Before connecting
the
amplifier
A wARNING
• Secure the wiring with cable clamps
or
adhe-
sive tape.
To
protect the wiring, wrap sections
in contact with metal parts in adhesive tape.
• Never cut the insulation of the power supply
to feed power to other equipment. Current ca-
pacity of the wire is limited.
A
cAUTION
• Never shorten any wires, the protection
circuit
may malfunction.
• Never ground speaker wire directly or band to-
gether multiple speakers' negative
(8)
lead
wires.
• If the system remote control wire of
the
ampli-
fier
is
connected to the power terminal via the
ignition switch
(12
V
DC),
the amplifier will
re-
main
on
with the ignition whether the car
stereo
is
on or off, which may exhaust battery
if the engine
is
at rest or idling.
• Install and route the separately sold battery
wire
as
far
as
possible from the speaker wires.
Install and route the separately sold battery
wire, ground wire, speaker wires and the am-
plifier
as
far away
as
possible from the anten-
na, antenna cable and
tuner.[!)
