CAUTION:

To prevent damage and/or injury

• Do not ground the speaker wire directly or con-

nect a negative (–) lead wire for several speakers.

• This unit is for vehicles with a 12-volt battery and

negative grounding. Before installing it in a recre-

ational vehicle, truck or bus, check the battery

voltage.

• If the car stereo is kept on for a long time while

the engine is at rest or idling, the battery may go

dead. Turn the car stereo off when the engine is at

rest or idling.

• If the system remote control wire of the amplifier

is connected to the power terminal through the

ignition switch (12 V DC), the amplifier will

always be on when the ignition is on— regardless

of whether the car stereo is on or off. Because of

this, the battery could go dead if the engine is at

rest or idling.

• Speakers to be connected to the amplifier should

conform with the standards listed below. If they

do not conform, they may catch fire, emit smoke

or become damaged. The speaker impedance must

be 2 to 8 ohms for stereo connection, and 4 to 8

ohms for monaural and other bridge connection.

• Install and route the separately sold battery wire

as far away as possible from the speaker wires.

Install and route the separately sold battery wire,

ground wire, speaker wires and the amplifier as

far away as possible from the antenna, antenna

cable and tuner.

• Cords for this product and those for other prod-

ucts may be different colors even if they have the

same function. When connecting this product to

another product, refer to the supplied Installation

manuals of both products and connect cords that

have the same function.

Connecting the Unit

CAUTION

• Disconnect 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 it 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 a short-circuit through the vehicle

body.

• Make sure that wires will not interfere with mov-

ing parts of the vehicle, such as the gearshift,

handbrake or seat sliding mechanism.

• Do not shorten any wires. Otherwise the protec-

tion 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.

• Never replace the fuse with one of greater value

or rating than the original fuse. Use of an improp-

er fuse could result in overheating and smoke and

could cause damage to the product and injury

including burns.

After making all other connections at the amplifier,

connect the battery wire terminal of the amplifier to

the positive (+) terminal of the battery.

See the “Connecting the

Speaker wires” section

for speaker connection

instructions.

System remote control wire (sold separately)

Connect the male terminal of this wire to the system remote control

terminal of the car stereo (SYSTEM REMOTE CONTROL). The

female terminal can be connected to the auto-antenna relay control

terminal. If the car stereo does not have a system remote control ter-

minal, connect the male terminal to the power terminal through the

ignition switch.

Speaker Channel Speaker Type Power

Two-channel

Setting the Unit

Gain Control

If the sound level is too low, even when

the volume of the car stereo used along

with this power amplifier is turned up,

turn gain control on the front of the

power amplifier clockwise. If the sound

distorts when the volume is turned up,

turn the gain control counter-clockwise.

• When using with an RCA equipped car

stereo (standard output of 500 mV), set to

the NORMAL position. When using with

an RCA equipped Pioneer car stereo with

max. output of 4 V or more, adjust level to

match the car stereo output level.

• If you hear too much noise when using the

speaker input terminals, turn the gain

control counter-clockwise.

Power Indicator

The power indicator lights when the

power is switched on.
