Technologies

• Element Ready™ | Amps: All components are protected against harsh outdoor elements like Dust, UV, Temperature, Water, Corrosion & Vibration.
• 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.
• 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.
• P.O.W.E.R.: Power supply circuit design that allows the amplifier to increase output power as voltage increases.
• C.L.E.A.N. Technology: C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to amp and optimize output.
• Balanced Differential Inputs: Differential inputs eliminate noise picked up by signal cables.
• MEHSA 4 (Maximum Efficiency Heat Sink Application): MEHSA⁴ reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
• NOMAD: NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
• CE Compliant: This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
