Trouble shooting
If your amplifier does not appear to be working, check obvious things first such as blown fuses, poor or incorrect wiring connections, gain controls properly set, etc.
There are two LEDs on the end panel of your Kicker KX series amplifier, one green and one red. When the green LED is lit this indicates the amplifier is turned on and no trouble exists. If the green LED turns off and the red LED is lit this indicates that the protection circuitry (SORT) is engaged.
The power indicator on top of the amplifier which illuminates the model badge follows the same function as the green LED.
Green LED off, no output:
With a Volt Ohm Meter (VOM) check:
+12 volt power terminal (should read +12V to 16V). Remote
Green LED on, no output:
Check RCA connections.
Test speaker outputs with known good speaker. Substitute known good source unit.
Check for signal on RCA cable with VOM meter in AC position.
Red LED on, no output:
1.) Amp is very hot.
Thermal protection is engaged. Check for proper impedance at speaker terminals. Also check for adequate airflow around amplifier.
