Noob question

So i'm finishing up my speaker installation and i'm debating if i should get a 4 channel amp and a sub

I want to just get one sub (since i don't listen to much hip-hop/rap and want to save space) and bridge two channels to power it while the other two go to the 6.5 components up front. Will my Clarion unit be able to power the rear 6x9s and send signals to the amp? if so how do i go about wiring it? do i just wire the stock harness to the HU?

I guess what i'm asking is-

is it all or nothing? like are all the speakers going to have to be all powered by the HU or just external amp or can it be both?

here's a diagram for a visual

You can power one set through the amp and the other through the head unit, I had mine set up like this for a while...BUT. THe 6x9s probably accept more wattage than the the 6.5s, so I'd actually plug the amp to the rear ones. THat's how I had it in my car...My amp gaves 75RMS per chan, front speakers used 45 rms, rear used 100, the HU gives 25.? RMS...so I just plugged front to radio and rear to amp.

use the amp for the speakers and get a seperate amp for the subs
