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)
