4.2 Wiring Connections
The sound bar requires a power, ground, and accessory wire connection. It is recommended to connect directly to the vehicle's battery for optimal performance.
- Power (Red Wire): Connect the red power wire to the positive (+) terminal of your vehicle's 12V battery. Ensure an inline fuse (not included, recommended 15A) is installed close to the battery for protection.
- Ground (Black Wire): Connect the black ground wire to a clean, unpainted metal surface on the vehicle's chassis or directly to the negative (-) terminal of the battery.
- Accessory/Remote (Blue Wire): Connect the blue accessory wire to a switched 12V source (e.g., ignition switch) that turns on and off with the vehicle. This will allow the sound bar to power on/off with your vehicle.
- Secure Wiring: Route all wires safely away from moving parts, heat sources, and sharp edges. Use zip ties or cable clamps to secure the wiring.
