Quick Review:

Rockford Fosgate continues to deliver innovative sound technology with amplifiers such as the Rockford Fosgate Punch P400-4. This car amplifier features an award winning Dynamic Thermal Management which uses a uniquely designed heatsink to effectively cool and dissipate heat evenly. This allows the internal components of the amp to stay cooler and therefore increase efficiency and limit the amount of distortion. Performance is high as well with the Rockford Fosgate Punch P400-4 4 channel amplifier, producing a 50 watt RMS x 4 channel rating at 4 ohms (100 watts x 4 at 2 ohms). And keeping with the standards in the industry, you can customize the sound output with both high and low pass filters.
