Setup and Installation
Proper installation is crucial for optimal performance and durability. If you are unsure about any steps, consult a professional installer.
- Choose Mounting Location: Select a flat, stable surface on your boat, ATV, UTV, or vehicle that can accommodate the speaker's dimensions (5.6" cutout, 2.56" mounting depth). Ensure there is sufficient clearance behind the mounting surface.
- Prepare Mounting Hole: Use the provided cutting template to mark and cut the speaker opening. Ensure the hole is clean and free of debris.
- Speaker Wiring: Connect the speaker wires to the appropriate terminals on the speaker. The RKL65MBW speakers have a 4 Ohm impedance. Ensure correct polarity (positive to positive, negative to negative) for all speakers in your system.
- LED Wiring: The integrated LED lights are powered via the speaker wire. No additional wiring is typically required for basic LED function (red or blue beat-sync).
- Mount Speakers: Insert the speakers into the prepared openings. Secure them using the provided stainless steel mounting screws. Do not overtighten.
- Install Grilles: Choose between the black or white detachable grilles and snap them into place.

Operating Instructions
Once installed, the RKL65MBW speakers are ready for use with your audio system.
- Audio Playback: Connect your audio source (e.g., marine stereo, amplifier) to the speakers. Ensure the audio source is powered on and playing music.
- LED Lighting: The speakers feature beat-sync LED lights that flash red or blue in rhythm with the music. This function is automatic and does not require separate control. The color (red or blue) is typically pre-set or alternates based on the speaker's internal logic.
- Volume Control: Adjust the volume directly from your connected audio source.

Maintenance
The Rockville RKL65MBW speakers are designed for durability in harsh environments. Regular maintenance helps preserve their condition and performance.
