This manual provides installation and usage instructions for the Focal Inside MBZ speaker series. Before beginning, it is essential to verify your vehicle's compatibility online at www.focal-inside.com. The manual includes specific wiring diagrams for woofer protection and installation recommendations to ensure optimal performance.


Important Safety Instructions
- Hearing Protection: Avoid listening to loudspeakers at high volumes for long periods. Exposure to volumes over 85 dB for more than one hour can cause irreparable hearing damage.
- Secure Installation: If a subwoofer is installed in your vehicle, ensure it is firmly secured to the floor or chassis to prevent it from becoming a projectile in the event of an accident.
- Cables and Fuses: Use provided cables and harnesses as instructed without modification. If a fuse is included, replace it only with one of the same rating.
Installation Recommendations

- Space Check: Before cutting, check the available space in the vehicle to fit the speakers. Ensure there is enough space between the speaker and the protection grille.
- Cleanliness: Ensure the speaker is clean from debris and metallic particles, especially after drilling. Clean the area before mounting.
- Running-in Period: To ensure complex mechanical elements work in harmony, allow a running-in period of a few weeks. Run the system with medium volume settings using music with full bandwidth (sub-bass through treble).
- Installation Tutorials: Installation details vary by model; refer to the online installation videos at www.focal.com/focal-inside/videos/.
