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 

dealers.

•  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 14 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.

•  BEFORE connecting the speaker leads of the power cord to the speakers, check the speaker wiring in 

your car.
