American LEGACY Series amplifiers feature built-in fuse systems. These fuses protect both the
amplifier and the electrical system in your vehicle from tault conditions. If you ever need to
replace the fuse in your American LEGACY Series amp, use a fuse of exactly the same type and
rating. A different type or rating of fuse may result in damage or fire.
notes
troubleshooting
liD autput.
p'rotectlon
clrcultru
The built-in protection circuitry in the American
Legacy Series amplifiers will disable the amplifier
if it senses an input overload, a speaker short circuit,
or extreme temperature conditions.
When the protection circuit is activated by any of
these conditions, the Protection LED will be
illuminated.
If this occurs, carefully inspect the system to
determine the source of the problem.
If the shutdown was a result of a thermal overload
condition, allow the amplifier to cool down before
attempting to restart it.
•
If the shutdown was a result of an input overload,
or speaker short circuit, be sure to correct the
condition before restarting.
•
The amplifier can be restarted by turning the remote
power OFF and then ON again.
Confirm that all terminal strip connections are secure and tight.
Check both in-line and built-in fuses. Both the +12Vand the Remote terminals must have +12V referenced to chassis
ground.
Confirm that the audio signal sourca (car radiO, equalizer, etc.) is connected and is supplying output sig nal. To
check if the amp is supplyinQ sig nal, unrlug the cables from th e signal source (but leave them plugged into the
amp). Bnetly tap the center Pin of each 0 the disconnected RCA plugs with yourlinger. This should produca a noise
(teedback) in your speakers.
Only Dne clulnnel works.
Conlirm that all terminal strip connections are secure and tight.
Check the Balance control on the head unit (or other source) to verify that it is set to its midpoint.
If you are using the Low Level RCA input, reverse the input plugs at the amplifier (i.e., switch the L with the R). If
the channels wh ich is silent switches to the other side, the problem is either in the head uniVother source or the
connecting cables.
Welk autp.t.
Readjust the Input Level Control(s) to better suit the input signal.
IIDIse In tile audlD.
If the noise is a ''whine· whose pitch follows the engine speed, confirm that the amplifier and any other signal
sourcas (head unit, etc.) are properly grounded.
If the noise is a "clicking" or ·popping" noise whose rate follows the engine speed, this usually means that the
vehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service.
Check the rounting of the speaker and input wires to make sure they are not adjacent to wires which interconnect
lights and other accassories.
If the above steps fail to improve or clear noise interterence, the system should be checked by a professional mobile
audio installer.
precautions
Do not operate the amplifier when it is unmounted.
Attach all audio system components securely within
the automobile to prevent damage, especially in an
accident.
Do not mount this amplifier so that the wire
connections are unprotected, or in a pinched
condition, or likely to be darnaged by nearby objects.

Before making or breaking power connections in
your system, disconnect the vehicle battery. Confirm
that your head unit or other equipment is turned off
while connecting the input jacks and speaker
terminals.
If lOU need to replace the power fuse, do so only
With a fuse identical to that supplied with the amplifier.
Using a fuse of a different type or rating may result
in damage that isn1 covered in the manufacturer�
warranty.
