Rockford Fosgate T400-4, Power Series 4 Channel Car Amplifier
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.
MEHSA3
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
Punch Bass EQ
Pioneered by Jim Fosgate in the early 70's, Punch Bass compensates for acoustical problems common in all cars.
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.
DTM
Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink
NOMAD
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
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.
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.
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.
DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
