When using a single subwoofer, you MUST use a pair of stereo low-level leads from your preamplifier’s outputs. When using two subwoofers, one for the left and another for the right channel, connect the left preamplifier output to BOTH the left and right LOW-LEVEL INPUTS of the subwoofer used for the left channel by using a Female-to-Male “Y” connector at the subwoofer’s input and the right channel preamplifier output to both jacks of the right channel subwoofer in the same manner (see Figure 4). If the preamplifier has a mono subwoofer output, you’ll also need a Male-to-Female “Y” connector to split the mono signal to the subwoofer pair (see Figure 4).
