amplifier upgrades

The stock sound system of your BMW is not meeting your expectations? Our Alpha One BMW amplifier upgrade is a very simple way to improve your in-car audio experience. With its augmented bass processing and a hefty power output of RMS 710W and 1420W MAX, you’ll unlock new bass capabilities in your BMW.

Deeper, more powerful, and fully personalized – your BMW amplifier will come with a customized DSP tuning file, optimized for the interior of your ride and your musical taste. Because we know that the “one size fits all” approach simply doesn’t cut it for car audio. Its versatile 64-bit DSP Processor also allows for a wide range of sound adjustability.

Utilizing the proprietary Class GD Technology, our Alpha One Amplifier for BMW is designed for maximal efficiency and minimal heat generation. It’s also equipped with 8 separate speaker-level output channels and an RCA line out for connecting an additional trunk subwoofer if you need one.

Your stock sound system will largely determine the BMW amplifier upgrade. Depending on whether you have regular audio (Base) or some other option (Hi-Fi, Harman Kardon, etc.) installed, the mounting hardware may differ.

Regardless of your factory audio system, the Alpha One BMW amplifier for your BMW is a fully reversible plug & play upgrade. If you’ve ever put together IKEA furniture or Lego sets, you’ll manage this installation well!


All our [[tag_1]] stereo upgrades are designed with easy installation in mind. Confident DIYers will even be able to install a full set of speakers and our amplifier upgrade themselves, at home, in only a few hours. Learn more about how easy BMW audio system installation can be.

Don't want to tackle the job yourself? We also work closely with a global network of authorized dealers. Find your nearest audio shop.

Upgrading from the [[tag_1]] 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 Alpha One Amplifier.

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 [[tag2_and_mini]], 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 Alpha One Amplifier 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 Alpha One Amplifier 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 Alpha One Amplifier 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 Alpha One Amplifier 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 Alpha One Amplifier 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 grap.

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 [[tag_1]] amp or our own Alpha One Amplifier. This balance of capabilities is what gives our speakers such an impressive all-round performance.

How many speakers you will need depends on factory [[tag_1]] speaker system. But with BimmerTech, you don't need to replace them all at once; you can upgrade as many or as few speakers as you want.

For most vehicles, we offer three prepared BMW speaker replacement kits:

  • Pure Bass: only underseat woofers, for powerful low-end sound.
  • Driver's Choice: replacement speakers for the front of the car.
  • Studio Sound: a complete set of speakers for your whole vehicle.

You can even choose speakers individually, if you aren't looking for a full BMW car stereo upgrade yet.

Yes, we offer a full range of MINI Cooper stereo upgrades, for both the standard sound system and the premium factory options made by Harman Kardon. MINI Cooper owners will enjoy the same ease of installation and impeccable sound BimmerTech is known for in the BMW world.
