Unfortunately, Your BMW is NOT the Ultimate Sound
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. To address these problems, BSW developed
the Stage 1 Audio Upgrade:

The Stage 1 Audio Upgrade delivers striking clarity and definition, more musical detail and life, and improved bass dynamics simply and affordably.
When we designed our Stage 1 Audio Upgrade, we made sure the system met several key requirements and features:
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.
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.
More highs, more lows
