Ok , so in all my other post i have been using my cell phone but to ask this question i pulled out my laptop to try to use my typing skills.
So , i have seen in some posts here of running in parallel will either get you 16 or 2 ohms depending on how its wired. As well as running in series is a lower ohm load put parallel is a higher load. What im asking is if some one may please lecture me on how these ohm loads work. All i know is that 8Ω+8Ω=4Ω and 4Ω+4Ω=2Ω and 2Ω+2Ω is 1Ω. So like i said if some when can give me a lesson or lecture on how this all works so i can contain more knowledge on amplifiers ad also so i don't fry my amps , Thanks and have a nice day .

Here is a good starting point:

You have it backwards.
In series it adds; it parallel it reduces.

Thanks for the input time to start reading.

So for example If i put my two Peavey 215 in series they are rated 700w program at 4Ohm so it would be a 8Ohm loud and the amp is a Peavey CS 4000hz witch is 800 watts @8Ohms how would that work?

When you series wire, each cab sees only half the voltage. Your amp would have to drive 1400w at 8 ohms to drive them to their "Rated" power.

It's much easier to think about it in terms of voltage than current (watts). I like this calculator to help convert.

1400W at 8 ohms is 105 volts. You'd need a really efficient amp to get that... but 700 watts at 4 ohms is only 52 volts... there are many power amps that can do that easily.

You'd be best to run them on a 2 ohm stable amp which can push 52v at 2 ohms (1400w) or one per channel on one that can do 52v at 4 ohms (700w).

Fine
Since music has a varying dynamic range: the nominal operating level is much lower than peak. While peaks require much more power they are very brief, so the emphasis on large power handing/swing has to be put in the appropriate context of the crest factor and issues like high power non-linearity and thermal compression.
As an implementation philosophy; it is not necessary to drive speakers to full output - especially if it subjects the amp to excessive current.
A conservative approach provides long term durability.
