OUTPUT CONFIGURATIONS
Three position switches determine output configuration for the XTREME amplifiers. Each stereo pair of channels can be configured in either stereo,
summed-bridged and bridged-mono. The switch or switches are located on he outermost edge of the amplifier.
When the switch is in the left position, the output channels are configured for stereo operation.
When the switch is in the center position, the output channels are configured for summed mono operation by
mixing the left and right input signals together.
When the switch is in the right position, the output channels are configured for a single bridged output using a
single RCA input. To determine which RCA to use, refer to the marking in parenthesis. For the front outputs, the Left
RCA input is used. For the rear outputs, the Right RCA input is used.
4-CHANNEL AMPLIFIER INPUT CONFIGURATIONS
The 2-channel input / 4-channel input switch routes RCA input from the front RCA inputs to the rear section of the amplifier. This
allows the XTREME 4-channel amplifier to utilize a single set of RCAs to feed signal to both the front and rear channels of the
amplifier.
When the switch is in engaged, signal from the front RCA input is routed to the rear RCA inputs.
NOTE: In this configuration, the rear RCA inputs can be routed to another amplifier. The signal leaving the amplifier is a copy of
the incoming signal.
When the switch is disengaged, front and rear RCA inputs are independent. This allows a source unit with an internal fader to
fade between the front and rear outputs.

Download from Www.Somanuals.com. All Manuals Search And Download.
RCA INPUT / CH 1 & 2 XVR
The RCA Input / 1 & 2 XVR push button switch configures the input for Channels 3 & 4. The feature allows the more
advanced crossover features of the front channels to be routed to both the front and rear channels. Configured in this
manner, INTELLiQ is now available on all channels of the amplifier as well as bandpass crossovers for midbass and
midrange speakers.
When the switch is disengaged, the rear RCA input feeds channels 1 & 2.
When the switch is engaged, channels 3 & 4 receive input signal from the output of channels 1 & 2 after the crossover
output. When the switch is in engaged, signal from the front RCA input is routed to the rear RCA inputs. The front gain
control controls the level of the entire amplifier. The rear gain controls are deactiviated.
REAR INTERNAL CROSSOVER CONFIGURATION
The XTREME 600.4 use multi-position switches to determine the rear crossover configuration. The multi-position switch is located on the adjust-
ment side of the amplifier. Listed below are the switch positions and their respective crossover configurations.
When the switch is in the “OFF” position, the crossover section of the amplifier is bypassed. Amplifier output is full
range.
When the switch is in the center position, the crossover is configured for high-pass operation. The rear channels of
the XTREME 600.4 are continuously variable from 45Hz to 5kHz.

REAR INTERNAL CROSSOVER CONFIGURATION
When the switch is in the right position, the crossover is configured for low-pass operation. The rear channels of the
XTREME 600.4 are continuously variable from 45Hz to 5kHz.
FRONT INTERNAL CROSSOVER CONFIGURATION
The front channels of the XTREME 600.4 can be configured for either high-pass, low-pass or bandpass operation. INTELLiQ is a feature of the

INTELLi Q (INTELLigently integrated Q adjustment) is actually an infinitely variable “Q” adjustment found
on the high-pass crossover of new XTREME and HCCA “Type R” power amplifiers. By changing the “Q” of
the high-pass from the industry standard 0.707 to any “Q” value between 0.707 and 3.5 (Fig u re 1), the
high-pass filters essentially becomes two filters: a single band parametric equalizer and a subsonic filter.
By increasing the “Q” value from 0.707 to 3.5, the output is boosted up to 10dB at the high-pass crossover
frequency. The end-panel display is clearly marked in 3dB boost steps. Unlike other manufacturers
“subsonic filters,” adjusting the INTELLi Q’s high-pass crossover frequency easily performed turning the
crossover pot located directly to the right of the “Q” adjustment (Fig u re 2). The high-pass crossover is
continuously variable from 10Hz to 1kHz or 100Hz to 10kHz via a x10 frequency selector. By correctly using
the INTELLi Q, you can increase low frequency output by as much as 10dB!
Boosting the lower bass frequency does not come without trade-offs. As anyone knows, one of the
greatest potentials for woofer damage is caused by over excursion. Excursion is the forward and backward
movement of a woofer. When the signal to the woofer is incorrectly boosted, the woofer is required to
move more than is capable. For reference, a 6dB of boost requires a woofer to quadruple its excursion to
match the input signal. Ordinary bass boost equalizers boost without protection. Without any protection,
potential for damage is high.

What makes the INTELLi Q different from all other equalizers or sub-sonic filters is that it can boost lower
frequencies the woofer can produce by 10dB while preventing over excursion that can damage the woofer.
The result is your woofer with the loudest low bass it can produce reliably. Here’s how to use it.

INTELLI Q
Setting up and using INTELLi Q
1. The first step to using the INTELLi Q is to install the amplifier. Seriously, basic installation techniques for new XTREME and HCCA “Type R”
amplifiers remain unchanged. Set the low-pass crossover as you would in “normal” installations. (Normal Orion of course.)
2. Determine which type of enclosure you are using. Refer to the table below for tuning assistance. For example: for vented enclosures, set the
high-pass crossover to the tuning frequency (port frequency) of the enclosure. If you have a woofer such as the new HCCA woofers up to
10dB of boost can be used. For woofers of lesser excursion capability, it is recommended to use up to 6dB of boost only.
3. For RTA tuning, start the INTELLi Q boost setting at 0dB. Using pink noise, slowly increase the Q adjustment until the desired frequency
response is achieved. In situations where you are require more boost than is recommended, you can lower the crossover frequency to get a
similar desired effect.
4. For tuning by ear, start the INTELLi Q boost setting at 0dB. Using music the high-energy low frequency content, slowly increase the Q
adjustment until the desired sonic performance in achieved. In situations where you are require more boost than is recommended, you can
lower the crossover frequency to get a similar desired effect

REMOTE GAIN
The remote gain port allows remote, user control over the output of the amplifier. When used on a
subwoofer amplifier, the remote gain allows you to change the bass level for different music styles, driving
conditions, or sonic preferences. Unlike other designs, Orion allows remote access to the level of the
amplifier via a digital micro-controller and electronic volume that does not interfere with the sonic signal
chain. The result is a clean clear control of the level of the amplifier that is unaffected by noise.
The XTREME 600.4 has two remote gain ports. This allows for individual control of either the front or rear
channels. One RGC-1 can be used to control the level of the front channels and another RGC-1 can be used
to control the output level of the rear channels. An example benefit of this is having the front channels in
bandpass mode for midbass and the rear channels in low-pass mode for subwoofers. Using two RGC-1 would
give the driver the ability to control the level of both the midbass and subwoofers for easy optimal tuning.
To utilize this function simply plug-in a RGC-1into either the front or rear gain ports. The RGC-1 is available
from your authorized ORION dealer. T
SIGNAL INPUT AND OUTPUT LEVEL CONTROLS
XTREME amplifiers have separate front and
rear level adjustments. The input sensitivity
of these adjustments range from 200mv up
to 5Vrms on the RCA inputs. This allows easy
integration from any source unit either with
RCA outputs or speaker outputs. Refer to
the Testing the System and the Adjusting
the Sound of the System sections for
detailed instructions on setting up the level
controls.

CHOOSING MOUNTING LOCATIONS
The location of your XTREME amplifier will depend on several important issues. Due to the low profile size of the XTREME amplifiers, there are
many possible installation locations that will yield satisfactory amplifier performance. Always mount the amplifier in a place that protects the
amplifier from the elements. In addition, mount the amplifier on a stable, flat mounting surface. As with any amplifier, there are several
possible mounting locations and configurations that can be optimal. We will cover the most obvious of situations.
PASSENGER COMPARTMENT
If you are going to mount the amplifier in the passenger compartment, make sure you have
adequate room for ventilation. XTREME amplifiers have been designed to make possible under seat
mounting. When mounting your amplifier under a seat or similar area, keep a minimum of 1” of
clearance around the amplifier for adequate cooling.

TRUNK COMPARTMENT
Mounting XTREME amplifier in the trunk provides excellent performance as long as you do not
mount the amplifier upside down or restrict the airflow around the heatsink of the amplifier. For
optimal results, mount the amplifier with the cooling fins in the vertical position. This type of
mounting will yield the best cooling due to the convection effect of the amplifier chassis.

GENERAL PRECAUTIONS AND INSTALLATION TIPS
Caution: Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your
vehicle.
Disconnect the vehicle’s ground wire at the battery before making or breaking connections to the audio system’s power supply te rminals.
Do not use the XTREME amplifier unmounted. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of
an accident. An unmounted amplifier acts like a heat-seeking missile in the event of a crash. Never mount a XTREME amplifier where it might
get wet. Mount the XTREME amplifier so the wire connections will not be pulled. Route the wires where they will not be scraped, pinched or
damaged in any fashion.
The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 18”. Use the recommended fuse size or
circuit breaker listed in the Power Connections section of this manual.
If you need to replace the fuse plugged into the side of the XTREME amplifier, replace the fuse with the same size ATC type fuse that came with
the amplifier. If you are not sure as to the correct value, refer to the Power Connections section of this manual for details. Using a higher
current fuse may result in damage to the XTREME amplifier which is not covered under warranty.
NOTE:
Make sure all the equipment in the system is turned off when making or breaking connections to the XTREME input RCAs or speakers
terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections.
Power for systems with a single XTREME amplifier can be supplied by most any automotive electrical system. Systems with multiple amplifiers
may require a higher capacity battery, alternator or the use of a storage capacitor. WE strongly recommend the use of both a Transient Storage
Capacitor and a MBR70 with an extra battery in larger stereo systems.
XTREME amplifiers generate a certain amount of heat as part of normal operation. Be sure the area around the cooling fins is unobstructed to
allow adequate air circulation. Remember, beach blankets, last weeks laundry, school books and homework papers located on top of the
amplifier, do not improve air flow.

STEP BY STEP INSTALLATION
Step 1
Step 2
Step 3
Determine the location for the amplifier. Refer to the Mounting Locations section in this manual for detailed information.
Decide on the system configuration for your amplifier. For system suggestions, refer to the System Planning section of this manual.
Run all the wires from the amplifier location to the speakers, source unit and battery. Do not connect the battery at this time. Be sure to
run RCAs, power and speaker wires away from factory electrical wires and system as they pose a great potential for induced system noise.
Step 4
Step 5
Pre-drill amplifier mounting holes. Be sure to "think before you drill". Gas tanks, fuel lines, and other obstructions have a nasty way of
hiding themselves. For best results use a marking pen to mark the mounting holes and pre-drill these holes with a standard 1/8" drill bit.
Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If this is not possible, do not over tighten the screws such that
the chassis of the amplifier is twisted or bent.
Step 6
Step 7
Step 8
Turn the vehicle’s key switch on the off position.
Disconnect the vehicle’s battery ground terminal.
Connect the RCA and speaker wires to the amplifier. Check the quality of your speakers and signal connections. This will determine the
ultimate performance of your ORION amplifier. Refer to the Input section of this manual for correct wiring instructions.
Step 9
Connect power wires to the amplifier. At this time do not connect the fuse at the main battery.
Step 10 Reconnect the ground terminal to the battery.
Step 11 Set crossovers. Refer to the Internal Crossover Sections of this manual for detailed instructions.
Step 12 Once satisfied that all connections and settings are correct, install the fuse at located near the vehicle’s battery and proceed to the testing
the system section of this manual.
WARNING! Never exceed the recommended fuse size of this amplifier. Failure to do so will result in the void of your warranty.

TESTING THE SYSTEM
After you have completed the installation, you need to test the system. This will help ensure years of trouble-free operation. Please refer to the
listed steps below when testing the sound of your ORION XTREME system.
Step 1 Check all the wiring connections to be sure they are correct and secure.
Step 2 Turn the signal source volume control down all the way. Set any tone controls to their flat or defeated positions. This includes the
loudness control.
Step 3 Turn the level controls of the amplifier to their minimum positions.
Step 4 Turn the source unit on. Check to see if the remote power LED locate on the connection side of the amplifier is lit. If not, please refer
to the power connections section and the trouble shooting section of this manual for instructions.
Step 5 If using a aftermarket source unit, turn the level controls of the amplifier about one quarter of a turn. Slowly increase the volume level
of the source unit to so that you can hear the output of the system. If no sound is heard or if the output is distorted, turn the system
off immediately. Refer to the power connections section and the trouble shooting section of this manual to solve your installation
problems.
Step 6 Check to make sure the output for each channel is correct. If the active crossovers are used, check to make sure that ea ch output is
correct from the amplifier. When using active crossovers on midrange and tweeters, do not use crossover frequencies lower than
recommended. If the system is not configured properly, refer to the internal crossover section of this manual and take corrective
action.
Step 7 If the output is clear and undistorted, continue to the adjusting the sound of the system section of this manual.

ADJUSTING THE SOUND OF THE SYSTEM
Once you have checked the system’s operation, adjust the sound of the system. Adjusting the sound of the system is accomplished by setting the
level controls and adjusting the internal crossovers.
Step 1 Turn the signal source volume control down all the way. Set any tone controls to their flat or defeated positions. This includes the
loudness control.
Step 2 Turn the level controls of the amplifier to their minimum positions.
Step 3 Choose music with high dynamic content that you like and that you are familiar with and will be most often used in the system.
Step 4 Turn the unit up to its highest undistorted output level. If you lack test equipment, this point occurs between 3/4 to full volume depend-
ing on the quality of your source unit. Listen for any audible distortion, if any distortion is audible, reduce the volume of the source unit
until you have an undistorted output. Leave the volume control at this position during your system tuning.
Step 5 While listening to your chosen dynamic music, turn up the level control corresponding to the midrange output until you hear slight
distortion and turn back the level control slightly for an undistorted output. Depending on your system the midrange and tweete r output
may be on the same output channels.
Step 6 Turn up the level control corresponding to the tweeter output until you hear slight distortion and turn back the level control slightly for
an undistorted output. Depending on your system the midrange and tweeter output may be on the same output channels.
Step 7 Fine tune crossover setting and output level between midrange and tweeters. Refer to the internal crossover section of this manual for
detailed instructions.
Step 8 Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers continue to Step 10.
Step 9 Set levels between the front and rear midrange and tweeters for optimum front/rear balance.
Step 10 Turn up the level control corresponding to the woofer output until you hear slight distortion and turn back the level control slightly for
an undistorted output.
Step 11 Fine tune crossover setting and output level between satellite speakers and the woofers. Refer to the internal crossover section of this
manual for detailed instructions. If using an RGC-1, adjust the level to match the output of the woofer to match the sonic requirements
of the system.
Step 12 Enjoy your awesome ORION sound system.

AUTOSOUND 2000 TROUBLESHOOTING TIPS
QUICK CHECK FOR TROUBLESHOOTING CAR AUDIO SYSTEMS
Preface:
All audio systems exhibit noise; however, if the level of noise is low enough, and the signal level high enough, noise should
not be a problem. This means that it is very important that the signal level throughout the system be optimized BEFORE
dealing with your noise problem. Using a scope (or a small portable amplifier) and Track 99 (1kHz at all high bits) of
Autosound 2000’s CD #101, or tracks 24 through 29 of Autosound 200’s CD #102, adjust the system so that when the maximum
usable signal level of the deck is fed into the system, all the preamp level components clip at the same time. However, we
recommend up to as much as a 3:1 voltage overlap with the power amplifiers; i.e. an amplifier with a 2 volt minimum sensi-
tivity can be driven by up to 6 volts of signal.
Noise Overview:
Car audio electrical accessories are notorious for interfering with car audio systems. The interference commonly arises from
three areas:
1) Power line noise (5% ), which can be attenuated with in-line noise filters,
2) Inadequate power supply isolation (45% ), which can be cured with transformer signal coupling, additional isolated power
supplies, or changing out components, or
3) Inductive interference (45% ) - Including loop area inductive noise picked up by the signal cables - which can be remedied
by relocating or rewiring components, rerouting signal cables, or using twisted cable or balanced transmission systems.
AUTOSOUND 2000 1-2-3 METHOD OF LOGICAL TROUBLESHOOTING
I.
MUTE THE AMP(S). Insert a muting plug (shorted male RCA connector) into each amplifier channel. Turn up the amp sensitivity. Start the car
and turn on the headlights, air conditioning, brake lights, etc. Listen for noise in each speaker. Be very picky here!
A. If still noisy, substitute a small test speaker with short leads for the speakers, crossovers, and speaker leads in the car. If still noisy,
substitute an isolated power supply (120 VAC to 13.8 VDC bench supply or a small motorcycle battery) for the car’s alternator. If the
amplifier is noisy with the test speaker, you have a BAD amp. Send it in. It really doesn’t matter if it is quiet or noisy while running on the
isolated supply because you have a BAD amp. Send it in for repair and if it was quiet on the isolated supply, indicate so on the repair tag.
page 40
Download from Www.Somanuals.com. All Manuals Search And Download.
B. If your muted amp is quiet, you’ve just joined 99.5% of car audio. Amps are usually very clean and do NOT pick up
unwanted noise! Continue on to Step II.
II. DECK TO AMP. Using a new set of signal cables, connect one channel from the output of the deck directly into one
channel of your clean amp. Run the cables outside the car and as far away as possible from the metal of the car. (For
noise purposes, consider a 2" thick cushion of electromagnetic energy emanating from every metal surface in the car.)
A. If still noisy, congratulations, in all probability your equalizer, electronic crossover, DSP whatchamacallit, are just fine.
This means that you can’t get your deck playing quiet with your amp, right? go to Step III.
B. If all is quiet, congratulations, in all probability your deck and amplifier(s) are fine - you obviously have a problem
with your equalizer, electronic crossover, DSP, etc. Skip on down to “Time for the Processors.”
III. MOVE THE DECK. If you’re at this step, it is time to turn your system into an “amplified deck” by temporarily relocating
the deck right ON TOP of the clean amplifier. Then using very, very short signal cables, connect the output of the deck
into the input of the amp and test for noise. Play a zero bit track - silence - and make sure all is completely quiet.
A. If still noisy, you’re in a heap of trouble, We suggest that you try another deck and give us a call so that we can put
your name into the record books. It’s a bad car audio day for you.
B. If the deck is quiet, then congratulations, you’re on your way to a successful installation. It is now time to slowly,
methodically, reinstall the deck back into its final position. Test for noise each step of the way. If the noise returns,
suspect the signal cables, forget shielding because it will have only a very, minimal effect within the audio band. We
highly suggest using twisted pair cables or a balanced transmission system for cable induced noise.
TIME FOR PROCESSORS
By the end of Step III, you should have the deck playing quietly with the amp, with the quiet cables quietly routed. So it’s
time to add the signal processors - one at a time - back into the system. Simply repeat Steps II and III with the equalizer, then
the electronic crossover, etc. However, before MOVING THE SIGNAL PROCESSORS to the amplifier, we highly suggest that
you supply power to the noisy processor from an isolated power supply rather than the car’s +12 volt DC and chassis ground.
Make sure to also connect the turn-on lead to the isolated power supply. If the processor is now quiet , then it is highly

probable that the component has inadequate isolation. Solutions include, changing components or permanently adding an
external isolated power supply (Call Autosound 2000 at 209-465-3450 for info on isolated power supplies).
SUMMATION
During the design stage of your vehicles, try to avoid using extra batteries and high output alternators. Extra batteries are
nothing but loads as soon as the engine is started and high output alternators usually make more noise than stock alterna-
tors. Also, extra batteries installed in the trunk of a car will ALWAYS force extra ripple current to flow over the car.
Install Transient Storage as close to the power supply input of your amplifier as possible. The big caps will feed the switching
power supplies of your amps and minimize the inductive losses in your power wiring. Plus, they will help your peak system
response.
In problem cases, we highly recommend the use of twisted pair cable rather than coaxial cable for RCA leads. This practice
will greatly minimize cable induced noise - especially in four channel amps!
Don’t forget that your system is only as good as its worst component. Do NOT use components with inadequate power supply
isolation or you will be asking for problems.
The best electrical ground on a car is the CHASSIS of the car. Do NOT run ground leads up to th
e case of the alternator or the negative battery post. Keep ALL ground leads as short as possible.
With properly isolated components, it does NOT matter where the component is grounded. With inadequately isolated
components, it matters! With poorly isolated components, different grounds can cause different noises.
The deck is the signal reference ground for the entire sound system. The deck usually has THREE connections to the car’s
chassis: The black ground lead, the base of the antenna, and the metal-to-metal bond between the case of the deck and the
chassis of the car. With three grounds, there is usually NO cause to worry about the ground of a deck.
Amplifiers are usually designed with adequate power supply isolation. This means that it should not matter where a deck is
grounded. (Decks are grounded three times and amps float. This is car audio!)

The more components installed on a signal path, the more chances for noise to enter a system. The more electrical accessories
on a car, the more noise will be produced by the alternator.
