Bass Boost Control: The variable bass boost control on the side of the CXA360.4 amplifi er is designed to give
you increased output, 0–6dB, at 40Hz. The setting for this control is subjective. If you turn it up, you must readjust
the input gain control to avoid clipping the amplifi er.
Remote Bass-CXARC (not included): With the CXARC remote bass level control, you have the ability to
attenuate the output level of AMP2 remotely (AMP2 must be in LO-PASS X-OVER mode). To surface-mount the
CXARC 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. Connecting the 3.5mm cable without the remote knob will cause the amplifi er to output at full gain, possibly
damaging your speakers.
CXARC REMOTE BASS INSTALLATION
(Optional - CXARC not included.)
Remote cable passes audio; do not
run cable parallel to power wires.
Remote controls AMP2 output.
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 are Power (PWR) &
Protection (PRT) LEDs on the side panel of your Kicker CX series amplifi er. Depending on the state of the amplifi er
and the vehicle's charging system, the LEDs will glow either green or red. When the green LED is lit, this indicates
the amplifi er is turned on and no trouble exists.
Green LED off, no output? With a Volt Ohm Meter (VOM) check the following:
(should read +12V to +16V)
power and ground connections
Green LED on, no output? Check the following:
good speaker.
Substitute source unit with a "known" good source unit.
feeding the amplifi er with the VOM meter set to measure "AC" voltage.
Red LED fl ickering with loud music? The red LED indicates low battery 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.
Red LED on, no output?
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.
down = voltage protection circuitry is engaged. Voltage to the amplifi er is not within the 8–16 volt operating range.
Have the vehicle's charging and electrical system inspected.
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.
No or low output?
Check the balance and fader controls on source unit
and speaker output connections.
Connect the supplied 1/8th inch [3.5mm] patch cable to the
CXARC remote and the Remote Bass jack on the amplifi er
Remote turn-on terminal (should read +12V to +16V)
Ground terminal, for proper conductivity.
Amplifi er is very hot = thermal protection is engaged. Test for proper impedance at
Surface-mount the CXARC remote
using the supplied screws.
