Wiring boat tower speakers

My tower speakers just got a little more complicated.

I have a pair of Kicker KMT6 speakers on my tower and 2 pair of Polk DB651 speakers. The Kickers are in a single enclosure, wired at 4ohms with a RMS of 150 watts. The Polks are able to be wired independently, in series or in parallel as binding posts are exposed and I can set them up however I want. They are 60w RMS

My biggest issue is the number of wires running up to the tower. Right now, I have just 2 channels run up on the tower and I would prefer not to run more speaker wire up as I will have to enlarge the holes from the boat to the tower. I really don't want to do that.

Assumption 1: I assume that you should not wire speakers of different power capacities together as one could be under driven and one could be over driven. Is that correct?

If that is correct, then I could see wiring the two KMT6 pods together in parallel to run them at 2 ohms.

That would leave 4 speakers to be wired. Could I run each double pod in series at 8 ohms and then bring them together in parallel to make it 4 omhs?

How does doing that impact the wattage required to run the speakers. I know that in parallel, each speaker gets the same wattage. In series, does the same still hold true or does that change because the voltage across each now changes.

Last question for now has to do with speaker wire size if I put the Polks on 1 channel and the Kicker's on another channel, What size would I need in that case or would the same rules apply as if it was one speaker?

Thanks for helping me to become educated on how best to wire these speakers.
