Ok, I just upgraded from a powered amp to a mackie profx22 with peavey ipr 3000 power amp. My mains are peavey pr15's unpowered and kustom 12 monitors also unpowered. I am going to have to make use like this till I can afford to upgrade the speakers. Now can I get it to work or am I looking at no monitors? Any suggestions?

One power amp for mains and monitors

Hi.
Now, assuming the cabs are all 8Ohm ones, and the amp is 4Ohm capable, just run the mains parallell from one channel, and the monitors parallell from the other.

Yes they are all 8 ohms. So that would bring it to 4 ohms overall which the amp can handle. now would I just have to make sure that the monitor channel be lower to not mess up the speakers?
Well since most kustom PA gear is junk you will probably blow them up in no time. 
The kustom monitor here.[Invalid or Expired Link Removed] is a 100 watt monitor. You would toast them in no time with an 840 watts a channel amp.

You always have to listen the speakers complaining.
Unless talking about professional PA cabs, the below 100Hz power handling is always a fraction of the advertized.
If in doubt, the less capable cabs can be wired in series, thus reducing the strain on the amp and reducing the probablity of blowin 'em up. Watch Your EQ closely as well.

anyway, yes; set your amp to "stereo", which makes it into basically two totally separate 4Ω amps.
use one side for the two mains and the other side for the two monitors.
each side gets fed with its own signal from the mixing board, ideally through an EQ.

Don't do this.
Use both sides of your amp for the mains, and get another amp for the monitors. Monitors require NO power at all, so it's not like you have to spend a fortune.

I came across a crown crowntech 400 amp for 100 bones. Seems like an older amp, not too much wattage, just not sure on price.
Either use one channel each (Even if your cabs are 4 Ohm, the Peavey IPR series are 2 Ohm capable on both channels) or get second smaller amp for the monitors which will take up more space and add a little more weight (Or a LOT, depending on the amp). The advantage to the second being that you can have 2 seperate monitor mixes if needed.

You'd only toast them if you actually sent that much power to them. As T-Bird wrote, just listen for the speakers complaining and back off if necessary.
No need for another amp at this point. Save your money and apply it toward more capable monitors in the future.
Whatever.
My guess is those speakers will not last a month if you ran 4x the power they are designed to handle.
As an IPR3000 owner, I can assure you that it has volume attenuators and they function quite nicely.
Whatever.
If you are running your monitors that loud then you have other things to worry about.

And it is still possible to get full power even if they are not turned all the way up.
Whatever.
It doesn't matter if the amp is rated to output 100x the handling of the cabs. The OP's volume needs won't change and the chances of blowing cabs is exactly the same as if he was using a 100 watt amp.

You can't limit max output with the attenuators. They are for gain matching.
If he is careful. The good news is after he blows them up he can buy something worth owning.

You may not be familiar with this concept but some people have what they have because it's all they can afford.

Well IME if it is important to you then you will be able to afford it. That kustom monitor I posted a link to earlier cost about $70.00. The average idiot spends more than that on cigarettes,pot and alcohol in a week.
