The Power T400-4 is a 4-channel amplifier capable of producing 100 Watts into each of its four channels at 2-Ohms. The T400-4 can run a 4-way full-range system or use component speakers on the front with subwoofers on the rear.
Overview
The T400-4 amplifier is perfect for front/rear fading stereo systems or when dedicated amplification is required between front stage speakers and rear subwoofer(s). Thanks to the Dynamic Thermal Management, the small chassis design insures it can be installed in any location – like under front seats.
- 24dB/octave crossover
- 2/4 channel input switch
- MOSFET power supply
- MOSFET output stage
- 4 Gauge power/ground connectors
- Audiophile grade speaker connections
- 2-Year Warranty
Technologies
DTM
Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.
Engineered In The USA
These Avatars are a personal signature from the Rockford Fosgate team member(s) who designed and engineered this fanatic product. This statement illustrates our commitment to being Designed and Engineered in the U.S.A.
NOMAD
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
MEHSA3
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
Punch EQ2
Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.
CEA-2006 Compliant
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
TO-247 MOSFETs
(left-OLD | right-NEW) Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.
TRANS•ana
Trans•ana is a Class A/B topology that simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality.
