Element Ready - Amps

These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.

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.

Dust - 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.
Stainless 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.

 

CEA-2006

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.

CE Compliant

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).


 

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 768/2008 EC on 13-8-2008.

The directive gives a detailed description of the initials CE and any other marks specific to a particular directive and the many ways conformity may be acquired.

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 covered in these national regulations are not covered by a pan-European Directive.

Full Range Class-D

A full-range version of the Class-D topology which is a high efficiency amplifier design that reduces current consumption from the charging system.
