TROUBLESHOOTING
The POWER indicator does not light.
• Change the fuses if the current one is blown.
• Connect the ground lead securely to a metal part of the car.
• Confirm the battery voltage (11 V to 16 V).
• Leave the unit turned off to cool it down if it heats up abnormally.
No sound is heard.
• Confirm the connections for the power supply. (See “POWER
SUPPLY CONNECTION”.)
• Connect the RCA pin cords to the INPUT jacks, or the speaker input
connector to the HIGH INPUT terminal.
• Confirm the speaker wirings and the position of the CROSSOVER
filter switch. (See “SPEAKER CONNECTIONS”.)
Alternator noise is heard.
• Keep the leads of the POWER terminals away from the RCA pin
cords.
• Keep the RCA pin cords away from other electrical cables in the
car.
• Connect the ground lead securely to a metal part of the car.
• Make sure the speaker negative leads do not touch the car chassis.
• Connect a bypass capacitor across the accessory switches (horn,
fan, etc.).
