WARNINGS
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 installa\
tion.
Notes:
•   Replace the fuse with one of the specified rating. If the fuse blows fre\
quently, consult your JVC car audio 
dealer.
•   It is recommended to connect speakers with a 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 1\
4 of the INSTRUCTIONS).
•   To prevent short circuits, cover the terminals of the UNUSED leads with \
insulating tape.
•   The heat sink becomes very hot after use. Be careful not to touch it whe\
n removing this unit.

 Connecting the external amplifier / °“√‡™◊ËÕ¡µËÕ‡§√ ◊ËÕߢ¬“¬‡  ’¬ß¿“¬πÕ°
You can connect an amplifier to upgrade your car stereo system. 
•  Connect the remote lead (blue with white stripe) to the remote lead of\
 the other equipment so that it 
can be controlled through this unit.
•  Disconnect the speakers from this unit, connect them to the amplifier. L\
eave the speaker  leads of this unit unused.
*
3  Firmly attach the ground wire to the metallic body or to the chassis of \
the car—to the place uncoated with 
paint (if coated with paint, remove the paint before attaching the wire\
). Failure to do so may cause damage to 
the unit.

WARNINGS
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 speakers with a 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 14 of the INSTRUCTIONS).
•  To prevent short circuits, 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.
