TROUBLESHOOTING
For more details, consult your “JVC IN-CAR ENTERTAINMENT” car audio dealer.
The POWER/PROTECTOR lamp does not light.
• Confi rm if the fuse is blown.
• Confi rm if the ground lead is connected securely to a metal part of the car.
• Make sure that the equipment connected to this unit is turned on.
• Use a relay if your system employs too many amplifi ers.
• Confi rm the battery voltage (11 V to 16 V).
The POWER/PROTECTOR lamp lights in red and/or the unit heats up abnormally.
• Confi rm if the impedance of the connected speaker is suitable.
• Confi rm if the speaker wirings are short-circuited.
• Leave the unit turned off for a while as it cools down.
No sound is heard.
• Confi rm if the POWER/PROTECTOR lamp lights in green (see “POWER SUPPLY” on page 1).
• Is the remote turn-on line lead connected correctly?
• Are RCA pin cords connected to the LOW INPUT jacks?
• Is the speaker input connector from the receiver connected to the HIGH INPUT terminal?
• Is this amplifi er grounded?
Alternator noise is heard.
• Keep the power connecting leads away from the RCA pin cords.
• Keep the RCA pin cords away from other electrical cables in the car.
• Confi rm if the ground lead is connected securely to a metal part of the car.
• Confi rm if the negative speaker leads are touching the car chassis.
• Confi rm if the noise originates in the receiver.
• Replace the plugs or use plugs with load resistors.
• Connect a bypass capacitor across the accessory switches (horn, fan, etc.).
Noise when connected to AM (MW/LW) tuner.
• Move the speaker and power leads away from the antenna (aerial) lead.
• Depending on the manufacturer and model of the car, speaker wiring may have been fi nished
when purchased. If the ground wire is common to both left and right speakers, this unit cannot
be used. In this case, redo the speaker wiring.
å When your receiver is equipped with Line Output, connect the Line Output (through the
receiver) to the LOW INPUT jacks on this unit.
∫ When your receiver is NOT equipped with Line Output, connect the speaker connector
(through the receiver) to the HIGH INPUT terminal on this unit.

SPEAKER CONNECTIONS
Connection varies depending on the number of the speakers used in your car. Select the
appropiate connection referring to the diagrams below.
Before connecting: Securely connect all the parts. If the connections are loose, due to contact
resistance etc., heat will break out and may cause an accident. Secure and cover the cords with
insulating tape and run them under the car mats.
