Troubleshooting

If your amplifier does not appear to be working, check obvi- ous things first such as blown fuses, poor or incorrect wiring connections, crossovers set improperly, gain controls improperly set, etc.

There are two LEDs on the end panel of your KICKER SX series amplifier, one green and one red. The green LED indi- cates the amplifier is turned on. The red LED indicates that there is a fault condition with the end panel fuses and they need checked.

The power indicator on top of the amplifier which illumi- nates 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 turn-on terminal (should read +12V to +16V). ¬Ground terminal to chassis ground (should read 0).

Green LED on, no output:

¬Check amp status in SICK BAY.

¬Check GAIN RANGE in SYSTEM menu. ¬Check GAIN LEVEL in GAIN menu. ¬Check if MUTE is activated.

¬Test amp using PINK NOISE in SICK BAY menu. ;If amp makes noise using PINK NOISE then: ¬Check RCA cable and connections.

¬Check for signal on RCA cable with VOM in AC position.

¬Substitute known good source unit.

;If amp does not make noise using PINK NOISE then: ¬Check speaker connections.

¬Test speaker outputs with known good speaker.

Other Symptoms:

;Amp is very hot, no output.

¬Thermal protection is engaged. Check SICK BAY to verify. Check for proper impedance at speaker terminals. Also check for adequate airflow around amplifier.

;Amp shuts down while vehicle is running.

¬Over Voltage protection engaged. Check SICK BAY to verify. Voltage to the amplifier is not within the 9-16 volt operating range. Have automobile charging/electrical system inspected.

;Amp only plays at low volume levels.

¬Short circuit protection engaged. Check SICK BAY to verify. Check for speaker wires shorted to each other or the vehicle chassis. Damaged speakers or operating amplifier below minimum recommended impedance will also cause this.

;Weak bass output.

¬Change the phase of the LEFT channel in the PHASE menu. If bass improves then one speaker channel is out of phase (polarity). You can leave PHASE changed for this channel to fix the problem or better yet; Check speaker connections to amp and speakers to determine which one is wrong and correct. Be sure to set the PHASE of the LEFT channel back to original setting after correcting wiring connections.

Alternator noise (whining sound that varies with engine RPM):

¬Check for damaged RCA cables. ¬Check routing of RCA cable. ¬Check source unit for good ground.

¬Check GAIN RANGE in SYSTEM menu, turn down if set too high.

¬Check GAIN in MAIN MENU, turn down if set too high.

CAUTION: When jump-starting the vehicle, be sure that connections made with jumper cables are cor- rect. Improper connections (+ to - & - to +) will result in blown amplifier fuses as well as failure to other systems in the vehicle.
