ROCKFORD FOSGATE
ROCKFORD FOSGATE Power 400 Watt Class-ad 4-Channel Amplifier
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.

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