Before you start

The Safety of Your Ears is in
Your Hands
Get the most out of your equipment by playing
it at a safe level—a level that lets the sound
come through clearly without annoying blar-
ing or distortion and, most importantly, with-
out affecting your sensitive hearing. Sound
can be deceiving. Over time, your hearing
“comfort level”adapts to higher volumes of
sound, so what sounds “normal”can actually
be loud and harmful to your hearing. Guard
against this by setting your equipment at a
safe level BEFORE your hearing adapts.
ESTABLISH A SAFE LEVEL:
!Set your volume control at a low setting.
!Slowly increase the sound until you can
hear it comfortably and clearly, without dis-
tortion.
!Once you have established a comfortable
sound level, set the dial and leave it there.
BE SURE TO OBSERVE THE FOLLOWING
GUIDELINES:
!Do not turn up the volume so high that you
can’t hear what’s around you.
!Use caution or temporarily discontinue use
in potentially hazardous situations.
!Do not use headphones while operating a
motorized vehicle; the use of headphones
may create a traffic hazard and is illegal in
many areas.

cer and birth defect or other reproductive
harm. Wash hands after handling.
!This unit is for vehicles with a 12 V battery and
negative grounding. Before installing in re-
creational vehicles, trucks or buses, check the
battery voltage.
!Always use a fuse of the rating prescribed.
The use of an improper fuse could result in
overheating and smoke, damage to the pro-
duct and injury, including burns.
!Check the connections of the power supply
and speakers if the fuse of the separately sold
battery wire or the amplifier fuse blows. Deter-
mine and resolve the cause, then replace the
fuse with and identical equivalent.
!Do not allow this unit to come into contact
with liquids. Electrical shock could result.
Also, damage to this unit, smoke, and over-
heating 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 un-
able to determine the cause, please contact
your dealer.
Before you start

!Always disconnect the negative *terminal of
the battery beforehand to avoid the risk of
electric shock or short circuit during installa-
tion.

1GAIN (gain) control
If output remains low, even when the car
stereo volume is turned up, turn controls to
lower level. If distortion occurs when the car
stereo volume is turned up, turn these con-
trols to higher level.
!For use with an RCA equipped car stereo
(standard output of 500 mV), set to the
NORMAL position. For use with an RCA
equipped Pioneer car stereo, with maxi-
mum output of 4 V or more, adjust level
to match that of the car stereo output.
!If you hear too much noise when using
the speaker input terminals, turn the
gain control to higher level.
!If using only one input plug, set the gain
controls for speaker outputs A and B to
the same position.

Setting the unit

Setting gain properly
!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.
!A cut in sound output may indicate impro-
per setting of the gain control. To ensure
continuous sound output with the head
unit at a high volume, set amplifier gain
control to a level appropriate for the preout
maximum output level of the head unit, so
that volume can remain unchanged and to
control excess output.
!Despite correct volume and gain settings,
the unit sound still cuts out periodically. In
such cases, please contact the nearest
authorized Pioneer Service Station.
Gain control of this unit
Preout level: 2 V
(Standard: 500 mV)
Above illustration shows NORMAL gain set-
ting.
Relationship between amplifier gain
and head unit output power
If amplifier gain is raised improperly, this will
simply increase distortion, with little increase
in power.

Before installing the amplifier
WARNING
!To ensure proper installation, use the supplied
parts in the manner specified. If any parts
other than those supplied are used, they may
damage internal parts of the amplifier, or be-
come loose causing the amplifier to shut
down.
!Do not install in:
—Places where it could injure the driver or
passengers if the vehicle stops suddenly.
—Places where it may interfere with the dri-
ver, such as on the floor in front of the dri-
ver’s seat.
!Install tapping screws in such a way that the
screw tip does not touch any wire. This is im-
portant to prevent wires from being cut by vi-
bration of the car, which can result in fire.
!Make sure that wires do not get caught in the
sliding mechanism of the seats or touch the
legs of a person in the vehicle as short-circuit
may result.
!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 ampli-
fier, 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.
!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 be-
tween the amplifier and the automobile.
Doing so could cause malfunction.
!Protection function may activate to protect the
amplifier against overheating due to installa-
tion in locations where sufficient heat cannot
be dissipated, continuous use under high-vo-
lume conditions, etc. In such cases, the am-
plifier shuts down until it has cooled to a
certain designated temperature.
!The optimal installation location differs de-
pending on the car model. Secure the ampli-
fier at a sufficiently rigid location.
!Firstly make temporary connections and
check to ensure the amplifier and system op-
erate properly.
!After installing the amplifier, confirm that the
spare tire, jack and tools can be easily re-
moved.
!Make sure to hold the middle part of the unit
when carrying. If the terminal cover is held to
lift the unit, the cover may come off and cause
the unit to fall, and result in injury.
