Rockford Fosgate has been on the cutting edge car audio for decades. Rockford began in Kansas City by a guy named Jim Fosgate back in 1978. They later moved to Tempe, Arizona and became an icon of car audio. Rockford Fosgate has many firsts in car audio including the first ever in car subwoofer, the first in car amplifier, the first to use MOSFET circuitry in audio amplification, the first in car audio processor and finally the fist in car MP3 player. Car audio would not be the same without Rockford Fosgate. Today Rockford still sets standards in car audio amplification, car audio speakers and processing. We have been a Rockford dealer for decades, attended their trainings and stand behind their products. In fact we have even toured the factory and attended RTTI (Rockford Technical training Institute) classes back in the 90’s and early 2000’s.
