If you're considering a new car audio system or just want to upgrade your current system, Rockford Fosgate equipment is a solid foundation on which to build. Rockford is one of the oldest and most respected brands in car audio history, and has been pumping out high quality, great-sounding gear since 1973. By pioneering ideas like the Punch EQ (boosting frequencies below 45Hz and above 20Khz for improved in-car music response) and using MOSFET circuitry to power in-car amplifiers, Rockford Fosgate paved the way for modern in-car electronics and hasn't slowed down since.
