Setting the Unit

Bass Level 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 bass level control on the front of the

power amplifier clockwise. If the sound

distorts when the volume is turned up,

turn the bass level control counter-clock-

wise.

• 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.

• When you want to boost bass, turn the bass

level control clockwise.

Power Indicator

The power indicator lights when the

power is switched on.

BFC (Beat Frequency Control) Switch

If you hear a beat while listening to an

AM broadcast with your car stereo,

change the BFC switch using a small

standard tip screwdriver.

Thank you for purchasing this PIONEER

product. Before attempting operation, be

sure to read this manual.

In case of trouble

rized PIONEER Service Station.

About This Product

This product is a class D amplifier for the

subwoofer. If both L (left) and R (right)

channels are connected to the RCA input

of this product, output is mixed because

this product is a mono amplifier.

WARNING

• Always use the special red battery and ground

wire [RD-223], which is sold separately. Connect

the battery wire directly to the car battery positive

terminal (+) and the ground wire to the car body.

• Do not touch the amplifier with wet hands.

Otherwise you may get an electric shock. Also, do

not touch the amplifier when it is wet.

• For traffic safety and to maintain safe driving

conditions, keep the volume low enough so that

you can still hear normal traffic sound.

• Check the connections of the power supply and

subwoofer if the fuse of the separately sold bat-

tery wire or the amplifier fuse blows. Detect the

cause and solve the problem, then replace the fuse

with another one of the same size and rating.

• To prevent malfunction of the amplifier and sub-

woofer, the protective circuit will cut the power

supply to the amplifier (sound will stop) when an

abnormal condition occurs. In such a case, switch

the power to the system OFF and check the

connection of the power supply and subwoofer.

Detect the cause and solve the problem.

• Contact the dealer if you cannot detect the cause.

• To prevent an electric shock or short-circuit

during connection and installation, be sure to

disconnect the negative (–) terminal of the battery

beforehand.

• Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier. Be

sure to protect all cables and important equipment

such as fuel lines, brake lines and the electrical

wiring from damage.

Connecting the Power Terminal

• Always use the special red battery and ground

wire [RD-223], which is sold separately. Connect

the battery wire directly to the car battery positive

terminal (+) and the ground wire to the car body.

1. Pass the battery wire from the

engine compartment to the interior

of the vehicle.

• After making all other connections to the

amplifier, connect the battery wire terminal of

the amplifier to the positive (+) terminal of

the battery.

2. Twist the battery wire, ground wire

and system remote control wire.

3. Attach lugs to wire ends. Lugs not

supplied.

• Use pliers, etc., to crimp lugs to wires.

4. Connect the wires to the terminal.

• Fix the wires securely with the terminal

screws.

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.

To prevent damage

• 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.

• Connect a subwoofer with a 380 W or larger nom-

inal input and an impedance between 1 and 8

ohms to the amplifier. If the nominal input and

impedance are out of the above ranges, the sub-

woofer may catch fire, emit smoke or become

damaged.

• 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

• Do not install in:

—Places where it could injure the driver or pas-

sengers if the vehicle stops suddenly.

—Places where it may interfere with the driver,

such as on the floor in front of the driver’s

seat.

• Make sure that wires are not caught in the sliding

mechanism of the seats, resulting in a short-cir-

cuit.

• Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier.

Protect all cables and important equipment such

as fuel lines, brake lines and electrical wiring

from damage.

• Install tapping screws in such a way that the

screw tip does not touch any wire. This is impor-

tant to prevent wires from being cut by vibration

of the car, which can result in fire.

• To prevent electric shock, do not install the ampli-

fier in places where it might come in contact with

liquids.

• To ensure proper installation, use the supplied

parts in the manner specified. If any parts other

than the supplied ones are used, they may damage

internal parts of the amplifier, or they may

become loose causing the amplifier to shut down.

To prevent malfunction

• To ensure proper heat dissipation of the amplifier,

be sure of the following during installation.

—Allow adequate space above the amplifier for

proper ventilation.

—Do not cover the amplifier with a floor mat or

carpet.

• Do not install the amplifier near a door where it

may get wet.

• Do not install the amplifier on unstable places

such as the spare tire board.

• The best location for installation differs with the

car model and installation location. Secure the

amplifier at a sufficiently rigid location.

• Make temporary connections first and check that

the amplifier and the system operate properly.

• After installing the amplifier, confirm that the

spare tire, jack and tools can be easily removed.

Example of installation on the floor

mat or on the chassis

1. Place the amplifier where it is to be

installed. Insert the supplied tapping

screws (4 18 mm) into the screw×

holes. Push on the screws with a
