Premium Audio System.
The Alpha One speakers are a marked step up from any other plug-and-play speaker kit on the market; both our speakers and amplifier are meticulously designed from the ground up for optimal performance in your BMW, for a truly remarkable sound out of the box.
But a lot goes into building a great sound system, and standout speakers like the Alpha Ones are just part of the puzzle. Other companies can offer speakers, but only BimmerTech has the combined decades of experience working with BMW electronics and audio expertise to create equipment that perfectly matches your vehicle's factory stereo.

When buying a Premium Audio System alongside your Alpha One speakers, we are also able to tune the amplifier to match not only your vehicle, but also the speakers you have fitted (Alpha One or OEM). This results in a far better sound than you'd get from a one-size-fits-all solution from another brand.
Yes. We designed the Alpha One speakers to perform in BMWs with a range of stereo systems, including the most basic options without a separate amplifier. The Alpha Ones will still be a noticeable improvement over the factory speakers. To make the most of your new speakers, however, you may want to add our Premium Audio System amplifier.
Yes. Adding Alpha One tweeters to a vehicle that did not come with tweeters from the factory will require replacing a trim piece in the front doors, in which the tweeters will be mounted. After selecting your model, you'll see the list of parts you will need to purchase to install your kit. Contact us for more information.
Almost no mainstream aftermarket speakers have the power handling to take full advantage of the extra wattage provided by a more powerful amplifier. Even our Premium Audio System is tuned at less than its full power output to prevent overloading the speakers. More powerful amplifiers are useful only in custom speaker installations usually requiring dedicated speaker enclosures.
The true benefit of our Premium Audio System isn't just the increased power, but the improvement it can make to the quality of the sound, thanks to the 64-bit DSP and high signal-to-noise ratio. Our expert audiophiles use this capability to tune your amplifier to suit your specific vehicle and speakers, meaning you'll get a more pleasant sound than you would from an amplifier that hasn't been professionally adapted to your vehicle, whatever its specs on paper.

Our amplifier is designed to perform best with the BMW OEM HiFi speakers or our Alpha One kit. With either of these sets, we will tune the amp to bring out the best in your speakers. If you upgrade to the Alpha Ones at a later date, we will provide a tuning file to adjust the amplifier's tuning for your new speakers.
The Premium Audio System can also be used with other aftermarket speakers, but we are not able to provide dedicated tuning files. For optimal performance, we recommend using 2Ω subwoofers.

We have chosen not to publish frequency response graphs for our speakers because we don't believe this information is useful in a car audio scenario. The interior of your vehicle — including its size, shape and materials — is going to have a significant impact on the sound you actually hear, and this won't be shown on a frequency response graph.
We took frequency measurements during the development process, but the sound that really matters is the sound in situ in the car, where we did the bulk of the tuning work when developing our Alpha One kit.

We have published specifications for our speakers on our website in the 'Specification' section to make it easy to understand what each speaker offers.
In terms of other aspects of the speakers' design, we have purposefully chosen specifications that are well suited to use with either a factory BMW amp or our own Premium Audio System. This balance of capabilities is what gives our speakers such an impressive all-round performance.
We do not offer a money-back free trial. If you don't have the opportunity to hear the Alpha One speakers for yourself before buying, you can check out what our happy customers have to say about their phenomenal sound:
