Review: Rockford Fosgate Punch PBR500X1 Amp (video)

 Rockford Fosgate Punch PBR500X1

The new Rockford Fosgate’s PBR500X1 mono amp packs a wallop for such a small design.  It’s literally the size of your hand, and it can drive up to 500 watts RMS into a 1-ohm load, letting you power multiple subs to get more bass.  It has proprietary Boosted Rail (BR) amp technology, which uses capacitors and high-speed circuitry to boost the amp’s power supply voltage when needed.  This way, it can handle massive musical peaks.

With Rockford Fosgate’s PEQ wired remote, you can control the subwoofer impact from your front seat.  The amp also features speaker-level inputs with signal-sensing turn-on, allowing you to connect into almost any system without having to run a turn-on lead back to the receiver.   An extruded aluminum heat sink combines with Rockford Fosgate’s heat management technology for cooling purposes.

“The PBR500X1 Punch amplifier has been designed for systems that require little space,” explained Theresa Hephner, Rockford senior director, products and marketing. “Our patented BRT (Boosted Rail Technology) is an ultra efficient design that doesn’t use a switching power supply to generate its rated power, which allows for a smaller chassis. The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. It’s great for smaller stealth installations, as well as for motorcycles and recreational vehicles.”

We installed this along with the PEQ Equalization remote, and put it through the mill with a wide variety of tunes. The PEQ remote is vital for fine tune adjustments.  The PBR500X1 rocks, and the boosted rail technology gives it that extra power, which rivals much larger and higher-rated amps. It can handle both high level and RCA level inputs,  and it features every adjustment you’d require including “band pass” and “gain” to optimize bass.

The Rockford Fosgate Punch PBR500X1 Amp runs around $350, depending where you purchase, but it is a very good amp for the money, and its size affords it many places to fit…..even a motorcycle.

Check out the specs:
