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
distortion.
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
boat; the use of headphones may create a
traffic hazard and is illegal in many areas.

WARNING
To prevent fire hazard, the heatsink should never
be covered (such as by paper, material, etc.).
This unit is for boats with a 12 V battery and
negative grounding. Before installing, check
the battery voltage.
When installing this unit, make sure to con-
nect the ground wire first. Ensure that the
ground wire is properly connected to the neg-
ative ground circuit of the boat. Use adequate
gauge, marine grade electrical wire that has
been properly terminated for marine use to
make a direct connection to the negative bus
bar or negative ground distribution system.
Do not attempt to ground the amplifier using
the mounting screws.
Use fused marine grade battery wire (sold
separately) of adequate gauge that has been
properly terminated for marine use to make
a direct connection to the positive bus bar or
positive distribution system.
If the screw for the ground wire loos-

Always use a fuse of the rating prescribed.
The use of an improper fuse could result in
overheating and smoke, damage to the prod-
uct, and injury, including burns.
Check all electrical and signal connections
(power, ground, amplifier, speaker, etc.) if
amplifier fuse or battery wire fuse blows.
Resolve any loose or short circuited connec-
tions, then replace the blown fuse with an
identical value equivalent.
Always install the amplifier on an even sur-
face. Do not install the amplifier on a surface
that is uneven or has 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 boat. Doing so
could cause malfunction.
In the event of any abnormality, the power
supply to the amplifier may cut off to pre-
vent equipment malfunction. If this occurs,
switch the system power off and check all
electrical and signal connections (power,
ground, amplifier, speaker, etc.) for loose or
short circuited connections. If you are unable
to determine the cause, please contact your
dealer.
Always disconnect the negative
terminal
of the battery before making any electrical or
signal connections to avoid the risk of electric
shock or short circuit during installation.
Do not attempt to disassemble or modify
this unit. Doing so may result in fire, electric
shock or other malfunction. Damage or
defects resulting from alterations or modifica-
tions not authorized in writing by Pioneer are
excluded from limited warranty coverage.
Do not install the amplifier in a location
exposed to direct sunlight or excessive heat,
humidity or dust.
