i have seen amps that advratize power a lit higher at 2 ohms but most or all speakers i have looked at are 4 ohm how does this work? does this have somthing to do with the way they are wiried? or are there diffrent speakers?

These are resistance valued which need to be considered when installing speakers. If the amplifier is rated for a 4 ohm output, it could damage speakers rated at 2 ohms or damage itself. A stereo rated at 2 ohm output may not drive 4 ohm speakers very well. Two 4 ohm speakers in parallel will "look" like a 2 ohm load to the stereo.
The most common is 4 ohm. You can wire either to have the proper resistance value. Wiring speakers in series doubles the rated value, wiring them in parallel cuts the rating in half. But it is much easier to just buy the proper speakers.
SOMETIMES, if you use many speakers, you will have to do the wiring to make them correct for the stereo. An example: Two 4 ohm speakers in series = 8 ohms. Do the same thing with two more, then put the first two in parallel with the second two and we are back at 4 ohms. Your 4 ohm stereo could now drive 4 speakers where 2 would usually go (like 2 on the front output wires).

its the independence of the speaker the 2 ohm has less resistance than the 4ohm

Go to about the middle of this site and you will see different wiring methods of subwoofers to get different impedances (resistance values, ohms):

The impedance. You want to match the speakers to the output transformers or semi conductors.

2 OHM's...Man that was an easy question.
