AMPLIFIER STATUS LEDS SHORT PROTECT THERMAL PROTECT POWER CLIP OUT The LEDs provide the following indications: 1. Power - This LED illuminates RED when the amplifier power is turned on with the remote input (output muted). After a short time delay this LED will turn GREEN (amplifier ready). -
Page 8: Tools/Parts For Installation
TOOLS/PARTS FOR INSTALLATION NOTE: TOOLS ARE NOT SUPPLIED. Small flat blade screwdriver Phillips screwdriver (#2 or medium sized) Wire cutters Wire strippers 4 - #6 round head screws, and 1 - #8 sheet metal screw. (or nut, bolt, flat washer, star washer) (see details) 2 - Ring connectors (large enough to accommodate your method of grounding) In-line fuse or circuit breaker... - Page 9 Note: The cables running from the battery to the rear of the car should be installed on the side of the car opposite to the antenna. When using 16 gauge wire or larger, run the speaker wires from the amplifier location through the vehicle to the speakers. Observe the same precautions for routing these wires that you followed for running the power and remote turn on wires.

Page 10: Ground Wiring
Note: The power connector is inserted into the amplifier with the wire clamping screws in the up position as shown below. GROUND WIRING Locate an area near the amplifier(s) that is metal and clean an area about the size of a quarter down to bare metal. Inspect the area around and underneath to be sure you will not drill into wires, brake or fuel lines, etc. -
Page 11: Current Draw
You should also check the condition and current capacity of the stock battery negative cable and connections, and replace or upgrade as necessary. Keep in mind that your amplifiers simply convert electrical energy to acoustical energy, and any electrical deficiency will compromise the performance of your sound system. For more information about charging system upgrades, see you local authorized PrecisionPower Technical Support at 1-800-62POWER x2033 . -
Page 12: Power Wire Size
If the same amplifier is driven into a 2 ohm stereo or 4 ohm mono load, double it’s 4 ohm RMS rating. All DCX amplifiers will effectively double their power at this load. 500W X 1.5 X2 = 1500 watts 1500W = 125 Amps total current draw If you are using more than one amplifier, add up the total current draw for all of them and choose the appropriate gauge based on the... -
Page 13: Powerlock Connectors
POWERLOCK CONNECTORS Once you have run both the power and ground wires, then connect the cables to the amplifier. Cut off excess wire, and using wire strippers, strip the ends of the power and ground cables approximately 1/4 inch. Locate the PowerLock connector (supplied). -

3. QBASS Level Control: Controls bass boost, centered at 40Hz with up to 18dB of boost. 4. Cooling Plenums: Maintain a minimum 2” clearance around cooling plenums for proper amplifier cooling. INPUTS There are two sets of RCA jacks on the front end of your amplifier. The RCA cables from your source unit go in the set labeled INPUTS. -
Page 17: Advanced Instrumentation Input
ADVANCED INSTRUMENTATION INPUT The Advanced Instrumentation Input has been incorporated from the legendary PrecisionPower 2500F1 . This circuit completely isolates the chassis ground from the audio circuit of the amplifier and reduces noise radiated into your signal cables by up to 40dB. This is equivalent to a noise reduction of approximately one hundred times what the noise level would be without this circuitry. -
Page 18: Qbass Plus/Qbass Remote
QBASS PLUS/QBASS REMOTE On DCX 500.1 , DCX 1000.1 , and DCX 1500.1 amplifiers, we’ve taken bass control to a higher level with QBASS PLUS QBASS switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers 30Hz, 36Hz, 44Hz and 60Hz. -

Page 21: Adjusting Input Gain
ADJUSTING INPUT GAIN 1. Adjust all amplifier input gain controls to just above minimum sensitivity (fully counterclockwise). 2. Using the cleanest music source (CD) playing, turn up the head unit source volume until you can hear distortion. Now turn it down a bit until you cannot hear the distortion (usually just below full volume). - Page 22 NO SOUND Is the LED illuminated?
