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.
Input Gain
The WCC-D2400 and WCC-D5000 amplifiers have level adjustments to allow for easy integration with any source unit. The input sensitivity can be adjusted from 200mV to 5V. Refer
to Testing the System and Adjusting the Sound of the System sections of this guide for
detailed instructions on setting the gain.
Phase Switches
● 0° - leaves output unaffected. The output signal is in phase with the input signal.
● 180° - inverts the output. The channel is 180° output of phase. This configuration
is useful for inverting the phase of subwoofers to improve staging in a vehicle.
This is also used when bridging two amplifiers into one speaker (D2400 only).
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 RCAs to the
RCA Inputs and the RCA outputs to your 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.
Internal Crossover Configurations
The crossover section of the WCC-D2400 and WCC-D5000 amplifiers is continuously variable
and extremely flexible. In addition to the variable built-in low-pass filters, the high-pass
crossover incorporates the INTELLi Q feature. This circuit is designed to optimize the performance of WCC subwoofers in all types of enclosures.
9
©2004 Directed Electronics, Inc.
When using WCC 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 the 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 in the middle (12 position), the low-pass crossover is active with a 2nd order (12dB
per octave) slope. When the switch is to the right (24 position), the low-pass crossover is
active with a 4th order (24dB per octave) slope. The low-pass crossover is continuously variable from 30Hz to 250Hz.
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 (ON position), the high-pass crossover is active with a 2nd order (12dB
per octave) slope. The high-pass crossover is continuously variable from 10Hz to 150Hz and
is optimized for use as a subsonic filter. Additionally, boost can be added at the high-pass
crossover frequency for improved bass output while still protecting the woofer from excessive excursion. The INTELLi Q adjustment allows up to 10 dB of boost at the selected
crossover frequency.
WARNING! Exercise caution when setting INTELLi Q. Maximum boost can potentially
cause woofer damage due to over-excursion.
Fine Tuning the Crossovers
The low-pass and high-pass crossover sections are each marked at four frequency points for
ease of system adjustment. The low-pass crossover section is marked at 30Hz, 50Hz, 150Hz,
and 250Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and 150Hz.
Specific crossover points can be chosen based on the recommended operational bandwidth
of your speakers.
Adjusting INTELLi Q
Incorporated in the high-pass crossover, INTELLi Q maximizes the performance of a subwoofer. The high-pass subsonic filter removes unwanted bass output from the woofer,
increasing the output of a subwoofer by as much as 3 dB due to the increased mechanical
power handling. Depending on the enclosure, using INTELLi Q can increase the low frequency response by an additional 10dB! The type of enclosure used and the woofer's excursion capability determine acceptable boost levels. Listed below are recommended boost levels for different enclosure designs.
10

Infinite Baffle Example High-Pass Set at 30Hz
By removing low frequency signal that the woofer cannot produce, the woofer can play its
capable range louder. The first example is an infinite baffle situation. The left graph displays
the frequency response of a 12-inch woofer in an infinite baffle application without the
high-pass filter, with the filter and with the filter and the INTELLi Q set to +3dB. As you can
see, with +3dB of boost and the high pass filter set to 30Hz, the woofer has more output
down to 25Hz and less overall excursion when compared to the non-high-pass response.
Maximum physical excursion capability of the woofer is 15mm.
NOTE: The left graph is the response; the right graph is the driver excursion. These des-
ignations apply to the following graphs as well.

Sealed Example High-Pass Set at 20Hz
This sealed example is the same 12-inch woofer in the recommended sealed enclosure. Up
to 6 dB of boost is capable if 20 Hz was used. With +6dB of boost, the woofer has more output down to 15 Hz.
Sealed Example High-Pass Set at 30Hz
In this example, the frequency has been increased to 30 Hz. Up to 6 dB of boost is capable
at this frequency. With +6dB of boost, the woofer has more output down to 23 Hz. The
overall usable output is increased.
Vented Example High-Pass Set at 30Hz
Vented enclosures benefit most from the INTELLi Q. Up to 10 dB of boost is capable at the
box tuning frequency of 30 Hz. With +10dB of boost, the woofer has more output down to
22 Hz. The excursion below the tuning frequency has been greatly reduced.

Remote Gain Operation
The remote gain port provides easy remote access to the internal gain structure of the
power amplifier. The RGC-1 plugs into the amplifier via the 1/8" mini jack plug. The RGC-1
can be installed in the front of the vehicle to control the amplifier gain level. The RGC-1 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 sub amplifiers. Plug the RGC-1 into the first
amp that must have its RCA output selection switch in the MASTER position. The RGC-1
information will now be sent to subsequent amps via the MASTER signal.
Note: The RGC-1 is not supplied with the amplifier (order Orion p/n 58000).

● Add an extra ground wire between the negative terminal of the battery and the
chassis. Either dual 4 AWG or single 1/0 AWG is recommended.
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 is recommended because the current delivery of the factory electrical system was designed
only to accommodate electronics supplied by the auto manufacturer.
WARNING! The WCC-D5000 has two separate four-gauge power and ground inputs.
Both pairs of connections must use 4 AWG power wire for proper operation.
Failure to do this may damage the amplifier and is not covered under warranty. The WCC-D5000 cannot be operated in a bridge or strapped configuration, attempting to do so will damage the amplifier.

Speaker Connections
The WCC-D2400, and WCC-D5000 amplifiers offer two positive and two negative output terminals for ease of connecting the speakers to the amplifier. Since these are mono amplifiers, the
speaker connectors are paralleled internally. Each amplifier is stable to 1W.
Bridging
For bridging into a single speaker load, the WCC-D2400 has the ability to be bridged with
another amplifier of the same model. To do this you must utilize the COPY/GAIN/MASTER
switch settings. For the MASTER amplifier, set the switch setting to MASTER. This will route
the signal through RCA to the other (slave) amplifier. Refer to Auxiliary Output
Configuration section of this guide. To set the PHASE switch on the (slave) amp, move the
phase switch from 0 to 180, exactly opposite of the master amp. Refer to the Phase Switches
section of this guide.
On the (slave) amplifier be sure to turn off all crossovers. For the speaker connections, connect the positive (+) speaker lead from the speaker to the positive (+) speaker terminal of
the master amplifier. On the negative (-) speaker connection, take the negative (-) speaker
terminal of the master amplifier and connect it directly to the negative (-) speaker terminal
of the (slave) amplifier. The remaining positive (+) speaker terminal of the (slave) amplifier
must be connected to the negative (-) speaker lead from the speaker. The impedance of the
speaker must not exceed 2W.
NOTE: For best results, connect both negative speaker terminals on the master amp to
both negative terminals on the slave amp using at least 12 AWG cable.
WARNING! The WCC-D5000 is not designed to work in a bridged or strapped configura-
tion. Attempting to apply these configurations will damage the amplifier
and will not be covered under warranty.

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 RCAs 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)
● RTA (real time analyzer)

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
16

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 REM).
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 RCA
connections 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 cor-
responding 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.
