About the Rockford Fosgate Punch P1000X4D

Heat is the enemy of all amplifiers — sucking power away from your music and damaging internal components over time. Rockford Fosgate came up with some clever innovations that keep these Class D Punch amplifiers running cool, improving efficiency and reducing their size so they can fit in almost any vehicle.

Punch performance
The 4-channel Punch P500X4D amplifier sends 150 watts RMS to each of your front and rear speakers, giving you the crystal-clear power you need to hear the full impact of your music. You can also put the amp into 2-channel mode to drive a couple of subs with 500 watts RMS each. Separate front and rear frequency filters give you razor-sharp control over your speakers' clarity, while the onboard Punch EQ bass boost allows you to reinforce your music's low end when you're using a sub.

Small and cool
This versatile amp utilizes full-range Class D amp technology, drawing much less current from your car's electrical system than traditional amps, running cooler and generating tons of power from a remarkably compact chassis. Rockford Fosgate builds this amp using precision components assembled by high-speed, super-accurate robots — this Discrete Surface Mount system results in less interference between parts, lower operating temperature, and increased life for the amplifier. An amplifier that's built to last, packed with power, and fits almost anywhere — what more could you want for your music?

Features

Overview: The Rockford Fosgate P1000X4D is a 4x150-watt, Class-D, full-range, 4-channel amplifier. Class-D amplifiers are very efficient, which reduces current consumption from the vehicle's charging system.

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 P1000X4D is rated at 150 Watts RMS x 4 channels with an 85dBA signal to noise ratio. The signal to noise ratio at the rated power output is 105dB.

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. It works along with the crossover switch on the amplifier. When the switch is set to Low Pass operation, the Gyrator-based Punch EQ control is a narrow band adjustment variable from 0dB to +18dB at 45Hz that eliminates frequency shift with boost.

Controls

Control Panel: The P1000X4D has top-mounted controls, covered by a removable panel. There are two sets of controls; one set for the front channels and another set for the rear channels. The controls are as follows:

  • Punch EQ: rotary control to adjust the Punch EQ; 0-+18 dB, centered at 45 Hz; operates when Crossover switch is set to Low Pass (LP)
  • Butterworth Crossovers: the 3-way crossover switch lets you select Low Pass (LP), High Pass (HP), or All Pass (AP); the crossover point is continuously variable from 50Hz to 500Hz; the crossover slope is 12dB per octave
  • Gain: rotary gain control; continuously variable from 150mV to 5V (labeled 1 to 11)

2/4 Channel Switch: This side-mounted 2-way switch lets you set the inputs to 2-channel or 4-channel mode. In 2-channel mode, only the front inputs need to be connected to send audio to all four output channels. In the 4-channel mode, both front and rear inputs are connected.

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 8-gauge. The supplied 2mm and 4mm Allen wrenches are required to tighten/loosen the terminals.

Speaker Connections: There are four pairs of speaker outputs for front left/right and for rear left/right. The terminals are nickel-plated set-screw wire connectors and will accept up to 8-gauge wire. The supplied 2mm Allen wrench is required to tighten/loosen the terminals.

RCA Inputs: The 2 pairs of 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.
