The PM500X2 is an excellent way to PUNCH up your sound system without
monopolizing your entire trunk - that way you have more room for subs! With its
massive output stage, this amplifier is best suited for driving a pair of 8-ohm
SVC subwoofers or four 2-ohm DVC subwoofers. Remember to utilize the recommended
power and speaker cables to optimize power delivery.
High level input capable with Auto Turn-On circuit
These amplifiers are protected against Dust, UV, Corrosion, and feature
Our Moto-marine amplifiers have not only the capabilities you expect a
Rockford Fosgate amp to have, but we have designed them to stand up to the
environmental conditions you are likely to subject them to. With corrosion
resistant stainless steel hardware and two-part epoxy coated circuit boards,
these units are designed with you in mind. Whether on the lake, on the road or
in the back woods these amplifiers are ready for an adventure.
- We make sure that displays and motor structures are sealed up tight so
they look as clear as possible and perform day in and day out no matter how many
times you hit the trails. UV
Inhibitor Materials - Centrex and ASA plastic materials are used for their
UV radiation resistance and components are tested in accordance with ASTM D4329
testing and certification procedures. Corrosion
Protection (Electronics) – Two part epoxy coated PCB boards prevent
corrosion of critical components due to exposure in moisture rich environments.
Hardware – Stainless hardware is used due to its natural resistance to
corrosion and rusting. This ensures that electrical connections will not degrade
over time due to exposure to the elements.
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.
This product fulfills all essential safety and environmental requirements as

The ce mark is the official marking required by the European Community for
all Electrical and Electronic equipment (and others) that will be sold, or put
into service for the first time, anywhere in the European community.
It proves to the authorities, but also to the buyer -or user- that this product
fulfills all essential safety and environmental requirements as they are defined
in the so-called European Directives.
The ce marking directive (93/68/EEC) was adopted on 07-22-1993 and updated as

In return for fulfilling the CE marking requirements, the manufacturer or its
agent gets the permission to cover the entire European market using only one
approval procedure for the topics covered in the applicable directives.
No member state of the European Community can refuse trade of any (electronic or
electrical) product that has been CE marked (unless fraud suspected). For some
products however, national regulations exist, as long as the requirements

Trans•ana is a Class A/B topology that simplifies the signal path of
the amplifier allowing the signal to travel through the amplifier at a lower
voltage. The result is greater reliability and exceptional sound quality.
An award winning studio quality circuit borrowed from the pro audio company
Hafler. TRANS-ana is a sound quality circuit that is a standard in the recording
industry that simplifies the signal path of the amplifier, allowing the signal
to travel through the amplifier at a low voltage. The result: Greater
reliability, cleaner performance and exceptional musicality, speed, and
Simplifies signal path
Exceptional sound quality
Balanced Differential Inputs
Differential inputs eliminate noise picked up by signal cables.
Differential input circuitry measures the voltage of both the (+) and (-)
input signal. The circuitry subtracts the voltage common to both conductors
(noise) resulting in only the clean signal. This allows only clean signal to
enter the amplifier
DSM utilize 1% tight-tolerances improving efficiency of the circuit,
decreases cross-talk from other discrete components and lowers operating
DSM - An industry-leading manufacturing process, DSM utilizes high-speed
robotics, high-quality 1% tight-tolerance parts and large board traces. The
discrete components are laser etched to meet a particular value and a very low
tolerance. This lower tolerance improves the efficiency of the circuit,
decreases cross-talk from other discrete components and lowers operating
temperature. These superior components are used by aerospace, automotive, and
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases
durability and prolongs the output device life span.
MEHSA3 (Maximum Efficiency Heat Sink Application - gen. 3) is a
proprietary process that yields up to five times better heat transfer than
traditional FET mounting techniques, using the exact same components. A
multi-layer insulated metal substrate operating with minimal thermal resistance
spreads heat both downward & outward to quickly dissipate heat from each device
across the heatsink. This process combined with our optimized heatsink designs,
DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford
Fosgate to squeeze more watts per cubic inch from every output device as well as
provide consistent thermal stability. The 3rd generation creates a dielectric
layer between the ceramic topside and the aluminum base that retains all of the
electrical isolation and capacitive coupling of the original MEHSA material
increasing it's thermal conductivity. The higher power handling results in a 20%
reduction in thermal impedance
NOMAD is a "real time" analog computer that protects your amplifier from
shorting speaker wires and dangerously low speaker impedances.
This circuitry deals with the output stage protection in a Rockford Fosgate
amplifier. You see, we at Rockford Fosgate think a good protection circuit is
one that keeps your amp from going up in flames when the speaker wires touch
together at full power, but won't shut down if the impedance of the load happens
to dive when you are hammering your woofers.
The NOMAD circuit accomplishes just that. It's a totally new and very high
tech method of dealing with device current and voltage parameters, without being
affected by other factors such as heat. Our approach to "real time" protection
is one that uses a mathematical transformation which eliminates the problems
encountered with trying to do real time multiplication of instantaneous device
voltage and current.
Essentially an analog computer calculates at each instant, the maximum
allowable level of safe current for each output device, based on their
instantaneous voltage drop. This allows the protection to be much more precise
than ever before, and ensures reliability.
