Adjustable Subsonic Filter (SUB): The variable subsonic fi lter will provide a cut-off point for lower frequencies
(10–80Hz) that could potentially damage your speakers from over-excursion, along with wasting your amplifi er's
power. The setting for this control should be set relative to your speaker's low-frequency capability.
Remote Bass-KXRC: With the KXRC remote bass level control, you have the ability to control the output level
of the amplifi er remotely. To surface-mount the KXRC remote bass level control, simply screw the remote to the
chosen location, then run the cable from the controller to the "Remote Bass" jack on the amplifi er panel. Do NOT
connect/disconnect while the amplifi er is on. See page 6.
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 switch and gain controls, etc. There is a Protection
(PRT) LED on the side panel of your KICKER KXM series amplifi er. Depending on the state of the amplifi er and
the vehicle's charging system, the LED will either glow red or be off.
Red (PRT) LED fl ickering with loud music? The red (PRT) LED indicates low battery voltage or an illegal
load. 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.
Red (PRT) LED on, no output?
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow around
the amplifi er.
Amplifi er shuts down only while vehicle is running = 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.
Amplifi er will only play at low volume levels = short circuit protection is engaged. Check
for speaker wires shorted to each other or to the vehicle chassis. Check for damaged speakers or speaker(s)
operating below the minimum recommended impedance.

Check the routing of RCA (or speaker input) cable
the gain settings and turn them down if they are set too high.
Ground Noise? On a boat or other watercraft, alternator noise or ground loop noise is usually a voltage potential
difference, and it can happen on either the positive or the ground side of the power wiring. The most common
issue is that the stereo system wiring is delivered from two different locations and is therefore at two different
voltage potentials. The head unit power usually comes from the helm's wiring harness, while the amplifi er's power
comes straight from the battery. The helm wiring has lots of noise on it from tachometers (the most common
engine noise culprit), depth fi nders, and engine management computers. The helm ground cable is often too
small for its total load. As a result, both the positive and the ground are usually at different voltage potentials
compared to amplifi er power wiring.
The easiest way to get rid of noise is to ensure that the head unit's positive and ground wire are at exactly the
same voltage potential as the amplifi er(s). The easiest way to accomplish this is to have the head unit's power
wiring removed from the helm's power harness, moving it directly to the battery or the amplifi er's power terminals,
with the positive wire running through a switch or switched relay to allow the system to be turned on or off.
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.
