Enjoy a demonstration of a first generation Rockford Fosgate Punch 45 and Punch 150 in FULL 1080p! These were originally produced in the late 1980's. In 2005, Rockford re-introduced the Punch 45, 75, 150 and Power 1000 as "25 to Life" anniversary edition models. Rockford, along with Orion, Precision Power, Soundstream, and others help boost the popularity of upgraded car audio systems beginning back in the late 1980's and early 1990's.
The Rockford Fosgate Mosfet series amps eventually transformed into the "HD" or "Hybrid Design" in the early 1990's. Hybrid Design was touted as more efficient an durable because of the surface mounted components. See future videos for more information on the "HD" Series of Rockford Fosgate amplifiers.
