TROUBLESHOOTING
PROBLEM: No audio and POWER INDICATOR
is
off.
CAUSE and SOLUTION: No voltage at
BATI
+ and/or
REM terminals,
or
bad
or
no ground connection. Check
voltages at amplifier terminals with VOM.
PROBLEM: No audio and PROTECT INDICATOR flashes
every 4 seconds.
CAUSE and SOLUTION: DC voltage on amplifier output.
Amplifier may need service; see enclosed warranty card
for service information.
PROBLEM: No audio and PROTECT and POWER
INDICATORS flash.
CAUSE and SOLUTION: Voltage less than 9V on
BATI
+
connection. Check vehicle charging system.
PROBLEM: No audio and PROTECT INDICATOR
is
on.
CAUSE and SOLUTION: Amplifier
is
overheated. Make
sure amplifier cooling
is
not blocked at mounting location.
Verify that speaker-system impedance
is
within specified
limits.
Or,
there may be voltage greater than 16V (or less
than 8.
5V)
on
BATI
+ connection. Check vehicle charging
system.
PROBLEM: Amplifier fuse keeps blowing.
CAUSE and SOLUTION: The wiring
is
connected
incorrectly or there
is
a short circuit. Review installation
precautions and procedures. Check wiring connections.
PROBLEM: Distorted audio.
CAUSE and SOLUTION: Gain
is
not set properly. Check
INPUT LEVEL setting. Check speaker wires for shorts or
grounds. Amplifier
or
source unit may be defective.
PROBLEM: Distorted audio and PROTECT INDICATOR
flashes.
CAUSE and SOLUTION: Short circuit
in
speaker
or
wire.
Remove speaker leads one at a time
to
locate shorted
speaker or wire, and repair.
PROBLEM: Music lacks dynamics or "punch."
CAUSE and SOLUTION: Speakers are not connected
properly. Check speaker connections for proper polarity.
PROBLEM: Engine
noise-whining
or
clicking-in
system when the engine
is
on.
CAUSE and SOLUTION: Amplifier
is
picking up
alternator noise. Turn down gain. Move audio cables
away from power wires. Install an alternator noise filter on
power line between battery and alternator. Check ground
connections on the
amplifier-
a loose or improper ground
is
one of the main causes for noise.
