Rockford Fosgate T400-4 4-Channel Car Amplifier


Rockford Fosgate enjoys a well-deserved reputation for building high-quality mobile audio products. Their Power Series amps sit at the top of the car audio food chain, with proven durability and proprietary technologies that deliver stronger, more reliable performance than most other amps on the planet today.

Serial Numbers Are Recorded and Photographed Per Each Customer Order. Any product returned for any reason Must be returned in its original and serial number matching box / packaging.

Dynamic Thermal Management

Power Series amps 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

"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.

T400-4 Power performance

The 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.
