Does anyone know if the head unit powers the six speakers and a separate amp power the sub or is there a factory amp separate the head unit that powers all the speakers? If it just powers the sub, do you think it could push an 8" in a ported box?

The factory radio is made by clarion and powers the front and rears only. The factory sub has it's own tiny amp. It can only be used with the factory speaker because it is rated at 1ohm. Any higher speaker eg. 4ohm, the amp will produce almost zero volume.
Figure: cd player-40x4 (more or less)
tiny factory amp-20x1
Total-180watts

Hey Leo...what do you mean by getting another 100-150watt amp?!? Were you talking about running that to the factory sub?!?

The factory sub is only 80w max.. you can't hook a 100w amp to it. Now getting an additional sub and amp would be the best idea.
