DESCRIPTION
• The Clarion DPX1000.2 two-channel amplifier provides 250 watts x2 into a 4
ohm load, 450 watts x2 of power into a 2 ohm load. and 500 watts x2 into a 1
ohm load. This full featured model is an excellent choice for a variety of car
audio sound system configurations.
• The DPX1000.2 is Clarion’s first amplifier using Digital Technology
The DPX1000.2 uses an unregulated MOSFET power supply for superior
control of output wattage. A toroid-coil transformer yields maximum power
transfer with minimum heat loss. Careful attention to circuit design keeps AM
RFI at low levels, so you won’t hear unwanted noise when the level is cranked
up. Protection circuits safeguard the amplifier when overheating and speaker
shorts or improper load conditions occur.
• All connections and controls of the DPX1000.2 are on the end panels and are
easy to understand. We use gold-plated RCA and barrier connectors to ensure
the best electrical connection for your system. Included is a wired remote sub
level control (BC2) for adjusting the amplifier gain from the front of the
vehicle.
• Multimode operation is a unique feature that allows the DPX1000.2 to
maximize power output at different loads. In the regular mode (loads of 4 ohm
or 2 ohm stereo), the power output is 250 watts x2 into 4 ohms and 450 watts x
2 into 2 ohms. With a 1 ohm load, the power output will increase to 500 watts
x 2. This feature will accommodate various system configurations
Note: Activation of the 1 ohm mode will occur when the output load is 1 ohm.
The amplifier will shut down for 15 seconds and then turn back on in the 1
ohm mode. To reset this feature, the power connections must be disconnected
for 30 seconds and then reconnected.

DESCRIPTION
INPUT CONNECTIONS AND AUDIO CONTROLS
The front panel of the DPX1000.2 contains connections for RCA Inputs,
Speaker Level Inputs and Audio Controls as shown below.
The RCA Input Connections are gold-plated RCA Jacks and are labeled as
RIGHT and LEFT.
• Remote Sub level Control - This port is for the supplied remote gain control
that allows adjustment from a remote location .
• Subsonic Filter - This switch will activate the Subsonic Filter Circuit which
eliminates unwanted frequencies from 24Hz and below.
• Gain Control - This allows you to set the nominal operating level of the
amplifier. The amplifier ’s range, 250mV to 2.5V for RCA inputs or 500mV to
5V for speaker level inputs, can accommodate input levels from virtually any
brand of source unit.
• Bass Boost Control- The amplifier also features a “high-Q” (i.e. narrow
frequency band) Bass Boost circuit. It acts much like an equalizer, with
adjustable gain (from 0 to +15dB) fixed at 45Hz. Use this feature to tune lowfrequency audio response to compensate for a less than ideal subwoofer
enclosure design. The added boost produces rich, full bass tones that are
normally difficult to reproduce in the car audio environment. Note: If Bass
Boost is undesired, set Bass Boost to 0dB.
Low-pass Filter Controls
• Frequency (Hz) Selection Control - The crossover frequency is fully
adjustable between 55Hz and 550Hz for a wide range of crossover points. Use

this feature, along with your speaker manufacturer’s recommended crossover
frequencies, to quickly design a more advanced system
• X-Over Slope Switch - This switch will change the X-Over between a 12db
and 24dB per octave slope. The steep crossover slope keeps midrange tones out
of the subwoofer and thereby eliminates an unnatural “nasal” tone quality in
the audio system.
• Output Mode Switch - This switch is to change the output between lowpass
and fullrange. If lowpass is selected, the lowpass filter controls will control
the crossover frequency.
• Input Mode Switch - This switch allows you to set the input mode. Stereo
input allows full left and right stereo operation. Right (bridged) input allows
single channel input for bridged operation. This is especially useful in highpowered systems when using one amplifier for each subwoofer/speaker. L + R
(sum mono) allows a stereo input to be summed into a mono output.
• Speaker Level Inputs - These provide connections for a high-level stereo
source. In addition, these connections are provided for installations where the
source unit’s RCA outputs are unavailable.
WARNING:When using the speaker (high-level) inputs, the Black wire must
be grounded at the Radio. Failure to do this will result in noise and improper
operation.

INSTALLATION
This section lists Mounting and Wiring Precautions for installing the Clarion
DPX1000.2. These safeguards provide enough detail to successfully complete
an installation. If you do not have the necessary skills, Clarion recommends
consulting your authorized Clarion dealer for installation.
MOUNTING PRECAUTIONS
Although the Clarion DPX1000.2 incorporate heat sinks and protection circuits,
mounting the amplifier in a tight space without any air movement can still
damage internal circuitry over time. Choose a site that provides adequate
ventilation around the amplifier. For easy system set-up, mount the amplifier
so the front panel controls will be accessible after installation.
In addition, observe the following precautions:
1. For the most efficient cooling, mount the amplifier so cool air runs along the
length of the fins rather than across them. Remember, any moving air will
dissipate heat.
2. Mount the amplifier on a rigid surface. Avoid mounting to subwoofer
enclosures or areas prone to vibration. Do not install the amplifier on plastic or
other combustible materials.
3. Prior to drilling, make sure proposed mounting holes will not cut into the
fuel tank, fuel lines, brake lines (under chassis) or electrical wiring.
WIRING PRECAUTIONS
Read all wiring precautions. If you are not sure of the connections, contact
your authorized Clarion dealer.
1. Before installation, make sure the source unit Power switch is in the OFF
position.
2. Disconnect the negative (-) lead of the battery before making any power
connections.
3. When making connections, be sure that each connection is clean and secure.
Insulate final connections with electrical tape or shrink tubing. Failure to do so
may damage your equipment.
4. A secure clean ground connection is critical to the performance of your
Clarion amplifier. Use the shortest ground wire possible snd securely connect
to the car chassis to minimize resistance and avoid noise problems.

INSTALLATION
5. Add an external fuse on the amplifier ’s positive (+) power lead and connect
it as close as possible to the vehicle’s (+) battery terminal. Use a rating that
equals the total current consumption at full output of all amplifier in the
system. Adding an external fuse will protect the electrical system from short
circuits that can cause a fire.
6. Refer to Figure 6 when making electrical connections. Connect the
amplifier’s positive (+) lead via a fuse directly to the positive (+) terminal on
the battery. Do not connect this wire to the car ’s fuse panel. Use red-insulated
10-gauge (or larger) wire for the amplifier’s positive (+) power lead and the
same-gauge black-insulated wire for the ground.
7. When replacing the amplifier’s fuse, always use one having the same current
rating. Substituting a higher-rated fuse or a slow-blow type can result in serious
damage to the amplifier.
8. Never ground the speakers to the vehicle chassis or body.
9. Make sure that your vehicle’s electrical system (alternator, battery, etc.) is
capable of handling the additional load. If you are planning a multi-amplifier
system, you may need to add a second battery and possibly upgrade the
alternator with a higher-output rated model. Consult your authorized Clarion
dealer for recommendations.
10. To avoid noise problems, run the amplifier’s positive (+) power lead along
one side of the vehicle to the battery. Run the remote turn-on wire and RCA
audio cables down the center, and route the speaker wires along the remaining
side. If wires must cross, run them perpendicular to each other.
11. When creating passage holes for the power wire, use grommets to eliminate
any sharp edges created during drilling. This will protect the wire from being
nicked and causing a short circuit.
12. Extra cable can cause signal loss and act as an “antenna” for noise. Use
only high-quality RCA cables that are no longer than necessary to make a
direct connection with the source unit or equalizer.

SETTING THE GAIN
After completing the installation, follow these steps to set the Gain Control and
then perform the Final System Checks.
1. Turn the Gain Control all the way counter-clockwise.
2. Turn the vehicle’s Ignition Switch to the ON position. Then turn the
ON/OFF Switch on the source units to the ON position. Set all Tone or
Equalization Controls to “flat” positions and turn Loudness off.
Note: If the system uses an equalizer, set its frequency controls to “flat”
positions.
3. Play a CD or Tape and set the Volume Control at 75% of full level.
4. Slowly increase the Gain Control. Stop when you hear a slight distortion of
audio.
SETTING THE
CROSSOVER
The Clarion DPX1000.2 features a fully adjustable crossover. To set the
crossover, follow these steps.
1. Using the Amp Mode Switch, select the desired mode - Low Pass, or Full
Range.
Note: Fullrange selection will disable x-over adjustments.
2. Using the Freq (Hz) Control, select the desired frequency.
SETTING
THE BASS BOOST
1. Initially set the Bass Boost control to its full left position (i.e. 0dB).
2. Listen to a variety of music styles (e.g. Rock, Rap, etc.) and slowly increase
the Bass Boost control until a noticeable increase in low bass response is
perceived.
3. Slowly adjust the Bass Boost control (up or down) to realize the best bass
response.
CAUTION: If you hear a “pop” (due to speaker over-excursion), lower the
Bass Boost to prevent speaker damage. If the system sounds muddy and
distorted (due to amplifier clipping), lower Bass Boost to avoid shutdown from
overheating.

SETTING THE GAIN
FINAL SYSTEM CHECKS
1. Start the engine and turn on the source unit. After a two-second delay,
slowly increase the Volume Control and listen to the audio. If you hear any
noise, static, distortion or no sound at all, check the connections, and also refer
to Troubleshooting. Depending on your system design, the levels may become
quite loud even at low Volume Control settings. Until you get an “audio feel”
of the system’s power, use care when adjusting controls.
2. Turn the Balance Controls to their extreme positions and listen to the results.
Audio imaging should match control settings (audio from the left speaker when
balance is left).
3. Increase the volume and verify that the amplifier reproduces audio (at full
frequencies) without distortion. If you hear distortion, check the connections
and verify that the Gain Control is set correctly. Another possibility is
damaged speakers or under-powered speakers. Once again refer to
Troubleshooting for additional help.
