I don't know too many people in my area that are really into car audio. It'd be nice to find some people to bump with and compare systems. Post up what you got.
As for me, in my 2001 Mazda Tribute:

Front Stage: Hertz HSK 165
Front Stage Amp: running off HU for now
Sub: 2 Diamond D3 12"s in 4 ft^3 @ 34hz
