It's not usually to connect to the amps. It's done like this with a big bus bar at the front, tonnes of runs of power/ground to the back, then another buss bar into a distro block or whatever.
There is resistance in the wire measured per feet that is intself is very small, but when you're a competitor and pulling hundreds if not thousands of amps of current through that wire (Resistance x Current = Voltage) so you'll loose voltage going from the front of the car to the back.
That's why people use large guage wire for large amps, if you use 8ga to power your 2000WRMS amplifier trying to pull that much current through that cable you can loose a volt or two at the amp simply in the wire, amplifiers can die because of lack of input voltage and restrictions in current capabilities.
So these guys, they use 8 runs of 1/0 to reduce the loss of voltage and increase the amount of current that can be transfered, because higher voltage and current means more power to the subs.
Clear as mud?
*EDIT* Here is a picture of someones inside the car

so say 8 runs from bus bar at batt - another bus bar at back with all 8 runs and then 1 run from bus bar to amp.
ok that is cleared up now.

clay is just an acception
