My friend used to have a set of those back in highschool in the late 90s... yes they came from full-range preloaded Kicker boxes that also had two 2" x 6" horns. They're rated at 4 ohms each btw, handles a wee bit less power than Kicker Comps but has a smoother midrange response since it was running full-range. They were in a ported box, the port was 2 1/2" in diameter and 9 inches long and I think they had like 1.5 cf each.
I do remember that it sounded pretty good in the 88 grand Am two door bumping 2Pac's California Love, the girls in our highschool were all like "ohhh bass!" and we were using the factory stereo to run it haha.
