PROP 65 WARNING
The TM400X4ad is a 400 Watt 4-channel amplifier with high efficiency Class-ad technology and a conformal coated pc board designed for motorsport and marine applications.
This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).% efficiency ratings vs. 20-60% efficiency ratings of traditional class A/B amplifiers.
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.
Element Ready™ - Amps
These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.
This technology allows the amplifier to produce more power with less current draw from the vehicle's charging system.
Constant Power is a patented circuit topology that provides instantaneous delivery of output power over varying impedance loads.
The Power TM400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.
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.
3-stage airflow method effectively exhausts heat and ensures your amplifier runs cooler for optimum performance.
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
