3. Wire: We addressed wiring briefly, but some additional rules of thumb for 70 volt wiring are as follows: For runs less than 700 total feet and less than a 100-watt load from the amplifier use a UL Listed 18/2 gauge wire. For runs up to 1,000 feet or more than a 100-watt load, especially with higher SPL levels use a UL Listed 16/2 wire.

Second, a 70.7 volt system will rarely get to 70 volts. The voltage will depend on the audio content which varies constantly as will the current. This all has been taken into consideration if the amp is listed as a CL2 power source allowing you to use CL2 wiring. Larger amps may require Class 1 wiring and will either say so or not say anything.
70 V Sound System Myths - Professional Audio Training
https://www.prosoundtraining.com/2016/06/23/ten-70-v-system-myths/
The 70.7 volt system gets its name from the RMS (think average) voltage of a pure tone (a sine wave) whose peak voltage is 100 V, which is the highest voltage that, by code, can be present on the line. So, feed a sine wave into the system and turn it up until the “70 V” amplifier clips, and you will read 70 Vrms on the line, which is 100 Vpeak.
