Well i have a Phoenix Gold OCTANE-R 8.0:4 amp. Its supposedly 125w x4. My problem is that the speakers i have are 2 ohm, they are KAPPA 60.7CS's. How can i wire these up so they will work correctly?

That amp is only 4 ohm stable in stereo and 4 ohm stable mono.
your only way to go would be to lose adjustment somewhere and wire the speakers at 4 ohm per pair of speakers and wire them to either 2 channels bridged, which would be quite over powered, or 4 ohm stereo and have 2 channels empty

from the specs on the phoinix gold site it is only 4 ohm stable stereo and bridged, I also found the same info on another site as well

Phoenix Gold is LAME!!! I would contact tech suport, or your manual, and find out for sure WHAT the amp is really capable of.
I say PG is lame, because the web page says the Octane-R amps aer 2 ohm stable in stereo, AND 4 ohms stable in stereo... Both stable specs posted on the same page... Someone needs to make up my mind.
Contact Tech support, but a bridged 4 ohm load is the same electrically as is a 2 ohm stereo load, so I would think it would be perfectly safe to run those speakers off that amp. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

While I have no doubt that the amp is indeed 2 ohm stable in 4 channel mode, the power on tap at 2 ohms per channel is probably going to give the speakers a heart attack. End result is sss (smelly speaker syndrome), so if you do this, keep those gains darn near off and watch the volume control.

Nah, those speakers can handle some power. My set is getting a solid 160 watts from my Arc 4150 and I play them pretty hard and I haven't had a single problem. The woofers have a pretty decent heat sink on the back of them. Set the HP xover around 80-100Hz and watch the gains. You'll be fine.
