This unit is designed to operate 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.

Prepare these before installation....

• To prevent short circuits:
  – Disconnect the battery’s negative terminal and make all electrical connections before installing the unit.
  – Cover the terminals of the UNUSED leads with insulating tape.
• Be sure to ground this unit to the car’s chassis again after installation.
• Replace the fuse with one of the specified rating.
• Connect speakers with a maximum power of more than 50 W 

(impedance of 4 Ω to 8 Ω). Otherwise, change the <AMP GAIN> setting. 
(See above.)

• The heat sink becomes very hot after use. Be careful not to touch it 

when removing this unit.

IMPORTANT: A custom wiring harness (separately purchased) which is suitable for your car is recommended 
for connection between the unit and your car.
• Consult your JVC car audio dealer or a company supplying kits for details.

• 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.
