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 power distribution block near your amplifiers to distribute large gauge power cable to multiple amplifiers.

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 Power and ground wire Speaker wire - 12-16 gauge Grommets (sized to work with the power wire you plan to use in y our installation) Tube of silicone sealant
WIRING
Before beginning, disconnect the negative (-) terminal of the battery prior to connecting the amplifier to the positive (+) 12V terminal to prevent a short to ground and potential damage to wiring and equipment. Some vehicle radios have an anti-theft feature where when the radio is removed from 12V the r adio will no longer function and must be code reset.
7
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. Obser ve 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-on
Po werLock
TM
connector. Loosen the outer screws on the underside of the connector. Insert the speaker leads into the end. Check to be sure you've maintained proper polarity before securing each wire, and plug the
Po werLock
TM
into the
amplifier.
8
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.Drill a pilot hole in the middle of this area.Terminate the ground wire with a ring connector and attach it to the bare metal using a #8 sheet metal screw and washer or preferable, a bolt, nut and a star washer. (not supplied). We suggest crimping and
soldering this connection. After the connection is complete, coat the area (on both sides) with silicone or some
similar material to prevent rust from developing on the bare metal. If your total current draw is over 80 amps (
or total power is over 500 watts
). Keep the ground and power wires as close together as possible, and use the same gauge wire for both.This will ensure that you have a good ground path, and may eliminate such potential problems as engine noise and overheated amplifiers.
CHARGING SYSTEM
If your total current draw is over 100 amps (
or total output power is
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.
9
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

.
CURRENT DRAW
The following is a basic formula to be used as a guide to determine current draw. Your new
DCX
amplifier is more efficient than most other amplifiers.This f ormula is to be used as a guideline.Using wire of a larger gauge can only improve the current transfer of your system. Do NOT use smaller wire gauge.
Total RMS output X 1.5 = Total Input Wattage T
otal Input Wattage
= Current Draw (in Amps)
Supply Voltage
Example:
A DCX
amplifier has two channels at 125 watts per
channel RMS rating into 4 ohms (125X2 = 250 watts). You would use the formula in the following way:
500 W X 1.5 = 750 watts 750W
= 62.5 Amps total current draw
12V
10
If the same amplifier is driven into a 2 ohm stereo or 4 ohm mono load, double it’ s 4 ohm RMS r ating.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 f or 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 ground wire must be the same gauge as the power wire.
11
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
TM
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 secure, the
PowerLock
TM
may be plugged into the amplifier. The
Power/Ground
PowerLock
TM
will accommodate 4 gauge wire for the
DCX 300.2
, and
DCX 500.2
.

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). Plug them into the input jacks, and push in the -12dB input attenuation switch.
ADVANCED INSTRUMENTATION INPUT
The Advanced Instrumentation Input has been incorporated from the legendary
PrecisionPowerTM2500F1
. 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 special cables (see diagram below). This type of input works with any conventional RCA cables.

TC-X CROSSOVER
Your new
DCX
amplifier has a
TC-X
Crossover (Total Control X­over®) 30Hz-4kHz (see this guide for Crossover Chart).12dB per octave phase correlated crossover built-in to provide superior system flexibility without the added expense and installation of an outboard crossover. The speaker outputs of your amplifier are high pass, low pass, or all-pass according to the HP/LP/FULL switch on the front endplate. You would choose low pass (middle position of switch) to use this amplifier for subwoofers, choose high pass (left position of switch), or full (right position of switch) to use this amplifier for full range speakers.
The RCA outputs are controlled by a separate HP/LP/FULL switch, and are always independent of the speaker output crossover. As well as being able to independently select HP/LP/FULL, your new
DCX
amplifier allows independent selection of frequencies from
30Hz-4kHz (see Crossover Detent Chart in this guide).

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).
3. Increase the amplifier gain (clockwise) until the onset of audible distortion. Then decrease the gain to the point just before the distortion starts. This setting minimizes background noise and prevents overload.
4. Repeat step 3 for any remaining independently controlled amplifiers (rear and subwoofer gain controls) in the system.
HIGH MASS INTERNAL HEATSINK
The unique heatsink on your
DCX
amplifier has been designed with fins on the inside of the aluminum extrusion. This allows for the transfer of heat from the circuitry to the heatsink fins and out through the vents in the endplates.Be sure you provide ample space around the amplifier for cooling: at least 2” on all sides.
AP-IV PROTECTION CIRCUIT
Short Circuit Protection engaged: The
DCX
amplifiers will turn off and try to come back on immediately.The amplifier will cycle like this indefinitely with “blips” of sound each time. If this is the case, check your speakers and wiring for low impedance and short circuits. Thermal Protection engaged. The
DCX
amplifiers will turn off and after a minute or so will come back on.In this case, ensure that there is nothing blocking the normal conv ection airflo w of the amplifier. No obstruction should be within 2” of the amplifier on all sides.
Note: Low battery voltage will cause the amplifier to run warmer and possibly damage the amplifier.
