AMPLIFIER FUSE KEEPS BLOWING?
1)
Incorrect
wiring or short circuit: Using your voltmeter, 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.
