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 P2502 will bring out extraordinary detail in your music, with ultra-clean power you just can't get from a lesser amp. You get 62.5 watts RMS per channel in stereo mode (plenty for a set of component speakers), or bridge the P2502 for a hefty 250 watts RMS in mono mode (excellent for driving a subwoofer).

It takes more than just muscle to create a prize-winning car audio system. So, the P2502 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.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

Removable Chrome Covers: The Rockford Fosgate Punch P2502 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 P2502 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.

Inputs and Outputs Notes

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 Captive C-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.

Specifications

CEA-2006 Compliance: The specifications given by Rockford Fosgate for the Punch P2502 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.

Best sound ever

Written By lon, clarks hill,in on Thursday, November 20, 2008

I had a rockford fos in my 94 sonoma. It powers TWO TWELVE inch Infinity Subs. And i couldn't ask for a better sound. The bass which is what i went for. And the Rockford Fos is the anwser to my prayers. I hooked up a bigger amp to see if i could get more punch but the smaller RF easily outpowered it.

Great Price for a good amp

Crutchfield Customer Review (What's this?)

I specifically purchased this amp for my single voice coil 8" JBL sub (I bought this many years ago from Crutchfield)that sits in a bandpass box. Not long ago, I bought a wonderful Sony Xplod cdx-F7715x that has 3 preamp outputs. Originally, I had the rear output running my 6x9's and sub in tri way mode using a very old amp that Crutchfield no longer carries (US Acoustics 2080, 80x2. Now that I've purchased the RF amp. I have full control over my speakers, and my sub has NEVER sounded BETTER! Yes, RF amps are up in price, but the sales Crutchfield has are unbeatable! Thanks for everything since 1991.

Thiought it would be more powerful

Crutchfield Customer Review (What's this?)

Installed this amp, and it's bridged to 1 channel had to turn the gain to almost all the way up, I'd say about at 90% just to get some decent bass and volume. I have been installing for about 12 years now professionally at first and now just as a side job, and I have never really been impressed with rockford products, even when the stereo shop I worked at sold them. But I thought i would give the new stuff a try, still dissappointed, when I get the money again i will go with something else and sell this amp. Really dissappointed with the power output, the Stat sheet included says it will produce 397 watts bridged at 4 ohms, but I dont know, seems way less! Rockford always brags about their power, but i have seen much less rated amps and cheaper amps out-perform. For the price you can get better amps for less money!!!!!
