So if you have 2 8ohm cabs, the load will be 4ohms. Is that the same in series and parallel or does it change?

if you're doing exactly as jaymel's rig, you're describing "series" operation.
FYI,
when the head has a mono power amp, i.e. a single power section, alot of manufacturers say that the pair of outputs from that head are in "parallel", which IMHO, is a bit of a misnomer. so, if you connect two 8 ohm cabs directly to the pair of outputs right on the amp, then you'll be drawing a 4 ohm load from the head's power section. e.g. an Aguilar DB750.
but if the head has stereo power amp, i.e. two power sections with one output each section, then the amp load for each 8 ohm cab would be 8 ohms each, since they're getting their own power section. this is figuartively described as "parallel" operation. e.g. an Eden WT800.
and in the same way, if you daisy chain both cabs ("series") to only one side or power section of the stereo head, that one side will be pulling a 4 ohm load, as if it was a mere mono head like the example above.
make sense?
"Daisy chaining" is NOT the same as series connection. It may have the illusion of series because you are connecting the cabs "one after the other," but electrically they are in parallel. You're just paralleling them at a different point in the circuit.
As far as I know, the only mass produced major brand that has ever done anything different with their output connectors is the Eden Nemesis series (perhaps only the older versions), where they made it so when you plugged in an extension speaker, it ended up in series with the internal combo's driver. The idea being that normally you'd want to deliver maximum rated power to the internal speaker, and always avoid going below the minimum impedance rating for the amp when running more speakers.
Some anal-purists (sometimes even myself) prefer to run the speaker cables individually from the separate jacks on the amp head. This making the distance the electrons travel to each cabinet the same (with equal length cable), unlike when you daisy chain, the speaker farthest away gets the signal an infinitessimal amount of time later (could throw off your timing... ha-ha!).
By the way, for Americans unfamiliar with the (Brit-Euro)terminology (no offense to any parties), "jacks" = 1/4" phone connectors of either gender. To Americanskis, "jack" signifies a female connector of varying types (1/4", XLR, RCA, etc.). "Jack-plug" = 1/4" male, "jack-socket" = 1/4" female. I know, I know, TMI...
