My car started to vibrate and when I took it home it started leaking from directly in between my tires and right behind the engine. It seemed to be yellowish brown. Any idea what is leaking?

Might be oil. It would be helpful to know year, engine, and drivetrain.

It's a 2002 Audi a6 3.0 quattro

Whats it feel like on your fingers, smell like, thick or thin, etc.. If it tastes like bad coolant, see what the oil tastes like.

Sometimes it helps to smear a little bit on a piece of white paper to really help determine the color. Really old, or mixed fluids may be hard to determine color.

and where about is it dripping from... if it is coming from about the center of the car under the gear shifterr, then it could easily be output shaft on the center diff.

look under the car, you will see a heat shield just behind the transmission and center diff, if it is wet and dripping chances are the center diff seal is leaking.

I vote for engine coolant coming from the heater box.

But a paper bed pad under the car and see what it shows.
