2CAUTION
This unit is designed to operate on 12 V DC, NEGATIVE ground
electrical systems. JVC recommends consulting a qualified technician
for installation.
• To prevent short circuits while making connections, keep the
battery's negative terminal disconnected.
• This unit uses BTL (Balanced Transformerless) amplifier circuitry,
i.e., floating ground system, so comply with the following:
– Do not connect the "·" terminals of the speakers to each other.
– Do not connect the "·" terminals of the speakers to the metal
body or chassis.
• Cover the unused leads with insulating tape to prevent them from
short circuiting.
• If the fuse blows, first make sure the wires aren't touching to cause
a short circuit then replace the old fuse with one with the same
rating.
• This unit becomes very hot. Be careful not to touch the unit not
only when using but after using. DO NOT disassemble the unit
since there are no user serviceable parts inside.
• To keep the heat dissipation mechanism running effectively, wipe
the accumulated dust off periodically.
• Do not let pebbles, sand or metallic objects get inside the unit.
• Listening to the tape, radio, CD or digital audio player, etc. with
the volume set at a high level for a long period of time will exhaust
the battery, while the engine is turned off or while the engine is
idling.
• Use the speakers which have sufficient capacity to the unit.

The illustration above shows a typical installation. However, you
should make adjustments corresponding to your specific car.
Location of the unit
• Mount this unit on a firm surface, such as in the trunk or under the
front seat.
• When mounting the unit under the front seat, make sure that
adjusting the seat position will not catch any wire of the unit.
• Since heat is generated in the unit, do not mount it near
inflammable objects.
• Do not mount the unit in the places subject to heat: near a
radiator, in a glove compartment or in insulated areas such as
under a car mat that will prevent the unit from dissipating heat.
