Option 2: Using Power Port Plug Adapter
If your vehicle dose not have a 12V power port, use the supplied power port plug adapter for connection to your
vehicle battery.
Important:
• To avoid short circuits and any resulting damage to the sound system, the negative terminal of the vehicle’s
battery must be disconnected rst.
1. Connect the black/ground wire of the power port plug adapter to the vehicle’s metal frame or to the negative
battery terminal. Fasten the ground wire with a bolt/screw on the metal surface. Make sure the metal surface
is scraped clean with no paint, rust or dirt.
2. Connect the red wire of the power port plug adapter to the positive battery terminal.
If needed, use extension wires of 12-14 gauge for connection to the battery. Remember to install a 15A in-
line fuse (not included) and an on-off switch (not included). An on/off switch is not needed if you unplug
the power port cable after each use or if the vehicle power port is turned off with the ignition key. Refer to
