AVSL 170.310-170.316 SP800A-SP1500A PAJ SERIES - Manual (Page 8)

illustrates the appropriate minimum wire gauge for various cable lengths and speaker impedance
combinations.
When using this chart, keep in mind that two 8 Ohm parallel linked speakers will equal a 4 Ohm load
(see “looping speakers”).
Looping speakers
Running too many speakers from a single amplifier channel may result in damage to the amplifier
and/or in degraded audio performance. To calculate the combined impedance of multiple identical
speakers in parallel, please use the formula below:
Impedance of a single speaker
--------------------------------------------------------- = Amplifier load
Number of speakers connected in parallel
Refer to your power amplifiers owners manual, for information on minimum recommended load
impedance.
