Please Read Before Purchasing
This package is designed for various compatible BMW models, not every BMW vehicle.
Factory tweeter locations, mounting arrangements and audio systems can differ between BMW models, production years and trim levels.
The Type 1 mounting configuration must match your vehicle's original speaker arrangement. A compatibility check is recommended before purchase.
Some BMW factory audio configurations may not have dedicated tweeter mounting locations. Additional components or modifications may therefore be required for those vehicles.
These packages are primarily intended for professional installation and experienced installers, although some may suit confident DIY users with appropriate technical knowledge.
Minor modifications may be necessary depending on the vehicle's exact configuration.
Important: Tweeters require appropriate high-frequency filtering. The package listing does not identify an included crossover, so crossover compatibility should be confirmed before installation.
Installation fees are not included in the online product price.
Who This Package Is For
This package is intended for BMW owners who want to replace compatible factory tweeters with HELIX Ci3 high-frequency speakers while retaining their existing audio-system architecture.
It is particularly suitable for customers seeking a targeted high-frequency speaker upgrade rather than a complete speaker, amplifier or DSP system replacement.
Installation & Tuning Notes
The original factory tweeters are removed and replaced using the supplied vehicle-specific mounting adapters.
The tweeters and mounting adapters are supplied as separate components within the matched upgrade package.
Before installation, confirm the factory mounting arrangement, wiring connections, amplifier compatibility and appropriate high-frequency filtering.
Where the vehicle uses a DSP amplifier, professional tuning may help integrate the replacement tweeters with the existing midrange and woofer speakers.
Professional installation is recommended to ensure correct mounting, electrical integration and reliable performance.
