minus terminal.
(Not doing so can cause shorts or fires.)
• When extending the ignition, battery, or ground wires, make sure to use
automotive-grade wires or other wires with a 0.75mm^ (AWG18) or more to
prevent wire deterioration and damage to the wire coating.
• To prevent a short circuit, never put or leave any metallic objects (such as
coins or metal tools) inside the speaker.
• Abnormal smell - In the event the unit generates smoke or abnormal smell,
immediately switch the power OFF. After this, please contact your dealer or
nearest service station as soon as possible.
• Modification - Do not attempt to open or modify the unit, for this could
cause fire hazard or malfunction.
• Suffocation - After taking the unit out of the polyethylene bag, be sure to
dispose of the polyethylene bag out of the reach of children. Otherwise, they
may play with the bag, which could cause hazard of suffocation.
FCC WARNING
This equipment may generate or use radio frequency energy. Changes or
modifications to this equipment may cause harmful interference unless the
modifications are expressly approved in the instruction manual. The user could

modification is made.
ACAUTION __
• Do not install the speaker in a spot exposed to direct sunlight or excessive
heat or humidity.
• Water and moisture - Do not install the speakers in locations which may be
subject to water or moisture.
• Dust and unstable locations - Do not install the speakers in unstable
locations or locations subject to dust.
• If the fuse blows, after checking to see if the wiring cord has shorted, be sure
to replace with the stipulated size (amperage) fuse as displayed on the fuse
box.
(Using fuses other than the stipulated size can cause fires.)
To replace the fuse, refer to the vehicle instruction manual.
• To prevent a short circuit when replacing a fuse, disconnect the wiring harness
at first.
• Do not use gasoline, naphtha, or any type of solvent to clean the speaker.
Clean by wiping with a soft, dry cloth.
• Do not connect cables and leads to both RCA cable input jacks and the
speaker input terminals simultaneously, for this may cause malfunction or
damage.
• When making a hole under a seat, inside the trunk, or somewhere else in the
vehicle, check that there is nothing hazardous on the opposite side such as
a gasoline tank, brake pipe; or wiring harness, and be careful not to cause
scratches or other damage.
• For ground wire mounting, do not fasten the wire to an airbag, steering or
brake line system or other critical safety unit bolts or nut.
(Can cause accidents.)
• When mounting, be sure to mount in a place that will not interfere with
driving or be dangerous to passengers during sudden braking etc.
(Cause of injury or accidents.)
• After installing the unit, check to make sure that electrical equipment such as
the brake lamps, turn signal lamps and windshield wipers operate normally.
