Featuring Constant Power to Produce the Same Output

The Power T400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgates 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.

Fighting Against Your Amp’s Output

Power Series amplifiers actively monitor speaker performance using Rockford Fosgate’s Constant Power technology. A speaker’s impedance naturally fluctuates as it performs, fighting against your amp’s output. So, just like your cruise control increases the engine’s RPM to maintain your car’s speed uphill, Constant Power maintains this amp’s output by increasing its internal voltage and current flow when the speaker’s impedance rises. This results in up to a 25% increase in the amp’s total power output.

Produces More Power With Less Current Draw

Rockford Fosgate uses their proprietary Class AD amplifier technology, combining the high fidelity of a Class A system with the high efficiency of their special Class D technology, to bring you this ultra-efficient, high-output amplifier. In other words, this compact amp produces more power with less current draw from your vehicle’s charging system than most other amps on the road today.
