Troubleshooting
Before you contact your FUSION dealer or service center, you
should perform a few simple troubleshooting steps to help
diagnose the problem.
If the FUSION amplifier has been installed by a professional
installation company, you should contact the company so a
technician can assess the problem and advise you about
possible solutions.
There is no sound, and the POWER LEDs are off
• Check the amplifier turn-on wire connection to the stereo or
switch, and tighten or re-connect all wires, if needed
(Connecting to Power, page 2).
NOTE: The amplifier and the stereo must connect to a
common ground for the amplifier turn-on signal to function
properly.
• Check the fuse or circuit breaker on the power cable (near
the battery), and replace the fuse or reset the breaker, if
needed.
• Check the fuses on the amplifier, and replace all blown fuses,
if needed.
• Check the power and ground cable connections, and tighten
or re-connect all cables, if needed.
• Make sure you are using the appropriate gauge for the length
of the power cable run, and replace the cable with a thicker
gauge, if needed (Power Cable Gauge Guide, page 2).
There is no sound, and the POWER LEDs are on
• Check the settings on the stereo, and make sure the
appropriate zone out or subwoofer out signals are enabled.
NOTE: See your stereo owner's manual for more information
on enabling or configuring output signals.
• Make sure the stereo is powered on and the volume is not
set too low.
• Check the RCA cable connections to the stereo, and re-
connect all disconnected cables, if needed.
• Check the LEVEL setting for the zone on the amplifier and
the max volume setting for the zone on the stereo, and
increase the LEVEL on the amplifier or the max volume on
the stereo, if needed (Adjusting the Level for a Zone, page 4).
• Check the speaker wire connections, and re-connect all
disconnected wires, if needed.
• Check the power cables to make sure they are the
appropriate gauge, are fused, and are connected properly
(Connecting to Power, page 2).
One POWER LED is on, but the other POWER LED is off
• Check the fuses on the side of the amplifier where the
POWER LED is off, and replace all blown fuses.
The PROT LEDs are on
The PROT LEDs indicate a fault in the system. When a fault is
detected, the amplifier shuts down to prevent damage.
• Check the power and ground cables for cuts in the sleeving
or bare wire contact, and correct, repair, or replace the
cables if necessary.
