TROUBLESHOOTING GUIDE
This section provides you with a catalog of amplifier symptoms and their probable causes and solu¬
tions. Before you consult this listing, make sure the vehicle's electrical system is working properly by
verifying that other electrical items (e.g. headlights, windows, etc.) still function correctly.
SYMPTOM
PROBABLE CAUSE
SOLUTION
No Audio
Low or No Remote
Turn-On connections
Check remote tum-on voltage at amp
and head unit
Blown Fuse
Replace with new fast-blow fuse
Power wires not
connected
Check butt splices or solder joints;
check Ground and Battery connections
Blown speakers or
not connected
Use VOM or DVM to measure speaker
coil impedance; check speaker wiring
connections
Audio cycles
on and off
Thermal Protection
Circuits are properly
shutting amplifier off
each time it gets too hot
Check location for for adequate
ventilation; check speaker wiring for
a short to chassis
Distorted Audio
Input Sensitivity
not set properly
or damaged speaker
cones
See Calibrating Input Sensitivity
procedure and check each step; inspect
each speaker for damage and repair or
replace suspected component
Low turn-on voltage
Refer to head unit owner's manual
Audio level low
Mute circuit is on
Check electrical system for low voltage;
check ground connection
Audio lacks
Speakers wired with
wrong polarity,
causing cancellation of
bass frequencies
Check polarity of wires from amplifiers
to each speaker as defined by the
system design
External fuse
blowing
Incorrect wiring or
short circuit
Refer to Electrical Installation and check keeps
each installation step
Whining noise on
audio with engine
running
Amplifier is picking
up alternator noise
Install an in-line noise fitter on the head
unit's power wire; check alternator
diodes or voltage regulator for
proper operation
Ticking noise
on audio with
engine running
Amplifier is picking
up radiated spark
noise
Check RCA audio cables routes; install
an in-line noise filter on the head unit's
power wire
