English 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.
English 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.
English 5. INSTALLATION AND WIRING 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 authorized Clarion Dealer for installation recommendations. • This unit is exclusively for vehicles with a negative ground, 12V power supply.
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.
English 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.

Mono subwoofer system (APX2180 and APX4360) In this application, the rear channels are bridged for mono operation to drive a subwoofer while the front channels are available to drive a set of full-range speakers.
English Two-channel full-range or subwoofer system (APX2180) In this application, the APX2180 is used to drive two speakers.
- LEFT + - + - RIGHT + REM GND +12V English Four-channel high-power system (APX4360) In this application, the APX4360 is used as a four-channel amplifier to drive four speakers in stereo with fader control.
English 2-Ohm subwoofer system (DPX1800/DPX11500) This application shows a DPX1800 or DPX11500 driving a pair of DVC 4Ohm subwoofers. DVC 4 Ohm subwoofer DVC 4 Ohm subwoofer DPX1800/DPX11500 speaker configurations Although the units produce maximum power when connected to a 1 or 2 Ohm load, a 2-Ohm load is recommended. WARNING Do not connect a load less than 1-Ohm as permanent damage may occur and the warranty will be nullified. The following DPX1800 or DPX11500 configurations achieve full power.
In this mode, the master amp’s front-panel controls apply to all amplifiers. For example, 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.
English 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.
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 speakers. Refer to Troubleshooting. 6. Troubleshooting Indicator lights The APX2180, APX4360, DPX1800 and DPX11500 have lights that indicate amplifier status.
English Amplifier shuts down after playing for a period of time • Thermal protection circuits are shutting the amplifier off: Check the location for adequate ventilation. Relocate amplifier as required. Consult an authorized Clarion audio dealer. Distorted audio • Gain is not properly set properly: review the instructions for setting the gain. • Speaker cones are damaged: inspect each speaker cone for signs of damage, such as a frozen cone, burnt smell, separated or ripped surround or separated spider.
English Ticking noise when engine on • High voltage ignition problem: Check for problems with the ignition system and replace components as required. • Cracked distributor caps • Carbon traces on plug wires • Loose spark plugs 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.
