TROUBLESHOOTING
If your amplifi er does not appear to be working, check the obvious things fi rst such as blown fuses, poor or
incorrect wiring connections, incorrect setting of crossover and gain controls, etc. There is a dual-stage PWR/
PRT LED on side panel of your powered enclosure denoting the power state of the amplifi er. When the LED is
blue, this indicates the powered enclosure is turned on and its amplifi er is functioning properly.
PWR/PRT LED off, no output? With a Volt Ohm Meter (VOM) check the following:
(should read +12V to +16V)
power and ground connections.
Check the AUTO TURN-ON switch setting. Check for a DC offset between a speaker lead and ground if using
DC-OFFSET mode.
PWR/PRT LED blue (Amp not in protection), no or low output? Check the following:
connections
Check the balance control on source unit
Check for a signal in the audio cable feeding the powered enclosure with the VOM meter set to measure
"AC" voltage.
Substitute source unit with a "known" good source unit.
PWR/PRT LED red (Amp in protection), no output?
voltage protection circuitry is engaged. Voltage to the amplifi er is not within the 10–16 volt operating range. Have
the vehicle's charging and electrical system inspected.
voltage. Check all the connections in your vehicle's charging system. It may be necessary to replace or charge
your vehicle's battery or replace your vehicle's alternator.
Reduced bass response? Flip the phase switch to the opposite position; if the bass improves, your speakers
were out of phase with the subwoofer.
Ground Noise? KICKER amplifi ers are engineered to be fully compatible with all manufacturers' head units.
Some head units may require additional grounding to prevent noise from entering the audio signal. If you are
experiencing this problem with your head unit, in most cases running a ground wire from the RCA outputs on the
head unit to the chassis will remedy this issue. If you still have problems, run your input signal at speaker-level
from your source unit to the amplifi er.
CAUTION: When jump starting the vehicle, be sure that connections made with jumper cables are correct.
Improper connections can result in blown amplifi er fuses as well as the failure of other critical systems in the
vehicle.
