■ Connections

• Connect the input terminals at the rear of the speakers to the speaker output terminals of the amplifier

with the speaker cable.

• Connect the (+) terminals on the amplifier and the speakers using one side of the cable. Connect the

(–) terminals on both components using the other side of the cable.

• Connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals,

making sure not to reverse the polarity (+, –). If one speaker is connected with reversed polarity, the sound

will be unnatural and lack bass.
