Rockford Fosgate T400X2ad 2 Channel 400 Watt Class AD Compact Amplifier

Get a free one-year extended warranty on this select Rockford Fosgate Amplifier when purchased as an Amplifier Installation Kit bundle.



The Power T400X2ad 400 Watt 2-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.
