2 Amplifiers

Can someone help me?  need to know what i need and how to install two amplifiers. I have a Hifonics BX1605D thats one ohm stability and thats how i want to hook it up. Its peak power is 3200 watts and at 1ohm its 1600 watts x 1. This amp is going to be powering 2 Audiobahn AW1200N's, their peak RMS power is 700 watts and they are dual 4ohms voice coils. My other amp is a Hifonics TX4405 its peak power is 880 watts its a 4 channel amp. I want to wire it at 4ohms and the peak power for that is 55 watts x 4 channels, Its gonna be powering 2 front door Sony XS-V1635X's their peak power is 250 watts and  its recommended power range is 2-65 watts RMS and the rear speakers are Infiniti Reference 6402cf  120 watt peak and the recommended power range is  2-40 watts RMS.  My in dash receiver is a Panasonic CQ-C7301U it has 3 pre amp outputs, front, rear, and subwoofer.

Ok now that i gave u all my info,  ill explain a little more on what exactly i need to know. For my first amp the one thats goin to be powering my subs i wanted to get a 0 gauge wiring kit is that right or wrong? Heres where my problem comes in , see i want to hook both amps up to a distribution block and i dont know what kind to get and for the second amp i wanted to use a 4 gauge wiring kit, but do i really need to buy a whole other kit? How do u wire a 0 gauge and a 4 gauge together. So basically i want to know all the steps on how to wire those two amps to a distribution block and everywhere else they need to be connected and also everything i need to complete the entire installation of the amps. Thank you in advance.
