Technologies
MEHSA3
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
CTA-2006 Compliant
Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
Class-BR
Stores energy and dynamically boosts rail voltage to create power on demand.
