Rockford Fosgate's Punch P500X1bd subwoofer amp can produce up to 500 watts RMS, giving you plenty of clean power for your rhythm track. And the P500X1bd can drive a 1-ohm load, so you can power multiple subs without any trouble. A low-pass filter keeps the high notes away from your sub, while a subsonic filter helps you rein in runaway boom. The Punch bass boost lets you add some of that boom back into the mix when it's needed.

Once again, Rockford Fosgate steps away from the crowd with their C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) — a setup system that ensures your music will sound as clean and powerful as possible. It works like this: play the setup tone on the included test CD, adjust the receiver volume until a red clip light on the amp goes out, then turn the amp gain up until a blue light comes on. It's that simple — your amplifier is now set to match your receiver's output. When your receiver reaches maximum clean volume, you'll get maximum clean power from your Punch amp. At quiet listening levels, you'll hear less background noise and more of your music.
If that blue light turns solid red while you're playing music, the amp's telling you that your source is distorting and you should turn it down, or risk damage to your gear. The optional PLC2 remote level control also doubles as a clip indicator, so you can see from the front seat if your music's clipping. The amp's built-in computer keeps tabs on the output current, ensuring that plunging speaker impedances (they change during play) or even a short circuit won't hurt anything.
Rockford Fosgate's Dynamic Thermal Management system uses forced air to dissipate heat evenly across the amp and out through the high-mass heatsink, efficiently drawing heat away from vital internal parts. Their proprietary MEHSA cooling process maximizes the heat transfer from the MOSFET devices to the heatsink, allowing the heat to escape more readily, so the transistors stay cooler and work better.

Average Customer Review(s):
great amp plenty of punch
Pros: great amp
Cons: none yet
I have this amp pushing 2 p3's along with a pair of RF 4way 6x9's in the rear and a pair of RF 2way 5 1/2's up front with RF prime 250x4 pushing the inside, let me just say....my neighbors aint happy. Turn it up and it's all is crisp and clear. Good power from both amps!??
Pros: Great Power, solid amp!
Cons: None for me.
Very impressed with this amp. Has plenty of power starting to think I should of went with 2 12s instead of 10s. Very easy to set up too.
Rockford fosgate products never disappoint,,
This is a super powerful amp!! My birth sheet is almost doubled its stated RMS power. 308 watts @ 4ohms, 525 watts @ 2ohms and 810 watts @ 1ohm. I have two Rockford fosgate p3sd4-10 subwoofers, I haven't gotten it all hooked up yet, but I can tell these subwoofers are going to be thumping!!!! Great amp. Recommend it to anyone looking for good power but not wanting to spend a whole lot.
Pros: Lots of power, semi compact, great reliability, looks stealthy.
Good clean solid sound paired with 2 Rockford Fosgate P3SD4-12

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 measuring 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 with 1% or less Total Harmonic Distortion plus noise (THD+N) over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Rockford Fosgate P500X1bd is rated as follows:
Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% cooling improvement over conventional extrusion 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.
Power and Protection LEDs: The LEDs are located on top of the amplifier. A blue Power LED illuminates when the amplifier is turned on. A red Thermal LED illuminates if the amplifier overheats. The yellow Protect LED illuminates 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.
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 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.
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.
Power Connections: The power and ground terminals are nickel-plated 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 12-gauge wire. A Phillips or flat-head screwdriver (not supplied) is required to tighten/loosen the terminals.
Speaker Connections: The two speaker outputs are internally wired in parallel, making it easy to connect two subwoofers. The speaker terminals are also nickel-plated captive c-clamps and will accept up to 8-gauge wire. A Phillips or flat-head screwdriver (not supplied) is required to tighten/loosen the terminals.
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 up to two additional amplifiers or other components.
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 number575PLC2, 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.
