Rockford Fosgate Power Series T400x2ad 2-Channel Amplifier

The Power Series T400x2ad is a 400-watt, 2-channel ultra-compact amplifier built on Rockford Fosgate’s Class-AD technology, delivering constant power across 4- and 2-ohm loads for flexible, space-conscious installs.

• 4/2 Ohm multi-impedance Constant Power: Maintains the same output whether you’re driving 4-ohm or 2-ohm speakers, simplifying wiring choices while preserving performance.
• Rockford Fosgate proprietary Class-AD technology: Delivers efficient power in a compact footprint, ideal for tight under-seat or dash installations without overheating.
• 8 AWG power/ground connector w/ upgraded RCA connectors: Provides robust power delivery and solid signal connections for reliable operation in a mobile environment.
• Remote-Out feature when using high level inputs: Enables turn-on signaling or remote control behavior for other amplifiers when using high-level inputs.
• 4 Ohm bridged capable: Configurable to drive a mono load with a 4-ohm impedance for flexible system designs.
• C.L.E.A.N. input/output clip detection and indicator LEDs: Visual indicators help monitor signal peaks and protect speakers from clipping in real time.
• Top mounted controls: Easy access to built-in crossover settings and tuning without removing the cover.
• Dual fan cooled differential inputs with high level auto turn-on feature: Supports both low- and high-level inputs with automatic turn-on, while active cooling maintains performance.
• Real time thermal sensing and 3-stage thermal lock extrusion with dual fan forced induction: Active cooling and real-time protection keep the amp stable during demanding playback.
• Discrete surface mount technology: Precision construction and compact layout enhance reliability and performance.
• Dual extruded heat sinks: Enhanced cooling capacity to sustain output during long listening sessions.
• 2-Year Warranty: Backed by a two-year warranty for peace of mind.
• 2013 PLC2 remote ready: Compatible with PLC2 remote systems for remote head control.

In a premium car-audio build, the T400x2ad suits space-constrained installations requiring flexible, efficient amplification. Its constant power across impedances, high/low level inputs with auto turn-on, remote-out option, and built-in crossover simplify integration while protecting drivers with clip detection and real-time thermal protection. Dual cooling paths and heat sinks help maintain performance under demanding listening conditions, making it a compact, reliable choice for versatile installations.
