The Rockford Fosgate T400X4ad 400 Watts Class-AD 4-Channel Amplifier is an ultra-compact, high-efficiency amplifier. It Features multi-impedance Constant Power, input/output clip detection, top-mounted controls and dual fan forced induction cooling. It is 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.

Main Features:

  • Rockford Fosgate proprietary Class AD technology
  • Remote-Out feature when using high-level inputs
  • 4/2 Ohms multi-impedance Constant Power
  • 8 AWG power/ground connector w/ upgraded RCA connectors
  • Differential inputs with high-level auto turn-on feature
  • 2/4 channel input switch
  • Top-mounted controls
  • 4-Ohm bridged capable
  • C.L.E.A.N. input/output clip detection and indicator LEDs
  • Dual fan cooled
  • Dual extruded heat sinks
  • Real-time thermal sensing
  • Discrete surface mount technology
