Rockford Fosgate Punch P400-4

Rockford Fosgate continues to develop progressive sound technologies. Their aim — to produce a smaller amplifier, with all the power and clarity you expect from the Punch name. The award-winning "Dynamic Thermal Management" 3-stage cooling system uses forced air to dissipate heat evenly across the amp and out through the heatsink. The internal components in these compact amps stay cooler, resulting in higher efficiency and lower distortion. You get more installation options, without sacrificing wattage or audio quality. 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. The P400-4 4-channel amp dispenses 50 RMS watts per channel to your front and rear speakers, or you can bridge it for 200 watts RMS into two channels for your subs. You can tailor the sound with variable-frequency high- and low-pass filters, and use the onboard EQ to add ...
