Rockford Fosgate T400-4 400 Watt 4-Channel Amplifier (T4004)

Rockford Fosgate T400-4 400 Watt 4-Channel Amplifier

T400-4 Power performance

The Rockford Fosgate T400-4 amplifier puts out 60 watts RMS into each of its four channels — more than enough to drive your front and rear speakers to their musical peaks. Or you can bridge your T400-4 to blast 200 watts each to a pair of subwoofers. Either way, you can depend on clean, powerful sound from your Power Series amp.

Dynamic Thermal Management

Rockford Fosgate T400-4 Power Series amp use Rockford Fosgate's patented, award-winning "Dynamic Thermal Management," a 3-stage cooling system that uses forced air to dissipate heat evenly across the amp and out through the large heatsinks. This results in cooler internal components, higher efficiency, and lower distortion.

MEHSA cooling process

MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. This allows the heat to escape more readily from the amplifier, so that the transistors stay cooler.

Extra-quiet inputs

Rockford Fosgate T400-4 differential Input circuitry helps eliminate any electronically induced noise or hum that could be picked up by the input cables, allowing only clean signals to enter the amplifier. You get more music with less heat and noise in a stylish package that's up to 40% smaller than previous models.

Cast Aluminum Heatsink

The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

TO-247 MOSFET

The Power Rockford Fosgate T400-4 utilizes ultra high performance MOSFET output devices, giving the amplifier more power handling capability as well as lower thermal impedance for more reliable operation, even under the harshest load conditions.

Power and Protection LEDs

The LEDs are located on top of the amplifier. A blue Power LED illuminates when the amplifier is turned on. A red Thermal LED illuminates if the amplifier overheats. The yellow Protect LED illuminates if a short circuit or too low an impedance is detected at the speaker connections. When any of the protection circuits engage, the amp automatically shuts down until the problem is corrected.
