If the loudspeaker has two connectors for the same mode of operation, they are wired in parallel so you can “daisy chain” multiple loudspeakers together to a single amplifier channel.

4 . 4 L o u d s p e a k e r C a b l e

To minimize power losses and provide a sufficient damping factor (DF) for low frequency drivers, use loudspeaker cable with conductor sizes per the following chart. For cable lengths over 200 feet at 8 ohms and over 100 feet at 4 ohms, the conductor sizes needed for an adequate damping factor are rarely practical for physical and cost reasons. For these situations, 10 AWG / 25 metric gauge are recommended as the most practical sizes.
