AMPLIFIER SETTINGS
Signal Input and Output Configurations
The input section of the amplifier consists of a phase switch that sets the output configuration, gain controls, and RCA inputs. The input section makes it easy to adapt this amplifier
to most system configurations.
Four-Channel Amplifier Input Configuration
The 4CH / 2CH switch routes input from the front inputs to the rear section of the amplifier. This allows the WCC-1600.4 amplifier to utilize a single set of RCA's to feed signal to the
front and rear channels of the amplifier.
When the switch is to the right (2CH position), signal from the front inputs is routed to the
rear channels.When the switch is to the left (4CH position), front and rear inputs are independent. This allows a source unit with an internal fader to fade between the front and rear
outputs.
Internal Crossover Configuration
The crossover section of the WCC-1600.4 amplifier is continuously variable and extremely
flexible. There are eight different crossover configurations possible allowing high-pass, lowpass, and band-pass operation. This circuit is designed to optimize the performance of subwoofers in all types of enclosures.
When using loudspeakers, minor deviations from the recommended frequency ranges can
provide superior results depending on your speaker locations and your vehicle acoustics.
Setting crossover frequencies higher than recommended will not cause damage and may
provide superior sonic results depending on your system's performance goals. Refer to your
loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for
your system.
WARNING! DO NOT set crossover frequencies lower than the speakers recommended
operating range. This can cause driver failure that is not covered by manufacturer's warranty.
Low-Pass Crossover
When the switch is to the left (OFF position), the low-pass crossover is bypassed. When the
switch is to the right (LP position), the low-pass crossover is active. The low-pass crossover is
continuously variable from 20Hz to 3kHz.
High-Pass Crossover
When the switch is to the left (OFF position), the high-pass crossover is bypassed. When the
switch is to the right (HP position), the high-pass crossover is active. The high-pass crossover
is continuously variable from 20Hz to 3kHz.
High-Pass Woofers
The high-pass crossover is continuously variable from 20Hz to 3kHz. The high-pass crossover
is now optimized for use as a subsonic filter for subwoofers. Additionally, boost can be
added for improved bass output while still protecting the woofer from excessive excursion.

Fine Tuning the Crossover Frequency
The crossover section is marked at four frequency points for ease of system adjustment.
These points are 20Hz, 45Hz, 250Hz, and 3kHz. Specific crossover points can be chosen
based on the recommended operational bandwidth of your speakers.
Remote Gain Operation
The remote gain port provides easy remote access to the internal gain structure of the rear
channels of the WCC power amplifier. The RGC plugs into the amplifier via the 1/8" mini
jack plug. It can be installed in the front of the vehicle to control the amplifier gain level,
and can be used as a bass level control when used on an amplifier dedicated to subwoofers.
In addition, one RGC-1 can be used on multiple amplifiers. Plug the RGC-1 into the first amp.
The first amp must have its RCA output selection switch in the MASTER or GAIN position.
The RGC-1 information will now be sent to subsequent amps via the MASTER signal.
The RGC-1 controls the level of the rear channels, prior to the EQ and Crossover controls.
When in 2-channel configuration, it will only control the level of the rear channel.
Auxiliary Output Configurations
The auxiliary outputs on WCC amplifiers offer easy, unlimited system expansion. Routing
signal from a source unit, pre-amplifier, or equalizer is a matter of connecting RCA's to the
RCA Inputs and the RCA outputs to the next WCC amplifier in the signal chain. When the
switch is in the COPY position, the RCA output is an identical copy of the input signal. The
signal passes through a buffer stage so that several amplifiers can be daisy chained without
signal loss or overloading of the source unit. This maximizes the signal output and minimizes the potential for system noise.
When the switch is in the GAIN position, the RCA outputs are buffered through the gain
stage of the amplifier. When the first amplifier in the signal chain is set this way, a remote
gain controller (RGC-1) can be connected to the amplifier and act as a PRE-AMP controlling
the overall level of the system. Following amplifiers are configured in the COPY mode with
their gains set to zero as the GAIN amp is now controlling the gain level for all subsequent
amps. This eliminates the need to gain match multiple amplifiers.
When the switch is in the MASTER position, the RCA outputs are buffered through the gain
stage of the amplifier and filtered through the crossover sections of the amplifier. When set
this way, the amplifier's gain and crossover settings are sent to other amplifiers down the signal chain. This can be useful for configuring multiple subwoofer amplifiers easily in a large
SPL system. All subsequent amplifiers after the master amp will be in the COPY position and
have their gains set to zero and all crossovers turned off. The master amplifier will control
all the functions of the slave amps via the MASTER RCA output signal.
NOTE: The RGC-1 is not supplied with the amplifier (order Orion p/n 58000).

INTELLI BASS CONTROL
INTELLi Bass maximizes the performance of a subwoofer and allows for continuous adjustment of low frequency boost. INTELLi Bass can be adjusted from 0dB to 16dB of boost centered at 45Hz. Initially the Q is very low (wide). As INTELLi Bass is added, the Q rises (narrows). This allows the WCC-1600.4 to overcome acoustic deficiencies in your vehicle. The
type of enclosure used, the sub-woofer's excursion capability, personal preference, and attitude determine acceptable boost levels.
WARNING! Exercise caution when setting INTELLi Bass. Maximum boost can potentially
cause woofer damage due to over-excursion.
AMPLIFIER WIRING
Power Connections
● Fuse Size: 100 AMP MAXI
● Minimum 8 gauge power and ground cable is recommended for acceptable per-
formance.

than 18" from battery.
● Ground amplifier to a good chassis ground as close as possible to the amplifier.
● Add extra ground wire (minimum 8 gauge) between the negative terminal of the
battery and the chassis.
NOTE: The addition of a ground wire from the battery to the chassis of the vehicle
improves the ability of the battery to supply power to the amplifier. This helps
especially in newer vehicles, where the current delivery of the factory electrical
system was designed only to accommodate electronics supplied by the auto manufacturer.

AMPLIFIER INSTALLATION
Choosing Mounting Locations
The location of your amplifier will depend on several important issues. Due to the low profile size of the WCC 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 surface.
NOTE: Mounting amplifiers upside down is not recommended and may cause premature
thermal shutdown.
WARNING! Do not mount any amplifier in the engine compartment. Amplifiers are not
designed to endure the harsh environment of the exterior elements.
Passenger Compartment
If you are going to mount the amplifier in the passenger compartment, make sure you have
adequate room for ventilation. The amplifiers have been designed to make under-seat
mounting possible. 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 your amplifier in the trunk provides excellent performance as long as you do not
restrict the airflow around the heatsink of the amplifier. For optimal results, mount the
amplifier with as much clearance as possible. This type of mounting will yield the best cooling due to the convection effect of the amplifier chassis.
General Precautions and Installation Tips
WARNING! 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 terminals.
Do not use this amplifier unmounted. Failing to securely mount the amplifier can result in
damage or injury, particularly in the event of an accident. An unmounted amplifier becomes
a dangerous projectile in the event of a crash. Never mount the amplifier where it might
get wet. Mount the 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 amplifier, replace the fuse with
the same size ATC / MAXI 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 amplifier that is not covered under warranty.
NOTE: Make sure all the equipment in the system is turned off when making or break-
ing connections to the input RCA's or speaker 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 amplifier can be supplied by most automotive electrical systems. Systems with multiple amplifiers may require a higher capacity battery, alternator or
the use of a storage capacitor. We strongly recommend the use of a Directed Audio
Essentials power capacitor with an extra battery in larger stereo systems.
WCC amplifiers generate a certain amount of heat as part of normal operation. Be sure the
area around the amplifier is unobstructed to allow adequate air circulation. Remember,
beach blankets, last week's laundry, school books and homework papers located on top of
the amplifier do not improve air flow and may become damaged.
Tools of the Trade
Listed below are the majority of the tools required to perform an installation. Having the
proper tools will make the installation that much easier. Some of these tools are necessities;
some will just make the job easier.
● Allen Wrenches (2.5mm and 3mm)
● DMM or VOM
● Electric drill with assorted drill bits
● Grommets
● Heat shrink tubing
● Marking pen
● Nylon tie straps
● Phillips and flat blade screw drivers
● Pliers (standard and needle nose)
● Reference CD with 1 kHz Sine Wave at 0dB level (all bits high)

Step By Step Installation
Step 1 Determine the location for the amplifier. Refer to the Choosing Mounting
Locations section of this guide for detailed information.
Step 2 Decide on the system configuration for your amplifier. For system sugges-
tions, refer to the Speaker Connections section of this guide.
Step 3 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 and
power and speaker wires away from factory electrical wires and system as
they pose a great potential for induced system noise.
Step 4 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.
Step 5 Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If
this is not possible, do not over tighten the screws so that the chassis of the
amplifier is twisted or bent.
Step 6 Turn the vehicle's key switch to the off position.
Step 7 Disconnect the vehicle's battery ground terminal.
Step 8 Connect power wires to the amplifier (ground first, then 12 V(+) and RGC).
Step 9 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 WCC amplifier. Refer to the Signal Input and Output Level
Controls and Speaker Connections sections of this guide for correct wiring
instructions.
Step 10 Reconnect the ground terminal to the battery after power, speaker, and con-
nections are completed.
Step 11 Set crossovers. Refer to the Internal Crossover Configuration section of this
manual for detailed instructions.
Step 12 Once satisfied that all connections and settings are correct, install the fuse
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 voiding of your warranty and possible damage to the amplifier.

SET UP AND TROUBLESHOOTING
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 WCC system.
Step 1 Check all the wiring connections to be sure they are correct and secure.
Step 2 Turn the signal source volume control all the way down. Set any tone con-
trols 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 power LED located on the con-
nection side of the amplifier is on. If not, please refer to the Power
Connections and the Troubleshooting Tips sections of this manual for instruc-
tions.
Step 5 If using an 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 and the Troubleshooting Tips sections 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 each 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 Configuration 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 all the way down. Set any tone con-
trols 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, with which you are
familiar, and will be used most often in the system.
Step 4 Turn the source unit's volume control up to its highest undistorted output
level. If you lack test equipment, this point occurs between 3/4 to full volume
depending 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 corre-
sponding to the midrange output until you hear slight distortion and turn the
level control back slightly for an undistorted output. Depending on your system, the midrange and tweeter 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 the output level between midrange and tweeters. Refer to the
Internal Crossover Configuration section of this manual for detailed instructions.
Step 8 Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers con-
tinue 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 the output level between satellite speakers and the woofers. Refer
to the Internal Crossover Configuration section of this manual for detailed
instructions. If using an RGC-1, adjust the level to the output of the woofer
to match the sonic requirements of the system.
Step 12 Enjoy your awesome Wesst Coast Customs by Orion sound system.
