Power cables with a cross-section of 6 mm², which corresponds to the American marking 10 Gauge (AWG). A power cable with this cross-section is most often used to connect an external amplifier with a continuous current consumption of maximum 20 A at a cable length of 5 m and an approximate total amplifier power of up to 200 W RMS. Depending on the length of the power cable, an amplifier with a higher current consumption can also be installed.
