Rockford Fosgate T400-4 Power 400 Watt 4-Channel Amplifier

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 – like under front seats. 24dB/octave crossover 2/4 channel input switch MOSFET power supply MOSFET output stage 4 Gauge power/ground connectors Audiophile grade speaker connections.
