Precision Power PCX 250, PCX 280 specification

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-on PowerLock 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 PowerLock into the amplifier.

All two-channel PCX™ amplifiers are capable of being bridged into a 4 ohm mono output without switches or bridging modules. This feature permits the creation of a mono channel for a subwoofer or center channel. Deriving the mono channel is accomplished by using the Left Channel Positive wire (L+) as the positive speaker wire and the Right Channel Negative wire (R-)as the negative speaker wire.

NOTE: It is important that a minimum 4 ohm impedance is observed. If the impedance drops below 4 ohms while the amplifier is wired in the bridged configuration, the amplifier's protection circuitry(AM-IV)may engage.

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 don't worry. Simply add a set of RCAplugs (available at your dealer) to your front or rear set of speaker leads (see drawing below), plug them into the input jacks, and push to the IN the -12dBinput attenuation switch.

The Advanced Instrumentation Input has trickled down from the $15,000 PrecisionPower2500F1. 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 RCAcable.
