Features

5-Channel Design: The Rockford Fosgate PM1000X5 is made up of three sections, two full range stereo amps (front and rear) and a mono subwoofer amp. The full range amps are Class-AB and the subwoofer amp is Class-bd, a patented, more efficient design. The front and rear amps are independently bridgeable, meaning the PM1000X5 can be used as a 5-channel, 4-channel, or 3-channel amp. The minimum impedance for the full range amps is 2Ω (4Ω when bridged) and the minimum subwoofer amp impedance is 1Ω.

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 4Ω load with 1% or less Total Harmonic Distortion plus noise (THD+N). CEA-2006 allows consumers to compare amplifiers and receivers under identical conditions. The CEA-2006-rated RMS power output is 75 watts RMS x 4 channels (full range) plus 150 watts RMS x 1 channel. Additionally the full range power output is 125 watts RMS x 4 channels into 2Ω and 250 watts RMS x 2 channels bridged (into 4Ω). The subwoofer power output is 300 watts RMS x 1 channel into 2Ω and 500 watts RMS x 1 channel into 1Ω.

Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. Casting improves cooling efficiency approximately 30% over conventional extruded heatsink designs.

Dynamic Thermal Management (DTM): DTM evenly distributes excess heat across the amplifier's entire heatsink.

MEHSA³ (Maximum Efficiency Heat Sink Application-3rd Generation): MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA substrate operates with minimal thermal resistance, spreading heat both downward and outward to quickly dissipate heat from each device across the heatsink. This allows greater power output, enhanced thermal stability, and maximum reliability.

Trans-ANA (TRANSconductance Active Nodal Amplifier): Trans-ANA is a circuit that allows the audio signal to pass through the amplifier at low voltage. The signal is directly level-shifted to the fixed high voltage rails via a pair of drive transistors. Signal linearity is assured by an active node formed by the drive transistors at ultrasonic frequencies. The result is crystal clear sound quality.

NOMAD (NOn-Multiplying Advanced Decision): NOMAD is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The amplifier is protected without limiting sound output unless needed.

DSM (Discrete Surface Mount): High speed robotics are used in the manufacturing process 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.

CLEAN Set-Up: Rockford's integrated level setting technology, CLEAN (Calibrated Level Eliminates Audible Noise), replaces sophisticated test equipment with input/output clip LEDs, allowing you to match the source unit's output to the amp's gain, and optimize the amp's output. The input clip indicator works in conjunction with the audio source volume, illuminating red when the source reaches it's clipping point. The output clip indicator works in conjunction with the input level dial on the amp, illuminating the appropriate color depending on the audio content used for the setup.

Balanced Differential Inputs: Differential inputs eliminate noise picked up by signal cables by measuring the voltage of both the (+) and (-) input signal, then subtracting the voltage common to both conductors (noise), resulting in only the clean signal entering the amplifier.

Infrasonic Filter: The subwoofer section's infrasonic filter is fixed at 28 Hz with a slope of 12dB/octave. This high-pass filter is designed to prevent frequencies below the audio range from being applied to the subwoofer, or reproduced by the amplifier. This improves your subwoofer performance and power handling, particularly in vented enclosures.

Controls

Input Level: The front, rear, and subwoofer sections of the amplifier have separate input level controls. To accommodate the varying range of signal levels from today's factory and aftermarket radios, the input levels are adjustable from 150mV to 12V.

Crossover: The amplifier's internal crossovers are also independent for the front, rear, and subwoofer channels. The slope of all three is 12 dB/octave and the crossover points are variable from 50 Hz to 250 Hz. The full range sections can be set to high-pass, all-pass (full range), or low-pass operation. The low-pass crossover in the subwoofer section cannot be bypassed.

Punch EQ: Each amplifier section has its own Punch EQ circuit. In the full range amps, the EQ function changes with the crossover switch. When the crossover is set to low-pass, the Punch EQ acts as a variable bass boost; 0-18 dB at 45 Hz. When the crossover is set to high-pass, the Punch EQ acts as a variable treble boost, 0-14 dB at 12.5 kHz. When the crossover is set to all-pass, both the bass and treble boost circuits are active. The subwoofer amp has only the bass boost; 0-18 dB at 45 Hz.

Input Switch: With the input switch in the 2-channel position, connecting only the front inputs will send the signal to both the front and rear sections of the amplifier. In the 4-channel position, both front and rear inputs must be used.

Sub Input: If the source unit has a dedicated subwoofer output, set this switch to On to activate the amplifier's sub input.

Remote Punch Level: When activated, this switch allows the use of a optional remote Punch Level Controller (PLC2).

Infrasonic Filter: A switch allows you to turn the infrasonic filter off if you prefer.

Connections

Power Connections: The power and ground terminals are captive c-clamp wire connectors and will accommodate up to 4-gauge wire. An external 150-amp fuse (not included) must be installed on the power wire. The remote turn-on terminal will accept up to 14-gauge wire. A Phillips head screwdriver (not supplied) is required to tighten/loosen the terminals.

Fuse: The amplifier does not have an on-board fuse. A 150 amp fuse should be placed on the power wire within 18" of the battery.

Speaker Connections: The six pair of speaker output terminals (front left and right, rear left and right, and two subwoofer outputs) are also captive c-clamps and will accept up to 8-gauge wire. The two subwoofer outputs are internally wired in parallel, making it easy to connect two subs. A Phillips head screwdriver (not supplied) is required to tighten/loosen the terminals.

Signal Input: The front, rear, and subwoofer RCA inputs will accept either a line-level or speaker-level input. A speaker-level signal can be connected using a Speaker Wire to RCA adapter (sold separately). When using a speaker-level input signal, the auto turn-on feature is active and the remote turn-on terminal becomes a 12 volt output to turn on/off an additional amplifier or other component.

Punch Level Control (PLC): An RJ-45 jack is provided for connecting an optional wired remote PLC2 (item number 575PLC2, sold separately), allowing remote control of the output level of the amplifier. A second RJ-45 jack is the PLC output, used to daisy-chain additional amplifiers controlled by a single remote.
