About: Rockford Fosgate T400X4AD 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 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.

Specifications:

• 4-channel car amplifier
• 100 watts RMS x 4 at 2 to 4 ohms
• 200 watts RMS x 2 bridged output at 4 ohms (4-ohm stable in bridged mode)
• CEA-2006 compliant

Features:

• Class AD amplifier design
• Constant Power technology maintains full output power despite impedance changes
• C.L.E.A.N. gain setup system includes clip lights and test tone CD
• differential input circuitry helps eliminate hum
• dual-fan forced induction cooling
• variable high- and low-pass filters (50-250 Hz, 12 dB/octave)
• variable Punch EQ (bass/treble boost: 0-18 dB at 45 Hz, 0-14 dB at 12,500 Hz)

More Info:

• Preamp and speaker-level inputs (quick-connect input harnesses included)
• Signal-sensing turn-on with speaker-level inputs eliminates need for remote turn-on lead
• 8-gauge power and ground leads and a 60-amp fuse recommended — wiring and hardware not included with amplifier
• No onboard fuses — when installing multiple amps in a system, an additional 60-amp in-line fuse between the distribution block and the amplifier is recommended
• Dimensions (W x H x D): 8-5/8" x 1-5/8" x 4-5/16"
