CEA-2006 (Amplifier)

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.

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.

MEHSA³

MEHSA³ reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

DSM

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

Engineered in the USA

These Avatars are a personal signature from the Rockford Fosgate team member(s) who designed and engineered this fanatic product. This statement illustrates our commitment to being Designed and Engineered in the U.S.A.
