Fuse Requirements You will need to install an in-line fuse or circuit breaker in the power wire within 18” of the battery. This fuse or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body. If you are only using one amplifier, use the fuse rating indicated in this chart. If you are using more than one amplifier, add up the fuse ratings for all the amplifiers. This sum is the rating for your fuse or circuit breaker. You may also want to add a powe

AMPLIFIER STATUS LEDS 3 4 SHORT PROTECT THERMAL PROTECT POWER CLIP OUT 1 2 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). 2. Clip Output - This LED illuminates RED on the peaks of the output signal when the peaks are too high. This clipping causes audible distortion in the speakers. 3. Short - This LED illuminates RED on

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. Cut off excess and, using wire strippers, strip 1/4-inch of insulation. Locate the speaker/remote turn- TM on PowerLock conne

Note: The power connector is inserted into the amplifier with the wire clamping screws in the up position as shown below. The two negative outputs are common to each other as the two positive outputs. A speaker may be connected to either terminal. 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. Drill a pilot

over 600 watts), you are probably exceeding the capability of your charging system. Dimming lights and fluctuating voltage are solid indicators that you need to upgrade your alternator, battery, or both. 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 performanc

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 12V 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 grand total. POWER WIRE SIZE A minimum of 8 gauge or a maximum of 4 gauge wire is recommended dependent on the application. The

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 TM approximately 1/4 inch. Locate the PowerLock power and ground connector (supplied). With a small flat blade screwdriver, loosen the screws before attempting to insert the cable wires. Insert the wires into the appropriate hole, and tighten the screws. Once the wires are TM secure, the Pow

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. If your source unit doesn’t have RCA outputs, then add a set of RCA plugs (available at your dealer) to your front or rear set of speaker leads (see drawing below

ADVANCED INSTRUMENTATION INPUT The Advanced Instrumentation Input has been incorporated from TM 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. It provides all the benefits of a true balanced line without the need of any spe

QBASS PLUS/QBASS REMOTE On DCX 500.1, DCX 1000.1, and DCX 1500.1 amplifiers, we’ve TM taken bass control to a higher level with QBASS PLUS . The two TM 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 TM and 60Hz. On the rear end plate you will find the QBASS level TM control and plug-in for an optional QBASS REMOTE dash mounted level control.
