2. Wiring Connections

This diagram illustrates the wiring connections. The three main wires (Ignition Wire, Positive Wire, Negative Wire) must all be connected to the battery for full functionality. If only red and black wires are connected, only the alarm function will work, and music playback will not. The white wire is an antenna and does not need to be connected, or it can be connected to the metal frame of your motor vehicle.
- Power Connection: Connect the power harness to your vehicle's 12V DC power source. Ensure the red (Positive), black (Negative), and yellow (Ignition) wires are all correctly connected to the battery for full system functionality. If only red and black are connected, only the alarm will function.
- Speaker Connection: Connect the four speaker wires from the main unit to your speakers. Ensure correct polarity (+/-) for optimal sound.
- Antenna: The white wire serves as an antenna. It can be left unconnected or connected to the metal frame of your vehicle for improved FM reception.
- Remote Control: Connect the wired remote control to the designated port on the main unit.
