Get Crystal Clear Sound. Just by replacing your BMW's speakers.

We took your factory BMW speakers and re-engineered and improved every aspect of their design for one thing: great sound. So you can simply swap your original speakers for ours without changing anything else in your audio system, and the results are astounding.

All inclusive... everything you need for a total transformation.

Replaces every speaker in your BMW (except subs), and includes absolutely everything you need except basic tools (which you won't need if you have one of our authorized dealers complete the installation).

You get great sound with just the Stage One because it was designed from the ground up to maximize the performance of the rest of your audio system - all by itself.

So there's no need to buy anything else (such as amps, wiring, or a new head unit).

Play your music louder. And enjoy every note.

The speakers in our Stage One Speaker Upgrade produce higher quality sound and a wider range and more balanced reproduction of the bass and treble you're currently missing. That's because, unlike your factory BMW speakers, we use proven audio technology: woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters.

These technologies, working together, result in speakers that remain distortion free at higher volumes for accurate, natural, beautiful sound at volumes much louder than your factory speakers.

(For more bass response, we recommend a BAVSOUND subwoofer system.)

100% plug & play installation. Simply remove your old speakers, and plug in the new ones.

Everything about our speakers is 100% custom, and 100% matched to your exact BMW, right down to your specific audio system, body style, and amplifier -- which is why they just might be a better fit than the originals.

Easily install it yourself. Or visit a Bavsound dealer, and leave it to the pros.

Every Stage One includes step-by-step instructions, and is designed to be easy enough that anyone can install it in just a few hours. An afternoon and basic tools is all you'll need.

But if you're not a do-it-yourselfer, just leave it to the pros and have one of our Authorized Bavsound Dealers install your Stage One for you.

4 year warranty.
Our products are bulletproof. So is our warranty.

Everything we sell has been engineered for durability and longevity, and we know what we sell will last. And last. And last. That’s why our speaker upgrades and subwoofer systems are backed with our industry leading 4 year limited warranty. So if something breaks, send it back. We’ll replace it at no charge.

Outstanding

Amazon's stock went up $5 due to my desire to relive music that I haven't heard but still loved in over 30 years.

Great clarity, no distortion, and marvelous accurate reproduction of many genres of music. Tower of Power CDs never sounded so good without high-end headphones. Great upgrade for my 2015 3 series BMW.

Ruby Red e46M3 & Bavsound 1 Brings the Clarity of Sound to 11 Year Old Harmon Kardon System

Having upgraded my 2015 BMW M4 with Bavsound 1, when I bought my 11year old low mileage e46 M3 it needed the sound system to be brought back to life.

I contacted the guys at Bavsound and asked what can you do to my bring clarity back to my Hardon Kardon System which sounded flat and lifeless. They told me about the Bavsound 1 top Hi Fi upgrade for the e46, so that was it I placed an order and then waited for it to arrive.
Having already had a Bavsound1 fitted previously I know how it is really a plug and play installation and the supporting you tube videos and technical support from Bavsound support makes the install really straightforward.
Once installed capacity I had hoped that my 11 year old Harmon Kardon system would offer greater clarity and it does. It is clear at the higher ends and also the vocals are much clearer too. My only wish is that Bavsound offered a Subwoofer replacement for the e46 not that I really need it right now but who knows what the future will bring. Very happy with the upgrade and recommend it very highly to anyone looking to get better sound clarity. Denso

Excellent Sound Quality

It's amazing how far the sound quality can decline without becoming obvious, like a frog in water slowly brought to a boil won't jump out of the pot

the owner may not notice since ithe degradation has been spread across years. What a happy surprise when excellent sound suddenly happens in the same car on the same day with a simple speaker swap. Once I understood how to remove the rear speakers (four hex head screws accessed from topside) the install was easy. I'm now back in love with the otherwise stock HK system, thanks to the BavSound stage one upgrade.

Great sound, great price!

So I finally tired of the muddled sound in my '01 E39 530 and stopped by a highly recommended car audio

store to see what it might take to improve things. For $4000 I could have one heckuva sound system--and I'm sure I would have loved it. BUT for 10% of that price and much less inconvenience, Bavsound changed my world with a set of Stage One speakers. The sound is crisp and clear--a breath of fresh air for my ears--without a price that would take my breath away.
