Hey fam I want to make sure I have everything and see if it is possible to buy these without running into issues with the speakers and the amp. This is what I have in mind so far

This is going into the Z box
Kicker CompRT 10" 1-Ohm Subwoofer

These will replace the two front speakers along with the ones on each mirrors
Kicker CSS65

and obviously the amp to amp the speakers+sub
Kicker 46CXA4001 Car Audio Class D Amp Mono 800W Peak Sub Amplifier

I’m no expert, but I don’t think that amp is made to power your components. Only the sub.
