so ill be having 1 Crunch P1000.1 amp powering 2
Kicker 07CVR10-4
and ill have 2 PDX-1.1000 powering 2
SWX-1243D

how would i do this?  

It's really not that hard.  You'll need a heavy power wire to feed both amps, 4 guage just probably wouldn't be quite enough.  While 1/0 guage is expensive it will give you more room to expand in the future.  After that all you need is good installation techniques, a distribution block, extra RCA wires and go to town.  Just remember that more isn't necessarily better, and are you sure your charging system in your car is up to the task?  Do you have at least the "BIG 3" done?  This and many many more things are to be considered when trying an installation like this.  Make absolutely sure that all the speakers are wired correctly because phase issues with multiple subs can be very difficult to detect or even find.  There's alot to do for an install like this but if you keep to the basics the rest should fall into place for you, plus if you get stuck myself and others are always on here to help or perhaps a local shop could lend a hand as well.  Good Luck and I hope it turns out like you're wanting it to.
