Connecting the Unit
A\ CAUTION
Remove the negative (-) terminal of the
battery to avoid the risk of short-circuit
and damage to the unit.
Secure the wiring with cable clamps or
adhesive tape. To protect the wiring,
wrap adhesive tape around them where
they lie against metal parts.
Do not route wires where they will get
hot, for example where the heater will
blow over them. If the insulation heats
up, it may become damaged, resulting in
8 short-circuit through the vehicle body.
Make sure that wires will not interfere
with moving parts of the vehicle, such as
the gearshift, handbrake or seat sliding
mechanism.
Do not shorten any wires. Otherwise the
protection circuit may fail to work when it
should.
Never feed power to other equipment by
cutting the insulation of the power supply
wire to tap from the wire. The current
capacity of the wire will be exceeded,
causing overheating.
Be sure to use the special red battery wire
supplied with the amplifier and connect
directly to the battery. Use the supplied
black ground wire and connect to the
vehicle body. (The supplied special red
battery and ground wires are designed so
that the amplifier can be connected
safely.)
{18} Blue
Connect the male terminal of this wire
to the blue wire of the car stereo
(system control terminal). The female
terminal can be connected to the auto-
antenna relay control terminal.
lf the car stereo does not have a
system remote control terminal,
connect the male terminal to the power
terminal through the ignition switch.

nection instructions.
@ To prevent damage
.
Do not ground the speaker lead wire
directly or connect a negative (—) lead
wire for several speakers.
Speakers to be connected to the amplifier
should conform with the standards listed
below. Otherwise damage will be caused
to the speaker. The speaker impedance
must be 2 to 8 ohms.
This unit is for vehicles with a 12-volt
battery and negative grounding. Before
installing it in a recreational vehicle, truck,
or bus, check the battery voltage.
* Install and route the sold separately
special red battery wire supplied with the
amplifier as faraway as possible from the
speaker wires. Install and route the
battery wire, ground wire, speaker wires,
and the amplifier as faraway as possible
