5 Fuse Requirements You will need to install an in-line fuse or circuit breaker in the powerwire within 18” of the battery. This fuse or circuit breaker is to protectyour vehicle from fire in case the power wire shorts to the vehiclebody. If you are only using one amplifier, use the fuse ratingindic...

AMPLIFIER STATUS LEDS The LEDs provide the following indications: 1. Power - This LED illuminates RED when the amplifier power isturned on with the remote input (output muted). After a short timedelay this LED will turn GREEN (amplifier ready).2. Clip Output - This LED illuminates RED on the peaks o...

Note: The cables running from the battery to the rear of the carshould be installed on the side of the car opposite to the antenna. When using 16 gauge wire or larger, run the speaker wires from theamplifier location through the vehicle to the speakers. Observe thesame precautions for routing these ...

Note: The power connector is inserted into the amplifier withthe wire clamping screws in the up position as shown below.The two negative outputs are common to each other as the twopositive outputs. A speaker may be connected to eitherterminal. GROUND WIRING Locate an area near the amplifier(s) that ...

over 600 watts), you are probably exceeding the capability of yourcharging system. Dimming lights and fluctuating voltage are solidindicators that you need to upgrade your alternator, battery, or both.You should also check the condition and current capacity of thestock battery negative cable and con...

If the same amplifier is driven into a 2 ohm stereo or 4 ohm monoload, 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 curr...

POWERLOCK CONNECTORS Once you have run both the power and ground wires, then connectthe cables to the amplifier. Cut off excess wire, and using wirestrippers, strip the ends of the power and ground cablesapproximately 1/4 inch. Locate the PowerLock TM power and ground connector (supplied). With a sm...

INPUTS There are two sets of RCA jacks on the front end of your amplifier.The RCA cables from your source ...

ADVANCED INSTRUMENTATION INPUT The Advanced Instrumentation Input has been incorporated fromthe legendary PrecisionPower TM 2500F1. This circuit completely isolates the chassis ground from the audio circuit of the amplifierand reduces noise radiated into your signal cables by up to 40dB.This is equi...

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 TM . The two QBASS TM switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers 30Hz, 36Hz, 44Hzand 60Hz. On th...
