AMPLIFIER FUSE KEEPS BLOWING?
1)
Incorrect
wiring or short circuit: Using your DMM, make sure
that all voltage polarities are correct, Review section
(Installation) for proper wire connection.
2)
Amplifier
being driven too hard: Turn down the volume. Gain or
Bass Boost not properly set, Review section (Tuning)
for setting the Gain and Bass Boost properly.
3)
Under-sized or faulty fuse installed: Replace the fuse
with a fuse of the same rating in accordance with the
manufacturer’s suggestion.
WHINING NOISE WHEN ENGINE IS ON?
1)
RCA
cables too close to power wire: Separate RCA and
power cables, Run an extra set of RCAs on the
outside of the vehicle, and if noise is eliminated you
might need a better shielded RCA cable.
2)
Ground
loop problem: Re-Ground the amplifier to a more
electrically conductive location, Re-Ground the stereo
head unit to a more electrically conductive location,
Re-ground the amplifier to a point of the vehicle that
is secure and not thin metal, Make sure that bare
metal is in contact with the connector.
3)
Induced
noise: Relocate components away from electrical
noise sources such as engine control computers and
ABS brake control modules.
AMPLIFIER SHUTS DOWN AFTER PLAYING FOR
A PERIOD OF TIME? 1)
Thermal protection circuits
are shutting the amplifier off: Check the location for
adequate ventilation (Relocate amplifier if necessary),
Impedance may be too low and over heating the
amplifier.
