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.
•Be sure to ground this unit to the car’s
chassis again after installation.
Notes:
•Replace the fuse with one of the specified
rating. If the fuse blows frequently, consult
your JVC car audio dealer.
•It is recommended to connect to the speakers
with maximum power of more than 50 W (both
at the rear and at the front, with an impedance
of 4 Ω to 8 Ω). If the maximum power is less
than 50 W, change “AMP GAIN” setting to
prevent the speakers from being damaged
(see page 26 of the INSTRUCTIONS).
•To prevent short-circuit, cover the terminals of
the UNUSED leads with insulating tape.
•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.
•BEFORE connecting the speaker leads of the
power cord to the speakers, check the
speaker wiring in your car.
