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.

[19] Speaker output terminals

See the "Connecting the Speakers and

Input wires" section for speaker con-

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
