Can I only use this with a front and rear system with sub or also with a two-way front system and a sub?

My plan is to put a coaxial 4" in the stock dash position with a separate amp and in each door two 6" midbass speakers also powered by a separate amp and ofcourse a trunk mounted subwoofer.

I would like to know if the Alpine PXA-H600 will allow me to time-align the coaxials, midbasses and subwoofer with each other.

Also can the PXA-H600 be fully controlled from a Ai-Net capable Alpine headunit or do you have to use the included remote as well?
