2, 6x9's with a 12 inch sub woofer. 1 amp to drive the sub and one for the pair. A good EQ up front to help sound balancing. The amps had built in hi-lo pass filters. The stereo amp was a Pioneer @ 90 rms/ 180 max watts, the sub amp was a Kenwood at 100/200 watts. Could be hurtful at full volume.
No front speakers.
If I were to re do it today, I would rethink the lay out to retain the useage of the fold down panel I think. Not that it gets used much.
