If you experience operation or performance problems with this product, compare your
installation with the electrical wiring diagram on the previous pages. If problems persist,
read the following troubleshooting tips which may help eliminate the problems.
The high level input(s) should only be used when your head unit lacks RCA outputs.
If the RCA outputs are not present, connect the speaker outputs from the receiver
to the high level input connector of the amplifier. Be sure to observe polarity to
avoid audio phase problems.
Protection LED
comes on when
amplifier is
powered up.
Check for short circuits on speaker leads.
Turn down the volume control on the head unit to prevent overdriving.
Remove speaker leads, and reset the amplifier. If the Protection LED still
comes on, then the amplifier is faulty and needs servicing.
High hiss in the
speakers.
Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then
plug in the component driving the amplifier and unplug its inputs. If the
hiss disappears at this point, go on until the faulty/noisy component is
found.
It is best to set the amplifier's input level control as low as possible. The
best subjective signal-to-noise ratio is achieved in this manner. Try to set
the head unit as high as possible (without distortion) and the amp input
level as low as possible.
Squealing noise
from speakers.
Check for improperly grounded RCA interconnects.
Distorted sound.
Check that the Input Level Control is set to match the signal level of the
head unit. Always try to set the Input Level as low as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
very hot.
Check that the minimum speaker impedance for the amp model is correct.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add and external cooling fan.
Engine noise
(static type)
This is usually caused by poor quality RCA cables,which can pick up
radiated noise. Use only the best quality cables, and route them away
from power cables.
Engine noise
(alternator
whine)
Check that speaker leads are not shorted to the vehicle chassis.
Check that the RCA grounds are not shorted to the vehicle chassis.
Check that the head unit is properly grounded.

Before installing and using your
new Sound Storm Laboratories
amplifier, please become familiar
with all the information contained
in this manual.
Please keep this manual in a safe
place for future reference.
• Do not open or attempt to repair
this unit yourself. Dangerous high
voltages are present which may result
in electric shock. Refer any repairs to
a qualified service technician.
• To avoid risk of electronic shock or
damage to the amplifier, do not permit
any of this equipment to become
damp or wet from water or drinks. If
this does occur, immediately unplug
the power wires and send the amplifier
to your local dealer or service center
as soon as possible.
• If there is smoke or any peculiar
odor present during use or if there is
damage to any of the component
enclosures, immediately unplug the
power wire and send the amplifier to
your local dealer or service center as
soon as
possible .
7. Insert fuse(s) into the battery fuse
holder(s).
8. Recheck all connections before
powering up the amplifier.
9. Set all lev
el controls to minimum
position, and set all crossover
controls/switches to the desired
frequency points.
10. Power up the head unit and the
amplifier. Then set the volume control
on the head unit to about 3/4 volume,
and adjust the amplifier’s input level
control(s) to just below the level of
distortion.
11. Further fine tuning of the various
controls may be necessary to obtain best
results.
Your FORCE amplifier has been
designed to operate efficiently at loads
down to 2 Ohms. This means that you
can install four 8 Ohm speakers per
channel, when using parallel wiring.
Increasing the number of woofers per
channel at low frequencies (below
100Hz) produces an acoustic coupling
effect. This acoustic coupling effect
increases your power output by about
3dB per speaker, or the equivalent of
an additional 10W per speaker.
When operating at 2 Ohms, the
amplifi
ers will increase their output
power by approximately 50%. The
current draw will also increase by
about the same amount, so be sure
you have enough current to run the
amplifiers into a 2Ohm load.
If you lack adequate current, your
music reproduction will be distorted.
Low-level (RCA) input wiring is preferred for best audio pe
rformance. Always use
a high-quality RCA cable for best audio performance.
