Rockford Fosgate 4-channel ultra-compact amplifier

 

The Power TM400X4AD is a 400-watt 4-channel amplifier that utilises Rockford Fosgate’s advanced Class-AD technology, delivering consistent power output across both 4-Ohm and 2-Ohm loads thanks to its Constant Power design. Engineered for flexibility and durability, it’s ideal for marine or vehicle installations, with both high- and low-level inputs and an auto turn-on feature. Top-mounted controls provide quick access to the built-in crossover and C.L.E.A.N. input/output clip detection circuits. With dual fan cooling, robust thermal protection, and a compact footprint, this amp is powerful, efficient, and built to last.

  • Class-AD technology with Constant Power for consistent output at 4-Ohm and 2-Ohm
  • 4-channel amplifier, bridgeable at 4-Ohm
  • High- and low-level differential inputs with auto turn-on
  • C.L.E.A.N. input/output clip detection and indicator LEDs
  • Top-mounted controls for easy setup and tuning
  • Dual fan cooled with 3-stage thermal lock extrusion for heat management
  • Real-time thermal sensing and protection systems
  • 2/4 channel input switch for installation flexibility
  • 8 AWG power/ground terminals and upgraded RCA connectors
  • Remote-Out feature when using high-level inputs
  • Discrete surface mount components for enhanced reliability
  • Marine-grade epoxy coating on circuit boards for environmental resistance
  • 2-year manufacturer’s warranty
