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.
CAUTION
!
To prevent water from entering the amplifier,
attach a cover or cap to each terminal when
not in use.
!
Never shorten any wires, the protection circuit
may malfunction.
!
Never wire the speaker negative cable directly
to ground.
!
Never band together multiple speaker
’
s nega-
tive cables.
!
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 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.
Connecting the speakers
This amplifier can be connected to two speak-
ers in parallel. Connect the speaker leads to
suit the mode according to the figure shown
below.
Precautions for parallel connection
!
When wiring two speakers in parallel, make
sure that the synthetic impedance is from
1
W
to 8
W
to prevent the amplifier from
catching fire, generating smoke and/or
being damaged.
!
When connected in parallel with the syn-
thetic impedance less than 1
W
, as a nor-
mal function, this amplifier may
automatically be set on mute if outputting
high volume sound. Turn down the volume
until the mute function is canceled.
