The first step is to determine where and how you will run the speaker wires from the receiver to the speakers. In most cases, the wires will run on the floor along the baseboards. Measure the distance between the receiver and speakers and make sure you have enough speaker wire.
Connect the left and right channel speaker wires to the ‘Main’ or ‘Front’ speaker outputs on the back panel of the receiver or amplifier, then run the wires to the terminals on the back of each speaker. Make sure you connect the left channel output of the receiver to the left channel speaker and the same for the right channel. Correct speaker phasing is very important for the best sound.
