Rockford Fosgate is a manufacturer of aftermarket and OEM car audio and In-Car Entertainment (ICE) products and accessories, as well as limited Pro Audio, and personal electronics such as earphones. The company was founded by Jim Fosgate in 1973. Fosgate worked from his garage in Arizona, where he pioneered the idea of adding an amplifier formatted for low-impedance loads into cars. These amplifiers were applied to speakers, which in turn made it possible to drown out road and ambient noise that deterred from the music being played.

The company markets currently three distinct product lines with the brand's name. Prime is entry level, Punch line is more in line with other enthusiast level products, and Power represent their high end products.
