Description
Rockford Fosgate Power 400 Watt 4-Channel Amplifier
The Power T400-4 is a 4-channel amplifier capable of producing 100 Watts into each of its four channels at 2-Ohms. The T400-4 can run a 4-way full-range system or use component speakers on the front with subwoofers on the rear.
The T400-4 amplifier 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, the small chassis design insures it can be installed in any location ā like under front seats.
