Technologies

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.

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.

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.
