Wire Length and Size:
All wiring should be carried out with 2-conductor stranded copper wire. The recommended wire
calibre is a function of the length of wire needed. We recommend 18 AWG wire for shorter runs up
to 250 feet. For longer runs, larger calibre wire must be used. The following table presents the
recommended wire calibre and length for the wiring of the system. If you need longer runs, contact
Soft dB.
