About the Rockford Fosgate Punch P600X4

Buck Pomerantz

Big power for your speakers or subwoofers

Rockford Fosgate's Punch P600X4 amplifier can put out 75 watts RMS to each of your front and rear speakers, plenty of power for clean music even at high levels. You can use the amp's high-pass filter to remove low bass from your speakers so they'll play more efficiently. You can also switch this amp into 2-channel mode to drive a couple of subwoofers with up to 300 watts RMS each. The amp's low-pass filter comes in handy for getting the right sound from your sub/enclosure combo. The Punch EQ2 includes bass and treble boosts, in case you want to add some boom and sizzle back into the mix.

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: first download the setup tones from Rockford Fosgate, then play the tone, 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 will be perfectly set to match your receiver's output. When your receiver reaches maximum clean volume, you'll get maximum clean power from your Power amp. At quiet listening levels, you'll hear less background noise and more of your music.

Keeps an eye on things while playing

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.

Maintaining coolness raises efficiency and lowers distortion

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.

Features

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 P600X4 is rated as follows:

  • Power Output:
    • 4Ω: 75 watts x 4-channels
    • 2Ω: 150 watts x 4-channels
    • Bridged: 300 watts x 2-channel (into 4Ω)
  • Signal to Noise Ratio: 85 dBA (105 dB at rated power)

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.

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.

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.

Controls

Input Level: The front and rear 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 and rear channels. The slope is 12 dB/octave and both can be set to high-pass, all-pass (full range), or low-pass operation. The crossover points are variable from 50 Hz to 250 Hz.

Punch EQ: Both the front and rear amplifier sections have Punch EQ circuits, the function of which 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 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.

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.

Connections

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 100-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 four pair of speaker output 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 front and rear 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 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.

My P600x4 has a Amber light on on the left hand side and blue in middle regardless of what vehicle I have it in or power source going to it and won't play. What is the possible reason?

Has anyone tried using a high level input to this amp? If so how did you like it? Will a loc still be necessary?
gurwinder  Jun 20, 2023

A
The Rockford Fosgate Punch P600X4 does have speaker level inputs Gurwinder, and you will need to use a speaker-level adapter like the JL Audio XD-CLRAIC2-SW in the link below to connect. Using the speaker level-inputs is a great sound, but it will not process the signal from your radio. This can provide great sound and you can always get better sound when using a processor. I hope this helps! https://www.crutchfield.com/p_136XDCLR2S/JL-Audio-XD-CLRAIC2-SW.html

A
It can EZ, as long as you are using 4-ohm speakers. The Rockford Fosgate P600x4 is 2-ohm stable and can support the connection of two 4-ohm speakers per channel. This amp delivers 150-watts into a 2-ohm load, quite a beast!

Yes !! Without a doubt. This amp has more than enough power .
pierre  Apr 06, 2021

I would look into a different head unit if you are losing power to it when you turn up the volume. That has nothing to do with the speaker replacement, however if it has a factory amp it is imperative that the right wires are wired into the new amp. There are schematics that you can download to help...

The Punch 600x4 has plenty of power to run a clean high end system. I am currently running 10 speakers (components and midrange) on the front two channels and two 10" Punch sub woofers on the rear channels which I have bridged @ 2 ohms and the Punch 600x4 does extremely well with clean powerful sound. I do not know what head unit you have, but I wouldn't think it should shut off unless you have a blown speaker/short somewhere in you system. Your head unit may have a cracked board as over time the continuous heating up and cooling down of the circuit board sometimes causes cracks at the solder joints. In terms of the Punch 600x4 satisfying your needs, I think you would not be disappointed and it would also give you options to add more speakers to your system in the future if you choose to. Good luck and happy sounds! Scotty

This will easily get the job done. I'm running a set of JBL 5 1/4" components in the front doors another set of the same in the rear doors and 2 JBL 6x9s in the rear deck and have not had a problem with anything. I pushed this amp a lot last summer driving to the lake for three hours straight with the music loud and it never missed a beat. My old amp would overheat after like 30 minutes in the summer if I was pushing it, but this one has been strong so far. its a great amp and has more than enough power.

In my opinion will the amp work for the subs yes but you wont get enough power out of the amp for those subwoofers. Depending on you ohm load from the subwoofers I would recommend a 2 channel amplifier or a monoblock.

I'm sorry, my system has not been completed yet. Probably another week or so but I will be happy to answer that question when I can. Thanks for the inquiry
greg  Jun 08, 2020

There are 2 things to think about when comparing these 2 amplifier the p600x4 is a little bit cheaper but its not a constant power meaning as you lose voltage and amperage in your vehicles charging system your amplifier loses power (Punch line Amplifiers). Now in the Power series Amplifiers they are constant power and will play at the same RMS power all day as long as you do not go under operating voltage. Hope this helps.
