i think your wiring diagram has some flaws. 4/0 is labeled but i think it should be 4awg. correct?
the amps aren't shown as grounded, i assume they are.
the speaker wiring outputs aren't +12V.
wiring should be color coded.
HU RCA's
front out to tweeter amp
rear out to mid/woofer amp
sub out to sub amps
move at least two of those tweeters behind you, between the mids. like a dual MTM arrangement. otherwise the rear will sound weird. moving four back there would be even better. up front, tweeter in pillar and tweeter in kick.
i think you'll be lacking midbass. this is where a pair of nice 8" midbass would come in handy, some pro audio woofers on a dedicated amp. these would be best implemented in your rear mid enclosure. it looks like you expect the 5-1/4 to handle midbass duty, but they won't keep up.
