Cautions on Power Supply Wires Use the specified wire size according to the total fuse capacity of the amplifier to be installed and the wire length. For details on the wire size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and the following connection example. Connection example when installing an amplifier alone • When the wire length from the amplifier to the vehicle's battery is 5 m Wire size used for (A): 4 AWG/21 mm2 • External Fuse capacity: Make it equal to or larger than the fuse capacity of the amplifier R-A75M: equal to or larger than 80 A R-A60F: equal to or larger than 60 A Amplifier (A) External Fuse Vehicle's chassis Vehicle's battery Connection example when installing two amplifiers with a fuse capacity of 80 A and one amplifier with 60 A • When the wire length from each amplifier to the distribution block is 1 m Wire size used for (B): 4 AWG/21 mm2 • When the wire length from the distribution block to the vehicle's battery is 4 m Wire size used for (C): 1/0 AWG/53 mm2 • External Fuse capacity: Make it equal to or larger than total fuse capacity of the number of amplifiers installed 80 A + 80 A + 60 A = equal to or larger than 220 A (B) (C) Amplifier (e.g. 80 A) Amplifier External Fuse Distribution block Vehicle's battery (e.g. 80 A) Amplifier Vehicle's chassis (e.g. 60 A) NOTE: • If the length of the power and ground cables exceed 1 m, or if you connect more than one amplifier, a distribution block should be used. 20-EN
