Description
Rockford Fosgate Power 400 Watt Class-ad 4-Channel Amplifier
The Power T400X4ad is an ultra-compact, high efficiency 400 Watt 4-channel amplifier. Features multi-impedance Constant Power, input/output clip detection, top mounted controls and dual fan forced induction cooling. Perfect for hybrid, electric, small cars, trucks, motorcycles, and side-by-side UTVs.
The Power T400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgateās 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.
