Basically, all it does is let you know how much power you'll get out of your amp.
There isn't a certain time to use a 4ohm speakers.....other than when you want to get the amount of power out of your amp that it puts out at 4ohm. But one impedence isn't inherently better than any other.

You'll find that amplifiers produce more power when hooked up to a low resistance load.
Example 4ohm=100Watts, 2ohm=200Watts, 1ohm=400Watts.
Secondly some amps can't run at a 2ohm or 1ohm load and will become unstable.
You need to look at the speakers you want to use, the wattage you need to drive them, and the amp which will give you that power at the resistance the speakers are at.
Typically your front stage speakers run at 4ohm in stereo. Simply match with a 2 channel amp with the correct power rating at 4ohm.
The sub stage depending on how you set it up can run from 8ohm to 0.5ohm. The resistance depends on the number of speakers and how you wire them. Most people pick the speakers they want, wire them in parallel to drop the resistance to 2 or 1ohm and then decide on an amp.
