What You Can Expect From A Bavsound Purchase
Love Of Sound
Exceptional Audio Fidelity
We took your factory 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.
Easy OEM Swap
Same Dimensions, Higher Quality Throughout.
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.
2 Hour Install
No Expensive Install Process
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.
Music As Intended
Enjoy music as the artist intended.
We engineered 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 car's factory speakers, we use proven audio technology: woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters.
Full Purchase Support
Flexible Purchase Options, 100 Day Returns, & 4 Year Warranty
Pay-in-4 available, plus try it for 100 days in your car. 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).
Now that's an easy purchase.
