- Power Connection: Connect the main power cable (typically 4-gauge or larger) to the amplifier's +12V terminal and to the positive terminal of the boat's battery. Include an appropriate fuse within 18 inches of the battery.
- Ground Connection: Connect a ground cable of the same gauge as the power cable to the amplifier's GND terminal and to a clean, solid metal point on the boat's chassis or directly to the battery's negative terminal.
- Remote Turn-On: Connect a remote turn-on wire from your head unit or switch to the amplifier's REM terminal. This wire signals the amplifier to turn on and off with your audio system.
- RCA Inputs: Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA input jacks (CH1/2, CH3/4, CH5/6).
- Speaker Outputs: Connect your marine speakers to the amplifier's speaker output terminals, ensuring correct polarity (+ to + and - to -). The amplifier supports various channel configurations.
Ensure all connections are secure and insulated to prevent short circuits and corrosion.
3. Operating Instructions
