Unfortunately, Your BMW is NOT the Ultimate Sound Machine...

One of the first things most BMW owners notice about their vehicles is the poor performance of the BMW audio system. There is no clear definition at any volume level. The high frequency range is muffled and distant and midrange is harsh. Over time, the audio system can be "fatiguing." In short, listening to music in your BMW can be a VERY disappointing experience.

Because we believe life is better with great music, BSW developed the Stage 1 Audio Upgrade to dramatically enhance the performance of your BMW's audio system.

Delivers striking clarity and definition -- and incredible musical detail -- from an amazingly easy to install Plug and Play system.

100% Stealth Your interior will appear unchanged, and only you and your passengers will know you've upgraded your audio system.	Greatly improved musical detail & presence Uses coated natural fiber drivers and silk tweeters that remain distortion free at higher volumes and provides accurate, natural sound.
Plug n'Play! Features plug and play connectors on each speaker, so all you have to do is remove your original speakers then mount and plug the new ones in.	Wider musical range Produces higher quality sound and a wider range of the midrange and treble you're currently missing. (For more bass response, we recommend a BSW subwoofer system).
