Setup
Mounting: The CF-X8PRO speakers feature die-cast adjustable clamps that allow for 360-degree rotation, accommodating mounting bars from 1" to 2" in diameter. Ensure secure fastening using the provided hex wrenches and screw fastening glue. Proper mounting is crucial for optimal sound dispersion and speaker stability.
Wiring: The integrated RGB LED lights require a separate LED BTC (Bluetooth Controller) for full functionality and color control. Connect the 6 core wires from the speaker to the appropriate outputs on the LED BTC controller. For audio, connect the speaker wires to your amplifier, ensuring correct polarity and impedance matching (4 Ohms).
