Full audio system fronts, rears and subs

I've been searching the internet and YouTube, and crutchfield etc for hours and can't quite come across the right answers


I have a couple of questions on how to wire up two amps.

I have
-pioneer Avh x4800 HU
-Polk DB 6501 Component speakers
-Polk DB 351 coaxial
-two 12" lightning audio subwoofers
-lightning audio L-1250 500 Watt mono amp
-lightning audio L-4300 4-channel amp

I know

fronts - tweeter/mid --> crossover--> amp (FL/FR)

Rears - coaxial --> amp (L/R)

** this is where I'm unsure of where the speakers are going to get signal from

Do I get an RCA split and connect them through input and output (mono amp for sub is already connected with RCAs)
