Caution: To avoid any damage to the subwoofer or amplifier, disconnect power from your components before making any connections. Do not connect to both the subwoofer out or pre-out jacks and the speaker terminals at the same time. Connecting to Subwoofer Out/Pre-out Terminals Use this connection if your amplifier/receiver has jacks labeled SUBWOOFER OUT or PRE-OUT.

Turn on your amplifier/receiver and an audio source (such as a radio, CD player, or turntable). 3. Begin playing the audio source and adjust the amplifier and speaker’s overall volume to a comfortable level.
Replacing the Fuse If your subwoofer stops operating properly, you might need to replace the fuse with a slow operating, type 2A / 250V fuse. Caution: Before replacing the fuse, disconnect the subwoofer’s AC plug and turn off the amplifier/receiver. Do not use a fuse with ratings other than those specified. To replace the fuse, use a screwdriver to turn the fuse holder (located on the back of the subwoofer) counterclockwise.
