Rockford Fosgate TM400X4AD Power Marine 400 Watt Class-ad 4-Channel Amplifier

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.
