Features
About 2 Ohm operation
Your new CHAOS EXXTREME amplifier
features the following:
Your CHAOS EXXTREME 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.
• Class A-B operation
• Bridgeable outputs
(except CX1100M and CX2000M)
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.
• Tri-Mode capable
(except CX1100M and CX2000M)
• MOSFET PWM (Pulse Width
Modulated) Power Supply
• 2 Ohm stable stereo operation
with output power increase
When operating at 2 Ohms, the
amplifiers 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 2 Ohm load.
• Thermal and speaker short
protection
• Soft turn-on circuit
• Remote turn-on/turn-off circuit
• Variable input gain control
• Variable low pass crossover(s)
• Fixed high pass crossover(s)
• Variable 0 to +18dB Bass Boost
If you lack adequate current, your
music reproduction will be distorted.
• Nickel-plated RCA low level and
high level inputs
• LED power and protection
indicators
• Silver anodized heatsink
• Remote subwoofer level control

General precautions
Before installing and using your
Before making or breaking power
connections in your system,
new
amplifier, please be-
come familiar with all the infor-
mation contained in this manual.
disconnect the vehicle battery. Confirm
that your head unit or other equipment
is turned off while connecting the input
jacks and speaker terminals.
Please keep this manual in a safe
place for future reference.
If you need to replace the power fuse,
replace it only with a fuse identical to
that supplied with the amplifier. Using
a fuse of a different type or rating may
result in damage to your audio system
or your amplifier which is not covered
by the manufacturer's warranty.
• 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.
Mounting the amplifier
1. Find a suitable location in the vehicle
in which to mount the amplifier.
2. Make sure there is sufficient air
circulation around the intended
mounting location.
• 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 .
3. Mark the location for the mounting
hole screws by positioning the amplifier
where you wish to install it. Use a
scribe or mounting screw, inserted
through each of the amp's mounting
holes, to mark the mounting surface.
If the mounting surface is carpeted,
measure the hole centers and mark
with a felt tip pen.
Installation precautions
4. Drill pilot holes in the mounting
surface for the mounting screws. Place
the amplifier in position, and attach
the amplifier to the mounting surface
securely using screws.
Before you drill or cut any holes,
investigate your car's layout very
carefully. Take special care when you
work near the gas tank, fuel lines,
hydraulic lines and electrical wiring.
Never operate the amplifier when it is
unmounted. Attach all audio system
components securely to prevent
damage, especially in an accident.
SHOCK HAZARD! Do not open the case
of this product. There are dangerous
voltages present within the unit. There are
no user-serviceable parts within the unit.
CHAOS EXXTREME MOSFET Amplifier User’s Manual - page 4
Connecting the amplifier
Before doing any wiring, look through
this manual and identify the diagrams
to follow for power, input and speaker
connections for your particular
installation. Be sure you understand
all the connections before you proceed.
7. Insert fuse(s) into the battery fuse
holder(s).
8. Recheck all connections before
powering up the amplifier.
9. Set all level controls to minimum
position, and set all crossover
controls/switches to the desired
frequency points.
1. Connect the power ground terminal
to the closest point on the chassis of
the car. Keep this ground wire to less
than 39" (100 cm) in length. Use 8
gauge (or heavier) wire.
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.
2. Connect the remote terminal to the
remote output of the head unit using
16 gauge (or heavier) wire.
3. Connect an empty fuse holder within
18" (45 cm) of the car battery, and run
8 gauge (or heavier) cable from this
fuse to the amplifier location.
11. Further fine tuning of the various
controls may be necessary to obtain best
results.
4. Check that the fuse holder is empty.
Then connect the fuse holder to the
"BATT+" connection on the amplifier.
Don't misuse the
level control!
5. If multiple amplifiers are being used
in your system, either:
Do not mistake the input level control
for a volume control! It is designed
ONLY to match the output level of
your audio source to the input level
of your amplifier.
• Run a separate pair of cables from
the battery and a chassis ground point
to each amplifier. Each (+) cable must
have its own inline fuse.
-or-
Do not adjust this input level to
maximum unless your input level
requires it.
• Run a #4 cable from the fuse holder
at the battery to a distribution block
at or near the amplifier's location. Then
run separate cables from the amplifier
to this distribution block and to
Ignoring these instructions will result
in an input overload to the amplifier,
and excessive audio distortion. It
can also cause the protection circuit
to engage.
independent chassis ground points.
6. Connect all line inputs and outputs
(if used) using high-quality cables.
Connect all speakers, following the
diagrams in this manual. Be sure to
observe proper polarity to avoid audio
phase problems.
CHAOS EXXTREME MOSFET Amplifier User’s Manual - page 5
Low Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Always use
a high-quality RCA cable for best audio performance.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!

Troubleshooting
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.
SYMPTOM
POSSIBLE REMEDY
Check to make sure you have a good ground connection.
Check that the Remote Input (Turn-On) has at least 3VDC.
Check that there is battery power on the (+) terminal.
Check that there is at least 12v.
Amplifier will not
power up.
Check all fuses, replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit, shut off
the amplifier briefly, and then repower it.
Check for short circuits on speaker leads.
Protection LED
comes on when
amplifier is
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.
powered up.
Check that all fuses are OK.
No output.
Check that amplifier is properly grounded.
Check that the Remote Input (Turn-On) has at least 3VDC.
Check that the RCA audio cables are plugged into the proper inputs.
Check all speaker wiring.
Reset the Level Control.
Low output.
Check the Crossover Control settings.
Check the RCA interconnect cables.
Check all speaker wiring.
Audio present in
only one channel.
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.
High hiss in the
speakers.
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.
Check for improperly grounded RCA interconnects.
Squealing noise
from speakers.
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.
Distorted sound.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Check that the minimum speaker impedance for the amp model is correct.
Amplifier gets
very hot.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add external cooling fan(s).
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
(static type)
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.
Engine noise
(alternator
whine)
