Sure, it's nothing crazy. How I have it wired is I have the PS for the amps running directly to a high current power conditioner. Then I cut the end off that and wired it to an IEC Male connector which is attached to the back of the cab so you can run a regular computer plug to it. Same thing with the other PS. So each PS has its own line out of the cab. This allows me to plug in the cab into separate circuits in the house. (i.e. different plugins that are on separate breakers). My theater room has multiple 20 amp circuits running in so its easy to have different circuits for me. For the power to the amps I just used 3 12v rails from the power supply and tied them together to give power to the amps. Just keep an eye on the current draw of your amps and make sure the power supply has some overhead for even the max draw. For example one of my amps pulls 20A and the other pulls 25A (max), so I made sure my PS had at least 45A + overhead of around 10-20A
I'd be happy to help with the audio portion of the jukebox, I've built many more speakers than I have arcades 
I guess I was confused on the 2 line outs....
My 1st cab is running 600 watt amp, 2 10's and 2 boston acoustic tweets, and 2 mid-range, no issues on the same circuit.
I'm trying to find a sweet spot for sound w/o breaking the bank, I like those mini tweets from parts express.
You are going all out, power conditioner as well? good grief.
However you got my vote, go big or go home, cant ever have enough sound
