Power cables with a cross-section of 16 mm², which corresponds to the American marking 6 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 60 A with a cable length of 5 m and an indicative total power of the amplifier up to 650 W RMS. Depending on the length of the power cable, an amplifier with a higher current consumption can also be installed.
