!
the car battery positive terminal + and the
ground wire to the car body.
This unit is for vehicles with a 12 V battery and
negative grounding. Before installing in recreational vehicles, trucks or buses, check the
battery voltage.
When installing this unit, make sure to connect the ground wire first. Ensure that the
ground wire is properly connected to metal
parts of the car’s body. The ground wire of the
one of this unit must be connected to the car
separately with different screws. If the screw
for the ground wire loosens or falls out, it
could result in fire, generation of smoke or
malfunction.
Use a fuse of the rating prescribed.
Check the connections of the power supply
and speakers if the fuse of the separately sold
battery wire or the amplifier fuse blows. Determine and resolve the cause, then replace the
fuse with and identical equivalent.
Always install the amplifier on a flat surface.
Do not install the amplifier on a surface that
is not flat or on a surface with a protrusion.
Doing so could result in malfunction.
When installing the amplifier, do not allow
parts such as extra screws to get caught between the amplifier and the automobile.
Doing so could cause malfunction.
Do not allow this unit to come into contact
with liquids. Electrical shock could result.
Also, damage to this unit, smoke, and overheating could result from contact with liquids.
The surfaces of the amplifier and any attached
speakers may also heat up and cause minor
burns.
In the event of any abnormality, the power
supply to the amplifier is cut off to prevent
equipment malfunction. If this occurs, switch
the system power off and check the power
supply and speaker connections. If you are unable to determine the cause, please contact
your dealer.
Disconnect the negative terminal of the battery before installation.

To increase the level, turn LEVEL ADJUST
(level adjustment) clockwise. To decrease
the level, turn LEVEL ADJUST (level adjustment) counterclockwise.
! In case of a bridge connection of speakers, set the speakers’ LEVEL ADJUST
(level adjustment) switches to the same
position.
Setting the Unit
! When connecting to a car stereo that
outputs high power, if you turn up the volume of the car stereo and distortion is
increased, turn down the car stereo volume.
What’s what
4 SUPER HI-VOLTAGE MODE (super highvoltage mode) switch
When connecting to RS-P99 (sold separately), turn on the
SUPER HI-VOLTAGE MODE (super high-voltage mode) switch.
! Set the LEFT CHANNEL (left channel)
and RIGHT CHANNEL (right channel)
switches to the same position.
! When connecting to devices other than
RS-P99, turn the switch to off. If you turn
it on, the volume may decrease.
Setting level adjustment
control appropriately
! Protective function included to prevent
malfunction of the unit and/or speakers
due to excessive output, improper use or
improper connection.
! When outputting high volume sound etc.,
this function cuts off the output for a few
seconds as a normal function, but output
is restored when the volume of the head
unit is turned down.
En

Section
02
Setting the Unit
! A cut in sound output may indicate that the
output level of the head unit and the input
level of the amplifier do not match. To ensure continuous sound output with the
head unit at a high volume, turn the amplifier level adjustment control right or left to
a level appropriate for the preout maximum
output level of the head unit to control excess output.
! Despite correct volume and level adjustment control settings, the unit sound still
cuts out periodically. In such a case, please
contact the nearest authorized Pioneer Service Station.
Level adjustment control of this unit
! If the amplifier level adjustment control is
raised inappropriately, this will simply increase distortion, with little increase in
power.
! If the signal waveform is distorted by high
output, raising the level adjustment control
of the amplifier only changes the power
slightly.

! If the system remote control wire of the amplifier is connected to the power terminal via the
ignition switch (12 V DC), the amplifier will remain on with the ignition whether the car
stereo is on or off, which may exhaust battery
if the engine is at rest or idling.
! Install and route the separately sold battery
wire as far 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.
About bridged mode
Note
INPUT SELECT (input select) switch must be set.
For details, see Setting the Unit on page 5.
Before connecting the
amplifier
WARNING
! Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap sections
in contact with metal parts in adhesive tape.
! Never cut the insulation of the power supply
to feed power to other equipment. Current capacity of the wire is limited.
CAUTION
! Never shorten any wires, the protection circuit
may malfunction.
! Never wire the speaker negative cable directlyto ground.
! Never band together multiple speaker’snegative cables.

En
Speaker impedance is max. 4 W, please carefully
check. Improper connection to the amplifier may
result in malfunction or personal injury due to
burns from overheating.
For bridged mode for a two-channel amplifier,
with a 4 W load, either wire two 8 W speakers in
parallel, Left + and Right * (Diagram A) or use a
single 4 W speaker. For other amplifiers, please
follow the speaker output connection diagram for
bridging shown on rear: two 8 W speakers in parallel for a 4 W load or a single 4 W speaker per
channel.
For any further enquiries, contact your local
authorized Pioneer dealer or customer service.

Connecting the power
terminal
WARNING
Solderless terminal
connections
! Do not connect cords with exposed core
wires to the amplifier power terminals
(power terminal, ground terminal, system
remote control terminal), since disconnection or breakage may result in fire or shortcircuit.
! Periodically inspect and tighten the wire as
necessary.
! Do not solder or bind the ends of the
twisted wires.
! Fasten while ensuring the insulating
sheath of the wire is not clamped.
! Use the supplied hexagonal wrench to
tighten and loosen the terminal screw of
the amplifier and use it to securely fasten
the wire. Be careful to avoid excessive tightening of this screw, which may damage
the wire.
CAUTION
Use the supplied hexagonal wrench to tighten
the screws when fastening wires to the terminal.
The use of a long, commercially available hexagonal wrench may exert excessive torque, possibly
resulting in damage to the terminals and
wires.
! The use of a special red battery and ground
wire RD-228, available separately, is recommended. Connect the battery wire directly to
the car battery positive terminal (+) and the
ground wire to the car body.
! If the battery wire is not securely fixed to the
terminal using the terminal screws, there is a
risk of overheating, malfunction and injury, including minor burns.

Installation
Before installing the amplifier
WARNING
Example of installation on
the floor mat or chassis
1 Place the amplifier in the desired installation location.
Insert the supplied tapping screws (5 mm ×
25 mm) into the screw holes and push on the
screws with a screwdriver so they make an imprint where the installation holes are to be located.

Installation
! Do not use unauthorized parts as this may
cause malfunctions.
! Do not install this unit where:
— it may interfere with operation of the vehicle.
— it may cause injury to a passenger as a result of a sudden stop.
! 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.
! Place all cables away from moving parts, such
as the gear shift and seat rails.
! When drilling to install the amplifier, always
confirm no parts are behind the panel and
protect all cables and important equipment (e.
g. fuel/brake lines, wiring) from damage.

CAUTION
! To ensure proper heat dissipation of the amplifier, ensure the following during installation:
— Allow adequate space above the amplifier
for proper ventilation.
— Do not cover the amplifier with a floor mat
or carpet.
! Place all cables away from hot places, such
as near the heater outlet.
! The optimal installation location differs depending on the car model. Secure the amplifier at a sufficiently rigid location.
! Check all connections and systems before
final installation.
! After installing the amplifier, confirm that the
spare tire, jack and tools can be easily removed.
