Rockford Fosgate 400 Watt 4 Channel Bridgeable Class A/B Amplifier Power T400-4

Rockford Fosgate 400 Watt 4 Channel Bridgeable Class A/B Amplifier Power T400-4

The T400-4 amplifier is another super high quality powerhouse from Rockford and 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 cooling system, the small chassis design insures it can be installed in any location - like under front seats. The "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. This is a great compact amp that runs cooler and delivers the legendary Rockford performance you have come to expect.
