Power Connection

Option1: Using Power Port

If your vehicle has a 12V power port, directly connect the sound bar to your vehicle for power connection.

1. 

Insert the 12V power port plug of the sound bar into your vehicle power port. When the power supply is 

connected, the power LED indicator illuminates on the power port plug.

Note:

 To avoid battery drain, it is recommended to unplug after each use (if the port power is not switched 

off with the ignition key).

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 bar, the negative terminal of the vehicle battery 

must be disconnected first.

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 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 sound bar after each use or if the vehicle power port is turned off with the ignition key. Refer to 

the illustration.

3. 

Insert the power port plug of the sound bar into the power port plug adapter.

When the power supply is connected, the power LED indicator illuminates on the power port plug.
