- Use an appropriate tool to create the speaker cutout.
- Drill pilot holes for the mounting screws.
- Apply the provided gasket around the speaker opening to ensure a watertight seal.
- Connect the speaker wires and RGB illumination wires as described in the wiring section.
- Carefully place the speaker into the cutout and secure it with the provided mounting screws. Do not overtighten.
5.3. Wiring Connections
The MRGB55B speakers require two sets of connections: one for audio and one for the RGB LED illumination.
- Audio Wiring: Connect the speaker's positive (+) and negative (-) terminals to the corresponding outputs on your audio amplifier or head unit. Use the provided spade connectors for a secure connection.
- RGB Illumination Wiring: Connect the dedicated RGB wires from the speaker to a 12V power source. The included RGB wireless remote controls the color and mode of the illumination. Ensure proper polarity for the lights to function correctly.
