Strip approximately 1/2 inch (12mm) of insulation from the ends of the speaker wires. Connect the positive (+) wire from your amplifier to the red (+) terminal on the speaker, and the negative (-) wire to the black (-) terminal. Ensure a secure connection and no stray wire strands are touching.

- Secure Speaker with Rotating Cams:
The MC60 uses rotating cams for secure installation. Using a screwdriver, tighten the screws located on the front baffle of the speaker. As you tighten, the cams will rotate outwards and clamp firmly onto the ceiling material. Do not overtighten.
