Purchased this Wayne Harris Era Rockford Fosgate Active Crossover for my car stereo some years ago and never got around to installing it. It is complete with 5 pre-programmed frequency cards, 3 DIY blank program cards, original box, packing and owner's manual. A rare "Old School" audiophile quality car audio crossover, like new and fully tested in perfect working order. These were produced when brilliant electronics engineer Wayne Harris, was at the helm of Rockford Fosgate . Thanks for looking!
