About the Rockford Fosgate Punch P4002
Don't let your sound system dance around the ring; fire up a Punch series amplifier from Rockford Fosgate and enjoy a knockout performance every time! These amps will sting your speakers with plenty of clean power, while serving up the sound-shaping controls and high-quality components you need to create a heavyweight audio system.
The innovative circuit design, MOSFET output stages, and proprietary technology inside the Punch P4002 will bring out extraordinary detail in your music, with ultra-clean power you just can't get from a lesser amp. You get 100 watts RMS per channel in stereo mode (plenty for a set of component speakers), or bridge the P4002 for a hefty 400 watts RMS (excellent for driving a subwoofer).
But it takes more than muscle to create a prize-winning car audio system. So, the P4002 sports variable high- and low-pass filters, which help minimize distortion by sending your speakers only the frequencies that they're designed to handle. The Punch bass boost (0-18 dB at 45 Hz) includes a wired remote for hands-on control. You choose the right settings for your car, your speakers, and your ears.

Removable Chrome Covers: The Rockford Fosgate Punch P4002 amplifier features dual removable chrome covers. One of the covers conceals all speaker, signal, remote, power and ground connections, as well as the gain and crossover frequency controls for a cleaner installation.
Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.
MEHSA (Maximum Efficiency Heat Sink Application): 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.
TOPAZ (Tracking Operation Pre-Amplifier Zone): TOPAZ is a circuit that simply eliminates noise. The TOPAZ circuit allows the amplifier ground to move with the source unit ground, creating a "noise elimination" zone just before the preamp section. If there is any noise in the ground coming down the RCA line to the amplifier, TOPAZ amazingly tracks it down and eliminates it. The result is a 30-40dB improvement of the isolation between input ground and chassis ground.
Trans-ANA (TRANSconductance Active Nodal Amplifier): The 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 unit is protected without limiting sound output unless needed.
DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 0% tolerance resistors and large board traces providing greater reliability and efficiency.
TO-247 MOSFET: The Punch P4002 utilizes ultra high performance MOSFET output devices, giving the amplifier more power handling capability as well as lower thermal impedance for more reliable operation, even under the harshest load conditions.
Internal Crossover: The amplifier's internal crossover is a 12dB/octave Butterworth filter selectable for high-pass, all-pass (full range) or low-pass operation variable from 40Hz to 400Hz.
Remote Punch Bass: The Punch Bass helps correct for acoustical deficiencies in the listening environment by helping reproduce full range sound without adding excessive boost. The Punch Bass control has a narrow band adjustment centered at 45Hz, variable from 0dB to +18dB. Using the mounting bracket, the supplied Punch Bass wired remote can be mounted in any convenient location. The module's case can be configured with the bracket above or below the module, or, without the case, mounted flush in your vehicle's dash (requires a 2" x 7/8" cutout with a maximum thickness of 3/8"). The wired remote is 2.281" wide, 1.214" tall and 1.509" deep (2.471" including the knob and cable connection). The included cable is 16.25' in length.
RCA Pass-Thru Jacks: The pass-thru jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. The pass-thru jacks output a full-range signal.
Power Indicator and Protection LEDs: The RF logo, located on the top left of the amplifier, illuminates when the unit is turned on. The "Swirl" portion of the logo illuminates with the output signal level. A yellow "Protect" LED, located next to the RF logo, illuminates if a short circuit or too low of an impedance is detected at the speaker connections. Another yellow LED, labeled "Thermal", illuminates if the amplifier overheats. The amplifier will automatically shut down if either of the two LEDs indicate amplifier trouble.
Power Connections: The power and ground terminals are nickel-plated captive c-clamp wire connectors and will accommodate up to 4-gauge wire. The remote turn-on terminal will accept wire sizes of 12- to 24-gauge. A Phillips-head or slotted screwdriver (not supplied) is required to tighten/loosen the terminals.
Speaker Connections: The 2-channel nickel-plated clamp wire connectors will accept wire sizes of 8- to 18-gauge. A Phillips-head or slotted screwdriver (not supplied) is required to tighten/loosen the terminals.
Remote Punch Bass Connection: An RJ-45 jack is provided for connecting the supplied Remote Punch Bass cable.
CEA-2006 Compliance: The specifications given by Rockford Fosgate for the Punch P4002 amplifier comply with the new CEA-2006 Amplifier Power Standard from the CEA (Consumer Electronics Association). All manufacturers who comply with the standard can display the CEA-2006 logo on their product.
Performance Verification Certificate: Each amplifier comes with a Performance Verification Certificate which lists the results of a 10-point performance inspection as well as a measurement of the actual power output.
