Rockford Fosgate continues to develop progressive sound technologies. Their aim to produce a smaller amplifier, with all the power and clarity you expect from a Punch amp.

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.

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 some high- and low-frequency punch to compensate for your car's acoustics. An optional wired remote control lets you tweak the sound from the front seat for quick adjustments while you're on the road.
