Technologies

• 3-Stage Airflow: 3-stage airflow method effectively exhausts heat and ensures your amplifier runs cooler for optimum performance.
• 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.
• Class-AD: This technology allows the amplifier to produce more power with less current draw from the vehicle's charging system.
• Constant Power: Constant Power is a patented circuit topology that provides instantaneous delivery of output power over varying impedance loads.
• 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.
• 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.
• CE Compliant: This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
• Differential Inputs: Differential inputs eliminate noise picked up by signal cables resulting in clean signal transfer.
