CONNECTING YOUR SUBWOOFER (CONT.)

The subwoofer may be connected to your system using the HIGH-LEVEL INPUTS (4) on the plate located on the rear panel of the subwoofer. Use speaker wire, maintaining proper polarity (+ to + and – to –). Attach the speaker wire to the left and right HIGH-LEVEL INPUTS on the subwoofer and the other ends to the proper left and right OUTPUTS on your amplifier or receiver (see Figure 5).

If you plan to use two subwoofers (one for the left and the other for the right channel) connect wires from the left and right OUTPUT on your power amplifier or receiver and attach the other ends to the corresponding HIGH-LEVEL INPUTS on each subwoofer. Observe polarity (see Figure 6).
