You can't make that amp run at 2 ohms with those speakers, you would have to get another set to do that. The speakers are 4 ohms, if you wired the speakers together you could only run them on one channel of that amp to get 2 ohms. Unfortunately you can't bridge those speakers to that amp, it's not stable at 2 ohms in bridged mode. If you haven't used that amp yet you could take it back and get a bigger model. I'm guessing you're trying to get the most out of the amp possible. Just try hooking it up with one Pro-80 on each side of that amp. Kickers are good about producing much more power than stated, so you're probably looking at more like 175X2 at 4 ohms at the end of the day.
Your kicker 4 channel for the cabin speakers is wired correctly. The 2 rear channels on the amp are wired at 2 ohms just to give you an idea what that looks like.
