- Connect Power: Plug the power cable into the power input port on the subwoofer. Then, plug the other end of the power cable into a standard electrical wall outlet.
- Power On: Locate the power switch, usually on the back or front of the subwoofer. Turn the switch to the "ON" position. An indicator light (if present) should illuminate.
