Rockford Fosgate Punch PBR500x1

Mono Block Amplifier


The Rockford Fosgate Punch PBR500x1 Mono Block amplifier with a 500 Watts RMS with Boosted Rail Technology, allowing it to be compact and efficient while providing big power.

This amp is great for smaller stealth installations, motorcycles and recreational vehicles.

  • 12dB/octave Butterworth crossover
  • MOSFET output stage
  • High level inputs
  • Ultra compact chassis
  • Variable 4-6 volt hi level DC offset voltage input turn-on control
The Rockford Fosgate Punch PBR500x1 Mono Block Amplifier uses our patented BRT (Boosted Rail Technology) for an ultra efficient design that does not use a switching power supply to generate its rated power.
This allows the chassis design to be much smaller than traditional sized amplifiers. The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system.
It is great for smaller stealth installations, as well as for motorcycles and recreational vehicles.
* 1 Year Warranty as per Rockford Fosgate Australia



CEA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier’s output power ratings are REAL POWER numbers, not inflated marketing ratings.

Read CEA-2006 Amplifier Power Standards under Answer ID #199 in our Knowledge Base.




U.S. Patent US 8,212,620 B2

Stores energy and dynamically boosts rail voltage to create power on demand.

To achieve higher efficiency with lower distortion, Rockford Fosgate’s BR topology combines, cycle-by-cycle, an indirectly coupled high/low voltage rail linear topology. This combination yields an unsurpassed power density (watts per cubic inch).






Punch EQ2

U.S. Patent 3,883,832

Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.

In the early 70’s, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars:

  • A midbass hump between 100-275Hz
  • A steep roll-off of high frequencies from 2kHz up to 20kHz
  • Reduced bass response below 50Hz

The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.
