ROCKFORD FOSGATE T400X4AD 4CH CLASS AD 100RMSX4 CAR AMPLIFIER! PERFORMANCE

The Power T400X4ad is an ultra-compact, high efficiency 400 Watt 4-channel amplifier. Features multi-impedance Constant Power, input/output clip detection, top mounted controls and dual fan forced induction cooling. Perfect for hybrid, electric, small cars, trucks, motorcycles, and side-by-side UTVs.

The Power T400X4ad 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.

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier’s .

Class AD

CE Compliant

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

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

3-Stage Airflow

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

DSM

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