Setting the Unit
Gain Control
Adjusting the gain controls A and B will
help match the output of the car stereo to
the Pioneer amplifier. Normally, set the
gain controls to the "NORMAL" posi-
tion. If the output is low, even when the
volume of the car stereo is turned up,
turn these controls clockwise. If there is
distortion when the volume of the car
stereo is turned up, turn these controls
counter-clockwise.
· If you only use one input plug, set the gain
controls for speaker outputs A and B to the
same position.
· 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.
Cut Off Frequency Control
Combining LPF/HPF/BPF and
LOW/HIGH select switch settings lets
you select between cut off frequencies
from 40 to 120 Hz and 3k to 9k Hz.
(Example: LPF and HIGH)
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
When the unit does not operate properly,
contact your dealer or the nearest autho-
rized PIONEER Service Station.
WARNING
· Always use the special red battery and ground
wires ([RD-223]
× 2), which are 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
speakers if the fuse of the separately sold battery
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
speakers, 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 speakers.
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.

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

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 idle.
· 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 1 to 8 ohms. But in case of two-channel and
other bridge connections, the speaker impedance
must be 2 to 8 ohms.
· 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 important 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. Take special care not to
block the cooling fan side of the amplifier.
--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
screwdriver so they make marks
where the installation holes are to be
located.
2. Drill 2.5 mm diameter holes at the
point marked, and install the ampli-
fier, either on the carpet or directly
to the chassis.

PRECAUCIÓN
· Quite el terminal negativo (­) de la batería para
evitar riesgo de cortocircuitos y daño a la unidad.
· Asegure el alambrado con abrazaderas de cable o
cinta adhesiva. Para proteger el alambrado,
envuelva cinta adhesiva alrededor de ellos en
donde contacta con partes metálicas.
· No tienda cables por donde puedan calentarse, por
ejemplo donde el calentador sople sobre ellos. Si
la aislación se calienta, podría resultar dañada,
resultando en cortocircuito a través de la carro-
cería del vehículo.
· Asegúrese que los alambres no interfieran con
partes móviles del vehículo como la palanca de
cambios, el freno de mano o el mecanismo de
deslizamiento de los asientos.
· No corte ningún cable. De otra manera, el circuito
de protección podría no funcionar cuando debiera.
· Nunca alimente otro equipo cortando la aislación
del cable de alimentación y conectándolo al cable.
La capacidad de corriente del cable será excedida,
causando sobrecalentamiento.

Para prevenir de daños
· No conecte a tierra (masa) el cable del altavoz
directamente ni conecte un cable negativo (­) a
varios altavoces.
· Esta unidad es para vehículos con una batería de
12 voltios y terminal negativo a tierra. Antes de
instalar en un vehículo de recreación, camión u
ómnibus, verifique el voltaje de la batería.
· Si el sistema estereofónico del coche está funcio-
nando por un largo período de tiempo mientras el
motor permanece inactivo o en marcha al ralentí,
la batería puede agotarse. Apague el estéreo de
automóvil cuando el motor se encuentre funcio-
nando en marcha al ralenté o permanece in activo.
· Si el cable del control remoto del sistema del
amplificador se conecta al terminal de ali-
mentación a través del interruptor de encendido
(12 V de CC), el amplificador estará siempre acti-
vado cuando el encendido está activado, sin con-
siderar de si el estéreo de automóvil se encuentra
activado o desactivado. Debido a esto, la batería
puede agotarse si deja el motor funcionando en
marcha al ralentí o permanece inactivo.
· Los altavoces a ser conectados al amplificador
deben estar conforme con las normas listadas
debajo. Si no cumplen con las normas, pueden
combustionar, emitir humos o dañarse. El impe-
dimiento altavoz debe estar de 1 a 8 ohms, pero
en caso de que dos canales y otros puentes
contecten, el impedimiento de altavoz debe estar
de 2 a 8 ohms.
· Instale y coloque el cable de batería vendido sepa-
radamente lo más alejado posible de los cables de
los altavoces. Instale y coloque el cable de batería
y cable de tierra vendidos separadamente, los
cables de los altavoces, y el amplificador lo más
alejados posible de la antena, cable de antena y
sintonizador.
· Los cables para esta unidad y aquéllas para las
unidades pueden ser de colores diferentes aun si
tienen la misma función. Cuando se conecta esta
unidad a otra, refiérase a los manuales de insta-
lación de ambas unidades y conecte los cables
que tienen la misma función.
