vehicle's chassis.
Battery Lead (sold separately)
Be sure to add an External Fuse (e.g. Fuse Block,
Circuit Breaker) with the battery lead as close as
possible to the battery's positive (+) terminal.
This fuse will protect your vehicle's electrical
system in case of a short circuit. See below for
appropriate fuse value requirement:
90 amp fuse
• For details on the wires size to be used, refer to
the supplied "Cautions on Power Supply Wires
Connection" and "Cautions on Power Supply
Wires" (page 19), and then use the wire of
the specified size.
Remote Turn-On Lead (sold separately)
Connect this lead to the remote turn-on
(positive trigger, (+) 12 V only) lead of your head
unit. If a remote turn-on lead is not available, see
"CONNECTION CHECK LIST" section on
page 7 for alternative method.
• When connecting the speaker output leads of
the head unit to this unit with a Speaker-RCA
Conversion cable (sold separately), you do not
need to connect the remote turn-on lead,
owing to the "REMOTE SENSING" function of
this unit. However, the "REMOTE SENSING"
function may not work depending on the
signal source connected. In such a case,
connect the remote turn-on lead to an
incoming power supply cord (accessory
power) in the ACC position.
Ground Lead (sold separately)
Connect this lead securely to a clean, bare metal
spot on the vehicle's chassis. Verify this point to
be a true ground by checking for continuity
between that point and the negative (–)
terminal of the vehicle's battery. Ground all your
audio components to the same point on the
chassis to prevent ground loops while keeping
wire length as short as possible.
• For details on the wires size to be used, refer to
the supplied "Cautions on Power Supply Wires
Connection" and "Cautions on Power Supply
Wires" (page 19), and then use the wire of
the specified size.
