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.

Product Research



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 P300X2 is rated as follows:

  • Power Output:
    • 4Ω: 100 watts x 2-channels
    • 2Ω: 150 watts x 2-channels
    • Bridged: 300 watts x 1-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.


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 crossover has a 12 dB/octave slope. It can be set to high-pass, all-pass (full range), or low-pass operation and the crossover point is variable from 50 Hz to 250 Hz.

Punch EQ: Punch EQ works along 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.


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 50-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 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 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.

Customer Q&A

8 questions already asked

Is it ok to bridge this amp and drive a 2 ohm woofer?
[ Keith  May 14, 2020 ]
4 answers
H Keith, the Rockford Fosgate Punch P300X2 amplifier is a bridgeable amp, but is 4ohm stable in bridged mode. The amp will not be able to power a 2ohm subwoofer when in bridged mode. Please chat with us online or by phone at 1-800-324-9695. We will be happy to assist you with finding an amplifier that would be best suited for your application.
[ Jess  Jun 01, 2020 ]  Staff
Yes I tried it on a low watt 500 rms 10 skar sub at 2 ohms worked well. Amps puts out 412 watts rms at 2 ohm load. According to my build and spec sheet.
[ JAMES  May 29, 2020 ]
This amp is not designed for a 2 ohm single voice coil woofer. It would get very hot and shut down. However, a single voice coil 4 ohm woofer sounds very good on this amp. That's how I'm using it. You can also wire up a dual voice coil - 2 ohms per coil wired in series for a 4 ohm load. Or you could get two 2 ohm or two 4 ohm single voice coil woofers wired in stereo. This amp has a lot of options but one 2 ohm woofer is not one of them. I hope that helps. I will say: this amp says it's only 300 watts, but mine actually delivers over 400 with incredibly low distortion. Happy listening.
[ Scott  May 29, 2020 ]
I think so about bridge
[ joey  May 29, 2020 ]
Best match 12" subs for this amp?
[ Michael  Mar 05, 2020 ]
1 answer
Thanks for your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.
[ Krissy  Apr 02, 2020 ]  Staff
The positive terminal of my left channel won't clamp down hard enough to hold my speaker wire but the rest of the terminals tighten just fine. What can I do to fix this? I'm using 14GA speaker wire by the way.
[ Kyle  Jan 08, 2019 ]

Check to see if the hole (threads) are stripped, if they are you might need to redo the screw hole and possibly use a bigger screw
[ John  Jan 08, 2019 ]
If the warranty is expired then I would suggest you open the amplifier up and take a look. It might be a simple fix. However the technicians at Rockford would be the ideal option. RF has awesome customer support. I apologize for not being able to help you out with your issue.
[ MICHAEL  Jan 08, 2019 ]
I used 8GA with no issues, I would double or triple fold over the end that's being placed inside the terminal to thicken wire
[ Luke  Jan 08, 2019 ]
Does this amp have a regulated power supply (i.e. consistent output potential from 12 - 14 volts)?
[ Brandon  Jan 11, 2018 ]
2 answers
A Crutchfield advisor could better answer this question than me. I do not think it does have a regulated power supply; it is not listed in the information and specifications from Crutchfield.
[ MICHAEL  Jan 17, 2018 ]
Can't produce power without power. It's a great amp for my mids and highs. I supply it with an average 13.8v and it gives me 418 watts of consistent power. I hope this helps.
[ MICHAEL  Jan 17, 2018 ]
Can this amp run two 4 ohm speakers in parallel per channel effectively (so, 4 speakers in total)?
[ Scott  Jul 21, 2017 ]
1 answer
Yes, I run a 4ohm DVC on each channel, which is basically the same thing. It drops the ohm load on each channel to 2 ohms.
[ Jean Paul  Jul 22, 2017 ]
Does it come wit the amp remote?
[ Doug  Mar 05, 2017 ]
5 answers
no remote
[ Chris  Mar 10, 2017 ]
There is no remote control for the amp- it's not needed. The amp turns on when you turn your radio/receiver on using a wire connected to the radio/receiver.
[ Ed  Mar 06, 2017 ]
No remote comes with unit
[ SHAUN  Mar 06, 2017 ]
[ Paul  Mar 06, 2017 ]
[ ROBERT H  Mar 05, 2017 ]
Were is the fuse on a punch p300-1?
[ Wesley  Nov 12, 2016 ]
2 answers
It does not have a replaceable fuse, it must be fused inline. Preferably as close to the battery as is feasible.
[ Jean Paul  Nov 14, 2016 ]
This amp uses an inline 50 amp fuse.
[ LUKE C  Nov 14, 2016 ]
Will this amp be effective for two Rockford Fosgate R25-1x10 speakers?
[ noahliles  Jun 13, 2016 ]
1 answer
It will work, yes. When connecting one woofer per channel, each will get up to 150 watts RMS. I hope that helps. My Bio:
