Quick Review:

Rockford Fosgate continues to deliver innovative sound technology with amplifiers such as the Rockford Fosgate Punch T400-4 4 channel amp. 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. Another feature that is distinct to the Power Series amplifiers is what's called “differential input”. What this does it eliminates any kind of cross over or leakage of electronically induced noise such as a ‘hum'. The Rockford Fosgate Power T400-4 is yet another great example of a fine tuned amplifier that parallels the reputation Rockford Fosgate has established.
