BAVSOUND S1 Plug & Play BMW 3 Series E36 Speaker Upgrade Kit with Harman Kardon

BAVSOUND S1 Plug & Play BMW 3 Series E36 Speaker Upgrade Kit with Harman Kardon

Get unbelievable, crystal clear sound. Just by replacing your BMW's speakers.

We took your factory BMW speakers and re-engineered our upgrade for one thing: clarity. So you can simply swap your original speakers for ours without changing anything else in your audio system, and the result is smooth, natural, yet unbelievably detailed reproduction of your favorite music.

PLAY YOUR MUSIC LOUDER. AND ENJOY EVERY NOTE: We engineered the Stage One speakers to produce higher quality sound: a wider range and more balanced reproduction of the bass and treble you are 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 volumes much louder than your factory speakers.

DESIGNED TO FIT AND OPERATE JUST LIKE YOUR FACTORY SPEAKERS, ONLY BETTER: We engineer our speakers with the same unique size, shape, connectors, impedance, and efficiency as your factory speakers. That means installation is as simple as unbolting your factory speakers and bolting ours in, and it's totally reversible, too. No one will ever know you've upgraded your audio system except you. Unless, of course, they hear it.

INCLUDES EVERYTHING YOU NEED FOR CRYSTAL CLEAR SOUND, EXCEPT TOOLS: Replaces every speaker in your BMW (except subs), and includes everything you need except basic tools, available separately.

100 DAY IN CAR TRIAL, FREE RETURNS! - Install, audition, and fully experience your new audio gear. If you don't love it, we'll cover return shipping and give you a full refund (U.S. customers only).

100% PLUG & PLAY INSTALLATION: Simply unbolt, unplug, and remove your factory speakers and plug ours in. It's that simple. Really. (NOTE: 1996-1999 BMW 3 SERIES / M3 has additional steps, please review installation guides before purchase)

SO SIMPLE, YOU CAN DO IT YOURSELF: Ever put together IKEA furniture? Then you can install the Stage One. Includes step-by-step instructions, and is designed to be easy enough that anyone can install it in just a few hours.

4 YEAR 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 upgrades are backed with our industry leading 4 year limited warranty. So if something breaks, send it back. We'll replace it at no charge.
