4.OPERATIONS  
Selecting input voltage  
APX and DPX amplifiers accommodate a wide range of signal input voltages (0.2V to  
8V). This wide range is split up into three ranges, which are accessible through  
switches located in the “Gain” area of the amplifier.  
0.2V-0.6V selects an input sensitivity range between 200mV and 600mV.  
0.6-2V selects an input sensitivity range between 600mV and 2V.  
2V-8V selects an input sensitivity range between 2V and 8V.  
The gain rotary control operates within these voltage windows.  
Note:  
Most decks, even 4V and 5V units do not operate at full output voltage.  
This requires the switch to be set in the 0.6-2V range.  
Setting the operating level  
The gain switches allow you to set the nominal operating level of the amplifier from  
0.2 to 8V for RCA inputs or 500mV to 5V for speaker level inputs. This wide adjust-  
ment range accommodates virtually any source unit brand.  
Once you set the correct range using the IVS, you must adjust the gain to match the  
amplifiers sensitivity to that of the source unit. The gain control is not a volume control.  
It exists only to allow an amplifier to be used with different models and brands of head  
units.  
Improving bass sound  
The amplifiers feature a narrow-frequency band bass boost circuit (known as “high-  
Q”). Acting much like an equalizer, the bass boost control lets you tune low-frequency  
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.  
The APX2180, APX4360, and DPX2250 have a switchable gain that is fixed at  
45Hz. If you don’t want to boost the bass frequencies, set this control to “OFF.”  
The DPX1800 and DPX11500 have a variable-frequency bass boost control from  
30Hz to 125Hz. They do not have a bass boost on/off switch, but a level control that  
goes from 0dB to 15dB.  
CAUTION  
This control can dramatically increase the power output level  
and could cause speaker damage if you over use it.  
8
APX/DPX Amplifiers  
Matching subwoofer output to mid-range speakers  
The DPX1800 and DPX11500 feature a polarity control switch for reversing the  
polarity of the output signal. This can be useful when matching the acoustic output of  
your subwoofers to the output of your mid-range speakers.  
Connecting directly to a head unit  
The amps provide connections directly to a head unit without a pre-amp output, such  
as a factory-installed head unit.  
WARNING  
When using the speaker (high-level) inputs, the black wire  
must be grounded at the radio. Failure to do so will result in  
noise and/or improper operation.  
Care and maintenance  
Cleaning the case  
Use a soft, dry cloth to gently wipe dust and dirt from the unit.  
Do not use benzene, thinner, car cleaner, or other cleaners. These substances may  
damage the unit or cause the paint to peel.  
Servicing the unit  
In the event that trouble arises, never open the case or disassemble the unit. The  
internal parts are not serviceable by the user. Opening any components will void the  
warranty.  
CAUTION!  
Changes or modifications to this product not approved by the  
manufacturer will void the warranty and will violate FCC ap-  
proval.

5. INSTALLATION ANDWIRING  
Read these instructions and the following precautions carefully.  
What is included in the box  
In addition to this manual, the box contains:  
Amplifier  
High-level speaker input harness  
Mounting precautions  
If you lack the necessary skills, do not install the amplifier yourself. See your autho-  
rized Clarion Dealer for installation recommendations.  
This unit is exclusively for vehicles with a negative ground, 12V power supply.  
This unit requires additional mobile audio components for proper operation.  
Choose a location in the vehicle that provides adequate ventilation around the  
amplifier. Although any moving air dissipates heat, cool air should run along the  
length of the fins rather than across them.  
CAUTION  
Although Clarion amplifiers include heat sinks and protection  
circuits, mounting an amplifier in a tight space without any air  
movement will reduce performance and damage the unit’s in-  
ternal circuitry over time.  
The DPX1800 does not have a fan. Install it such that air can  
flow to the bottom of the amplifier.  
The DPX11500 has two fans. Mounted in the ends of the unit,  
they blow through the length of the amplifier. Ensure a 3-inch  
clearance between the power/speaker and the control ends for  
proper ventilation.  
Mount the amplifier on a firm, flat surface away from subwoofer enclosures or to  
any area that is prone to vibration. Do not install the amplifier on plastic or on any  
other combustible material.  
For easy system setup, mount the amplifier so that the adjustment controls are  
accessible after installation.  
10  
APX/DPX Amplifiers  
Always use great care when attaching anything to a vehicle! Check clearances on  
all sides of the planned installation before drilling any holes or installing any  
screws.  
Make sure the holes you plan to drill will not cut into the fuel tank, fuel lines, break  
lines (under the chassis) or electrical wiring. Don’t guess. Check first.  
Wiring precautions  
Read all wiring precautions. If you are not sure of the connections, contact your  
authorized Clarion Dealer.  
Do not open the case. There are no user-serviceable parts inside. If you require  
assistance, consult your Clarion Dealer or an authorized Clarion Service Center.  
Power  
Before you start, make sure the source unit’s power switch is off.  
WARNING!  
To prevent short circuits during installation, disconnect the  
vehicle’s negative (-) battery lead before making any power  
connections.  
Fuses  
To protect the vehicle from fire or explosion in the event of a collision, add an  
external fuse to the amp’s positive (+) power lead and connect it as close as  
possible to the vehicle’s plus (+) battery terminal.  
Use a fuse rated to the total current consumption of the amplifier. Fuses mounted  
near the battery should be ~10 Amps bigger than fuses on the amplifier itself.  
If you are using more than one amplifier, add the total current consumption for the  
entire system and use the closest available fuse. For example, if you’re connecting  
both an APX2180 and an APX4360, install a 100 Amp fuse at the battery.  
Power wire size can greatly affect the performance of your audio system. The  
Power wire size table indicates the minimum power wire requirements for proper  
operation.

Cables  
Whenever possible, route power wire and signal wire on opposite sides of the  
vehicle. This prevents the signal cables from picking up electrically radiated noise.  
Protect all wire from damage. Where a power wire passes through the fire wall or  
near exposed metal edges, protect the wire with a rubber or plastic grommet. Use  
wire loom where possible for further protection.  
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 and amplifiers.  
Make sure each connection is clean and secure. Insulate final connections with  
electrical tape or shrink tubing.  
CAUTION  
Improper connections may result in  
unreliable operation and damage the  
amplifier or the vehicle.

Use the shortest wire possible. Clean off any  
paint, primer or sound deading prior to  
making this connection.  
*This amplifier has no amplifier-  
mounted fuses. Always use a 200  
Amp fuse installed at the battery.  
To minimize resistance and avoid noise  
problems, securely connect the ground wire  
to the car chassis and the source unit ground. Using existing bolts is not recom-  
mended.  
The last connection you make should be the ground wire at the amplifier. As the  
power supply capacitors in the amplifier are not charged, a spark may be pro-  
duced when you make this connection.  
Use a test light with an incandescent bulb between the ground terminal and the  
power wire to charge these capacitors if this is a concern. The ground wire is the  
most important connection to the amplifier. Make sure it is both electrically and  
mechanically sound.

DPX1800 and DPX11500 stackable configurations  
In this mode, the master amp’s front-panel controls apply to all amplifiers. For ex-  
ample, setting the crossover frequency on the master sets it on all slaves. This works  
for all front-panel controls.  
Multiple amplifiers can be daisy-chained together. For example, if you had six  
DPX1800s in a show car, you could control all of them from one master unit (and one  
remote).  
The following describes the configuration of the amplifiers:  
Master  
Route input from the head into the normal mode inputs.  
Set the master/slave switch to Master.  
Route a single RCA cable from the Slave Out to first slave unit.  
Set the master/slave switch to Slave.  
First slave  
Route a single RCA cable from the master Slave Out to the  
current amplifier’s Slave In.  
Additional slave(s) Set the master/slave switch to Slave.  
Route a single RCA cable from the previous amplifier’s Slave  
Out to the current amplifier’s Slave In.  
Each amplifier can independently control separate speaker loads (assuming the  
phase switch on all amplifiers is set the same).  
Or, to power a large single load (phase switch opposite on the amplifier), you can  
bridge across the amplifiers: + and + to load, - and - to each other. The master amp is  
“speaker +” for in-phase operation.  
Any pair of amplifiers could also be bridged, but be careful to set the phase switches  
correctly.  
Setting the gain  
After completing the installation, follow these steps to set the gain control and perform  
the final system checks.  
1. Turn the gain control all the way down (counterclockwise).  
2. Select the proper input voltage range using the IVS. See “Selecting Input Voltage”  
in the “Operations” section of this manual.  
3. Turn the vehicle’s ignition switch on.  
4. Turn the audio system on with the volume turned all the way down.  
4. Set all tone or equalization controls to flat positions and turn loudness off.  
5. Play a CD and turn the volume up on the head unit until you hear distortion. This  
should be most of the way up.  
APX/DPX Amplifiers  
19  
6. Turn the volume back down slightly.  
7. Slowly increase the gain control (clockwise). Stop when you hear a slight audio  
distortion.  
When the gain is properly set, you should achieve maximum undistorted output with  
the volume turned up all the way, not half way.  
If an oscilloscope is available, monitor the output of the amplifier with the scope,  
watching for clipping of the waveform. Set the gain so that only minor clipping occurs.  
Adjusting the crossover  
The APX2180, APX4360 and DPX2250 amplifiers feature fully-adjustable crossovers.  
The DPX1800 and DPX11500 do not have a way to disable the low-pass 24dB slope  
crossover.  
1. On the APX2180, APX4360, and DPX2250, use the X-Over mode switch to select  
either LP (low pass) or HP (high pass) or OFF for full range.  
2. Using the Frequency (Hz) selection control, select the frequency.  
Setting the bass boost  
1. Initially set the bass boost control to the OFF position.  
2. Listen to a variety of music styles (for example, rock, rap, etc.) and switch the bass  
boost control on until you notice an increase in low bass response.  
Note:  
Using the bass boost requires the amplifier to produce a great deal of  
additional power. Use bass boost sparingly.  
CAUTION  
If you hear a pop caused by speaker overexertion, lower the  
bass boost to prevent damage to the speaker.  
Final system checks  
1. Start the engine and turn on the source unit.  
2. 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 refer to Troubleshooting. Depending on your system, the volume may become  
quite loud even at moderate volume control settings. Until you get an “audio feel”  
for the system’s power, use care when adjusting the controls.  
3. Turn the balance controls to their extreme positions and listen to the results.  
Audio output should match control settings (audio from the left speaker when  
balance is left).  
20  
APX/DPX Amplifiers  
4. Increase the volume and verify that the amplifier reproduces the audio at full  
frequencies without distortion.  
If you hear distortion check the connections and verify that the gain control is set  
correctly. Another cause of distortion could be underpowered or damaged speak-  
ers. Refer to Troubleshooting.

Note:  
The DPX11500 ships with a 200 Amp, ANL-type  
fuse; mount it external to the unit, near the battery.  
Whining noise when engine on  
RCA cables too close to the power wire: Separate RCA and power cables.  
Ground loops are caused by a mismatch in the ground potential (voltage) between  
two sources. Current flows through the shield of the RCA cable and is quickly  
picked up by the amplifier. There are several ways to solve this problem:  
Re-ground the amplifier to a more electrically conductive location.  
Re-ground the head unit to a more electrically conductive location.  
Run a ground wire from the head unit to the amplifier ground.  
Upgrade or replace the ground wire on the battery and alternator.  
Run a ground cable from the negative terminal of the battery to the amplifier.  
Wire the entire audio system using a single connection point to the chassis.  
Induced noise: Relocate components away from electrical noise sources:  
Engine control computers  
ABS brake control modules.

7. Glossary  
Crossover: A device that limits the range of frequencies sent to a speaker or amplifier.  
dB: decibel, a measurement of the relative difference in power or intensity between  
two acoustic signals.  
Equalizer: Component that boosts or cuts sound signal frequencies to improve the  
quality of the sound.  
Gain control: gain is the amount of amplification (voltage, current or power) of an  
audio signal expressed in dB.  
Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle per second.  
IVS: Input Voltage Selector  
Octave: the musical principle of dividing sound frequencies into the eight notes of the  
musical scale.  
Ohm: unit of electric resistance  
PFS: Precise Frequency Selector  
RCA input/output: port through which sound travels in and out of the system; “RCA”  
refers to the type of connector, which was first manufactured by the Radio Corporation  
of America.  
Slope: how fast the sound gets quieter rated in dBs. The higher the dB number, the  
faster the frequency drops off.
