If the loudspeaker has two NL or AP type connectors, they are wired in parallel so you can "Y-connect" multiple loudspeakers together to a single amplifier channel. This is commonly known as "daisy chaining." This will lower the load impedance on the amplifier. This can be calculated by this formula:

(Nominal impedance single loudspeaker) / (number of loudspeakers daisy chained)

The proper connections are marked for each terminal on the loudspeaker input label, normally as "+" and "-".

The proper conductor size (wire gauge) to use for the loudspeaker cable is primarily a function of the wire length. The general rule is that lower resistance, in relation to the loudspeaker's impedance, is better. To achieve this, use larger conductor sizes for longer lengths of cable and for lower impedance loudspeaker loads.

To 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, over 100 feet at 4 ohms, and over 50 ft at 2 ohms, the conductor sizes required for an adequate damping factor are rarely practical for physical and cost reasons. While it is recommended to avoid such situations the most practical wire gauge for these situations is 10 AWG / 6 mm2
