ELECTRICAL CONNECTIONS
To prevent short circuits, we recommend that
you disconnect the battery’s negative terminal
and make all electrical connections before
installing the unit. If you are not sure how to
install this unit correctly, have it installed by a
qualified technician.
Note:
This unit is designed to operate only on 12 V
DC, NEGATIVE ground electrical systems. If
your vehicle does not have this system, a
voltage inverter is required, which can be
purchased at JVC car audio dealers.
• Replace the fuse with one of the specified
rating. If the fuse blows frequently, consult
your JVC car audio dealer.
• If noise is a problem...
This unit incorporates a noise filter in the
power circuit. However, with some vehicles,
clicking or other unwanted noise may occur. If
this happens, connect the unit’s rear ground
terminal (see connection diagram) to the car’s
chassis using shorter and thicker cords, such
as copper braiding or gauge wire. If noise still
persists, consult your JVC car audio dealer.
• Maximum input of the speakers should be
more than 50 W at the rear and 50 W at the
front, with an impedance of 4
Ω to 8 Ω.
• Be sure to ground this unit to the car’s
chassis.
• The heat sink becomes very hot after use. Be
careful not to touch it when removing this unit.

PRECAUTIONS on power supply and
speaker connections:
• DO NOT connect the speaker leads of the
power cord to the car battery; otherwise,
the unit will be seriously damaged.
• Connect the black lead (ground), yellow lead
(to car battery, constant 12 V), and red lead
(to an accessory terminal) correctly.
• BEFORE connecting the speaker leads of the
power cord to the speakers, check the
speaker wiring in your car.
– If the speaker wiring in your car is as
illustrated in Fig. 1 and Fig. 2 below, DO
NOT connect the unit using that original
speaker wiring. If you do, the unit will be
seriously damaged.
Redo the speaker wiring so that you can
connect the unit to the speakers as
illustrated in Fig. 3.
– If the speaker wiring in your car is as
illustrated in Fig. 3, you can connect the unit
using the original speaker wiring in your car.
– If you are not sure of the speaker wiring of
your car, consult your car dealer.

About sounds reproduced through
the rear terminals
• Through the analog terminals (Speaker
out/LINE OUT/2nd AUDIOOUT):
2-channel signal is emitted.
When playing a multi-channel encoded disc,
multi-channel signals are downmixed.
(AUDIO—ANALOG DOWN MIX: see page
46 of the Instructions)
• Through DIGITAL OUT (optical):
Digital signals (Linear PCM, Dolby Digital*,
DTS**, MPEG Multichannel) are emitted
through this terminal. (For more details, see
page 71 of the Instructions.)
To reproduce multi-channel sounds such as
Dolby Digital and DTS, connect an amplifier
or a decoder compatible with these multi-
channel sources to this terminal, and set
“DIGITAL AUDIO OUTPUT” to the correct
value. (See page 46 of the Instructions)
