Connecting The Unit

& 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.

ff you drill a hole in the engine compart-

ment to directly connect the special red

battery lead to the car battery, plug the

hole with a rubber bushing to protect the

wire. f a rubber bushing is not used, the

insulation may be damaged and a short

circuit may result due to the vibrations of

the car.

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

4 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 stiding

mechanism.

Do not shorten any leads. Otherwise the

protection circuit may fail ta 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

suppiied with the amplifier and connect

unswitched source greater than 15 A. Use

the supplied black ground wire and

connect to the vehicle body. {The sup-

plied special red battery and ground

wires are designed so that the amplifier

can be connected safely.}

OQ To prevent damage

+ Do not ground the speaker wire directly

or connect a negative {-) 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.

Connecting the Power Terminal

Be sure to use the special red battery wire

supplied with the amplifier and connect

unswitched source greater than 15 A. Use

the supplied black ground wire and

connect to the vehicle body. (The sup:

plied special red battery and ground

wires are designed so that the amplifier

can be connected safely.)

Connect the special red battery wire to the

POWER terminal (+), and the black ground

wire to the GND terminal (~).

battery and negative grounding. Before

installing it in a recreational vehicle, truck,

or bus, check the battery voitage.

install and route the 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 from the

antenna, antenna cable and tuner.

Connecting the Speakers

The speaker output mode can be two

channel (stereo), one-channel (mono), or

three-channel (stereo + mono). To connect

the speaker wires to suit the mode. Connect

the speakers according to the figure below.
