Rockford Fosgate T400-4: 4-Channel Car Amplifier

Rockford Fosgate's power series Amplifiers:

Rockford Fosgate has a well-deserved reputation for building high quality mobile audio products.  Their power series amps occupy the top of the amplifier food chain, through fine tuned audio controls, extreme durability, and proprietary technologies that deliver stronger, more reliable performance than most other amplifiers on the market today.

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 "C.L.E.A.N.":

"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 W 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 W each to a pair of subwoofers.  Either way, you can depend on clean, powerful sound from your power series amp.
