Recommended wire sizes are the minimum gauge calculated not to lose more than 10% of total power amplifier output. Note that the lower the gauge, the larger the wire size. Amplifier power refers to rated RMS output power per channel. These are merely recommendations for wire size. Please refer to the owners manual for all of the equipment involved for the manufacturers requirements.
* refers to no wire available for that speaker cable length that will not exceed the 10% loss.
