About Power supply wires
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. See below for wire gauge recommendations
for distribution block connection to battery and ground
(depends upon wire length necessary):

keeping wire length as short as possible.
Ensure that you install a correctly-rated in-line fuse on the
power cable near the battery positive post.
Cautions on wire lead connections
When using third-party wire cables (power supply wire), use
the supplied screws to simplify the connection. Refer to the
description below for the proper procedure. If you are in doubt
about how to make this connection, consult your dealer.
1. Check the wire size.
• Required Wire Size
– Battery Lead/Ground Lead ........4 AWG (21 mm
– Remote Turn-On Lead ..................12 AWG (3 mm
• If the wire gauge used is unknown, ask your dealer.

2. Remove the insulation from the ends of the wire
leads by about 7 – 10 mm (9/32" – 13/32").
7 – 10 mm
(9/32" – 13/32")
Twist the tip of
wire leads
NOTES:
• If length of the exposed wire is too short, a poor connection
may occur causing operation failure or sound interruption.
• On the other hand, if the length is too long, an electrical
short-circuit may occur.
3. Tighten the screw to secure the lead.
Before making this connection, use insulated shrink
tubing to cover any exposed wire extending beyond
the terminal.
