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.

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.

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.

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 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.

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 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.

A
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 ]
A
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 ]
A
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 ]
Q
Does this amp have a regulated power supply (i.e. consistent output potential from 12 - 14 volts)?
[ Brandon  Jan 11, 2018 ]
2 answers
A
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 ]
A
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 ]
Q
Can this amp run two 4 ohm speakers in parallel per channel effectively (so, 4 speakers in total)?
[ Scott  Jul 21, 2017 ]
1 answer
A
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 ]
