Wiring 6 speakers with a 4 channel amp (Gurus)

I have did the searching and found nothing specific to my needs.

What I have

PPI PCX-4125 4 X 125 @ 4 ohms (I amsure you stereo gurus will know this amp.)

6 Infinity Kappa 6.5 coaxials

Looking to wire them the best way possible while still maintaining the 4 ohm load to the speakers, unless it would be better to run a different ohm load to the speakers. I understand the general concepts of stereo wiring but ohm loads confuse me when it comes to the wiring part. I do understand that the higher the ohm load to the speakers the better sound quality you get. They are all going on the tower so Clarity is probably of my upmost concern. I will also try this in the boats and accessories forum.

Thanks for the help in advance.
