The Power T400X2ad is an ultra-compact, 400-Watt 2-channel stereo amplifier built on Rockford Fosgate’s proprietary Class-AD technology platform, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. This design is highly efficient, making it perfect for hybrid, electric, small cars, trucks, motorcycles, and side-by-side UTVs.
Our Constant Power technology, results in up to 25% more output power by balancing demand vs draw. Flexible vehicle integration is achieved via a configurable input harness with Molex style connectivity that accepts both RCA and speaker level signals.
The Power T400X2ad features top mounted controls, allowing easy access to the 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.
Additionally, the T400X2ad has our patented Punch EQ circuit built in and Differential inputs with auto turn-on capabilities.The unit is also compatible with our Punch PLC2 remote level controller (PLC2 sold separately) and is ideal for those installations where you need a compact amplifier that can produce serious high output power.
Top mounted controls allow easy access to the built-in low pass crossover, patented Punch EQ boost circuit and our patented C.L.E.A.N. input/output clip detection circuits
We use "dual fan forced induction" to pull the fresh air in, draw heat off the circuitry and drive it out of the amplifier. This ensures the amp continues to play even under the most demanding musical scenarios
Utilizing Molex style connectors means that installation is easier and quicker than ever before. Literally being able to plug in the amp simplifies the process and allows more reliable connections
