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.
CAUTION
• Never replace the fuse with one of greater value
or rating than the original fuse. Use of an
improper fuse could result in overheating and
smoke and could cause damage to the product
and injury including burns.
• Use the supplied hexagonal wrench to tighten
screws when fastening wires to the terminal or
when changing the direction of the badge. The
use of a long, commercially available hexagonal
wrench can cause excessive torque to be applied
possibly resulting in damage to terminals and
wires.
• Handling the cord on this product or cords associated with accessories sold with the product may
expose you to chemicals listed on proposition 65
known to the State of California and other governmental entities to cause cancer and birth
defects or other reproductive harm. Wash hands
after handling.
• Always use the recommended battery wire and
ground wire, 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
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
subwoofer, 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.
• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface
and the surface of any attached speakers could
become hot to the touch and minor burns could
result.

Setting the Unit
MODE SELECT Switch
You can select amplifier’s sync mode from
MASTER, SYNC and SYNC INV. Set the
MODE SELECT switch to the MASTER position when using one amplifier only. When using
synchronously connecting two or more of these
amplifiers in combination, set the first amplifier
to MASTER, and set the remaining amplifiers to
SYNC or SYNC INV according to the manner in
which they are connected. The only time the
amplifier is switched to the SYNC INV mode is
when amplifiers are synchronously connected
with the ex. bridge.
When switching to the SYNC or SYNC INV
mode, remove the screw and stopper. Remove
the screw and stopper after checking that
connections are correct. See the “Connecting the
Speaker Wires” section for details on the MODE
SELECT switch.
Bass Boost Frequency Control
You can select a bass boost frequency
from 40 Hz to 120 Hz with the bass
boost control.
Terminal Cover
Before setting up the unit, unfasten the screws with a 4 mm
hexagonal wrench and remove
the terminal cover.
Bass Boost Level Control
You can select a bass boost level from
0, 6, 9 and 12 dB.
For instruction of connecting the bass
boost remote control to the amplifier,
see the “Connection Diagram” section.

Cut Off Frequency Control
for LPF
You can select a cut off frequency
from 40 Hz to 240 Hz.
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 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.
• For synced amplifier’s gain control, see the “Setting the Gain for synced amplifier” sec-
tion.
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.

Setting the Gain properly
• This unit is equipped with a protective function to
prevent malfunction of the unit itself and speakers
from too much output, improper use or improper
connection.
• When outputting sound at high volume etc., this
function will cut off the sound output in a few
seconds. But this is not a malfunction. When you
turn down the volume of the head unit the sound
output will be restored.
• If sound output is cut, the gain control of this unit
may be improperly set. To ensure continuous
sound output at increased volume of the head unit,
set the gain control of the amplifier to a proper
position according to the preout maximum output
level of the head unit.
Gain Control of This Unit
There is no need to decrease the volume of the
head unit and too much output is controlled.
Relationship between the gain of the
amplifier and the output power of the
head unit
• If you raise the gain of the amplifier to an improper level, only distortion is increased and the power
increases only slightly.

• If you decrease the volume of the head unit and
set the gain control of the amplifier to the proper
position but still the sound cuts out from time to
time, contact the nearest authorized PIONEER
Service Station.
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.
• The amplifier increases the load on the battery
and charging system. Make sure that the vehicle’s
alternator and battery have sufficient capacity for
this amplifier. The use of a heavy-duty battery,
parallel connection of ordinary batteries or an
energy storage capacitor is recommended.
CAUTION
To prevent damage and/or injury
• Do not ground the speaker wire directly or connect 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 recreational 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.
• DO NOT connect a subwoofer with a lower
impedance than specified in the “Connecting the
Speaker Wires” section. Amplifier damage,
smoke, and overheating could result from a nonspecified connection. The amplifier surface could
also become hot to the touch and minor burns
could result.
• 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.
• Never replace the fuse with one of greater value
or rating than the original fuse. Use of an improper fuse could result in overheating and smoke and
could cause damage to the product and injury
including burns.
• Connect either of three subwoofers to the amplifier; 1: a subwoofer with a 500 W or larger nominal input and an impedance 4 Ω, 2: a subwoofer
with a 1 000 W or larger nominal input and an
impedance 2 Ω or 3: a subwoofer with a 1 200 W
or larger nominal input and an impedance 1 Ω. If
the nominal input and impedance are out of the
above ranges, the subwoofer 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 products may be different colors even if they have the
same function. When connecting this product to
another product, refer to the supplied manuals of
both products and connect cords that have the
same function.

—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-circuit.
• 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.
• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could
become hot to the touch and minor burns could
result.
• 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.
• Never replace the fuse with one of greater value
or rating than the original fuse. Use of an improper fuse could result in overheating and smoke and
could cause damage to the product and injury
including burns.
CAUTION
To prevent malfunction and/or injury
• 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 allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could
become hot to the touch and minor burns could
result.
• 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.
