Power cables with a cross-section of 50 mm², which corresponds to the American marking 1/0 Gauge (AWG). A power cable with this cross-section is most often used to connect an external amplifier with a continuous current consumption of a maximum of 350 A at a cable length of 5 m and an approximate total power of the amplifier above 1500 W RMS. Depending on the length of the power cable, an amplifier with a higher current consumption can also be installed.
