Rockford Fosgate Power T400X4 4-Channel Amplifier

Rockford Fosgate's Power Series Amplifiers

Rockford Fosgate is known for producing top-of-the-line mobile audio products. Their Power Series amplifiers are at the top of the amplifier hierarchy, boasting precise audio controls, exceptional durability, and unique technologies for superior and consistent performance compared to other amplifiers currently available in the market.

Dynamic Thermal Management

The Power Series amplifiers utilize Rockford Fosgate's patented "Dynamic Thermal Management," a 3-stage cooling system utilizing forced air to evenly dissipate heat and cool the internal components, resulting in increased efficiency and reduced distortion. The large heatsinks also help with heat dissipation.

MEHSA cooling process

The proprietary process of MEHSA by Rockford Fosgate improves the heat transfer from MOSFET devices to the heatsink, allowing for efficient heat dissipation and cooler transistors.

Extra-quiet inputs

The use of "Differential Input" technology eliminates any electronic interference or hum that may be picked up by the input cables, ensuring only clean signals are processed by the amplifier. This results in a more efficient and quieter music experience, all packaged in a stylish design that is up to 40% smaller than previous models.

T400-4 Power performance

The Power Series T400-4 amplifier delivers 60 watts of RMS power to each of its four channels, providing ample power to drive both front and rear speakers to their maximum potential. This versatile amp can also be bridged to produce 200 watts per channel for a pair of subwoofers, ensuring a robust and pristine audio experience.

Product highlights:
