CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Following the CEA-2006 criteria, the P1000X1D is rated at 500 Watts RMS x 1 channel with an 80dBA signal to noise ratio. The signal to noise ratio at the rated power output is 100dB.

1-Ohm Stable: The P1000X1D is stable down to 1-ohm. The amplifier is rated at 1,000 Watts RMS x 1 channel into 1 ohm or 2 ohms.

Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 1% tolerance parts and large board traces. DSM improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

Power and Protection LEDs: Power and Protection LEDs are located on top of the amplifier. The Power LED glows red when the amplifier is turned on. The Protect LED illuminates yellow if a short circuit or too low an impedance is detected at the speaker connections. When any of the protection circuits engage, the amp automatically shuts down until the problem is corrected.

Punch EQ2: The Punch EQ on-board equalization circuit helps correct for acoustical deficiencies in the listening environment. This control is a narrow band adjustment variable from 0dB to +18dB at 45Hz with a Gyrator based Punch EQ that eliminates frequency shift with boost.

Infrasonic Filter: This high-pass filter, 24dB/octave, fixed at 20 Hz, is designed to prevent frequencies below the audible range from being applied to the subwoofer. This infrasonic filter improves your subwoofer performance and power handling, particularly in vented enclosures.

Controls

Control Panel: The P1000X1D has top-mounted controls, covered by a removable panel, including the following:

• Punch EQ: rotary control to adjust the Punch EQ; 0-18 dB, centered at 45 Hz
• Internal Crossover: the low-pass crossover point is continuously variable from 50Hz to 500Hz; the crossover slope is 24dB per octave (the low-pass crossover cannot be bypassed)
• Infrasonic Filter: on/off; the crossover point is fixed at 20Hz to 500Hz; the crossover slope is 24dB per octave
• Phase: rotary control; the phase is continuously variable from 0° to 180°
• Gain: rotary gain control; continuously variable from 150mV to 5V (labeled 1 to 11)

Connections

Power Connections: The power and ground terminals are nickel-plated set-screw wire connectors and will accommodate up to 4-gauge wire. An external 100-amp fuse (not included) must be installed on the power wire within 18 inches of the battery. If a wiring kit is used which includes a fuse with a value other than 100-amps, the original should be replaced with a 100-amp fuse. The remote turn-on terminal is also a nickel-plated set-screw and will accept wire up to 10-gauge. The supplied 2mm and 4mm Allen wrenches are required to tighten/loosen the terminals.

Speaker Connections: There are two sets of speaker outputs, internally shorted together, to easily connect two subwoofers. The terminals are nickel-plated set-screw wire connectors and will accept up to 10-gauge wire. The supplied 2mm Allen wrench is required to tighten/loosen the terminals.

RCA Inputs: The RCA input jacks are nickel-plated to resist corrosion.

RCA Outputs: The amplifier also features a pair of Pass-Thru RCA jacks which provide a convenient way to daisy-chain an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the rear amplifier location. The RCA output jacks are nickel-plated to resist corrosion.

Remote Punch EQ (PEQ) Connection: An RJ-45 jack is provided for connecting an optional remote PEQ control (575ROCKPEQ, sold separately).
