SPECIFICATIONS

SUPPORT

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.

CE Compliant

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

C.L.E.A.N. Set-Up

Patented circuit with in/out clip LEDs to help match a source to amp and optimize output.

Constant Power

Constant Power is a patented circuit topology that provides instantaneous delivery of output power over varying impedance loads.

CEA-2006 Compliant

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.

DSM

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

Class AD

This technology allows the amplifier to produce more power with less current draw from the vehicle's charging system.

3-Stage Airflow

3-stage airflow method effectively exhausts heat and ensures your amplifier runs cooler for optimum performance.

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.
