Rockford Fosgate built their PM500X1 mono amplifier for marine and powersports applications. If you demand powerful bass while you're blasting along a trail or waterway, this compact amp has all the power you need. And this amp is stable at 1 ohm, so it's great for multi-sub applications.

Made for long life and easy installation

Life on the water or in the dirt can be hard on electronics, so the PM500X1 is built tough. Conformal-coated circuitry withstands moisture and dirt, while the stainless steel hardware won't succumb to corrosion. Rockford Fosgate also uses the newest Maximum Efficiency Heat Sink Application (MEHSA3) construction process, which yields up to five times better heat transfer than traditional mounting techniques. As a result, this amp will rock out without overheating, even when tucked into a compact space.

Level setting made easy

The PM500X1 uses Rockford Fosgate's CLEAN level setting technology, so there's no more guesswork while setting your gain levels. Easy-to-see LED indicators identify clipping so you can set your amp up for maximum performance while eliminating distortion.

Features

Class bd Design: Rockford Fosgate bd topology is a patented design, integrating a technology that is more efficient than typical class A/B amps, and has lower distortion than typical class D designs. Punch bd amplifiers are 75-80% efficient, while class A/B amps are typically less than 50% efficient. This means, more power from your amplifier with less drain on your vehicles electrical and 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 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 150 watts RMS x 1 channel. Additionally the 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.

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.

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 infrasonic filter is fixed at 28 Hz with a slope of 12dB/octave. This high-pass filter is designed to prevent frequencies below the audible 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: To accommodate the varying range of signal levels from today's factory and aftermarket radios, the input level is adjustable from 150mV to 12V.

Crossover: The amplifier's internal low-pass crossover has a 12 dB/octave slope. The crossover point is variable from 50 Hz to 250 Hz. The crossover cannot be bypassed (it's not a full range amp).

Punch EQ: The Punch EQ bass boost circuit is continuously variable from 0 to +18 dB, centered at 45 Hz.

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 80-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. An 80 amp fuse should be placed on the power wire within 18" of the battery.

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

Signal Input: The 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.

Line Level Output: The amplifier has a pair of RCA line level pass-thru outputs to feed another amplifier. The pass-thru output is passive (the same signal present at the amp's input) and the amp's crossover has no effect on the signal.

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.

Note: Previous model PEQ, Punch Bass, and Para-Punch remotes will not work with this amp.
