Yes, coaxials are the way to go, however, the 10" Wet Sounds Rev-10 HLCD is the exception. With its extra surface area, it really balances out with powerful compression driver.
The difference between 2 pair of 6.5 and a single pair of 8": The 4 6.5" has more surface area, both in the mid-bass come and tweeter, so it will deliver greater peak output compare to two 8". However, the larger 8" will deliver deeper mid-bass, netting a smoother more natural sound. But with proper power, the 8" will deliver plenty of output. The typical 8 will also handle more wattage than the typical 6.5", so we can also drive the single pair of 8" with more wattage then a single pair of 6.5", which equals more output.
For sub box, I would really suggest a custom built box that A) fits the boat and B) is designed to optimize the woofer and C) an enclosure thats designed for the marine environment. You wont get these from an off the shelf box. Executed right, you may not lose any leg room under the helm.

That explains alot and makes more sense now. Now the hard part in deciding to go 2 or 4 speakers on the tower. Four always looks better but I like the deeper mid-bass and don't think a pair of 8s with a pair of 6.5s would be a cost effective option.

I totally get the look of 2 pods v's 4 pods. There can be some challenges with mixing different size speakers, mainly the amp selection. From a cost position, there may not be much of a cost difference between four 8" and two 6.5" and two 8". At that point, step up to four 8". The amp choice to drive the 2 pair of same size/type speakers is much easier also.

'17 Craz Audio Questions.
I am installing a set of matching bow speakers, that I got off Brett, and will be powering those off the deck. I also purchased a kicker 800.5 to run the in boats in the cockpit and a 12" kicker sub in a box under the helm. For the towers I got a pair of the kicker KMT 6.5 inch tower speaker sets that I will be running off another kicker 400.4 amp that I will bridge. I plan to see how all this works first, and if there isn't enough sound from the 6.5 towers I will add another pair of KM8's and another amp for those.

You should run the additional bow speakers off the 800.5 also, instead of the head unit.

Good idea. I'll just have to adjust the gain to the front speakers so that they aren't out of balance the cockpit speakers

Yes, you should drive the bow speakers with the amp. It will do this without hesitation. Depending on the head unit, you can still have the ability to fade as well.
Just note that the 400.4 may not like those KMT67 bridged. It has a lower than 4 ohm impedance and tends to put an amp into protect mode when bridged on a 4 chnl amp. The KXM400.2 is a more stable options and the Wet Sounds HTX-2 would push then a little better.

Just measured the KMT67 and they are 3.8Ω each at the speaker. I then attached 2m of 16ga wire to one and remeasured and it's right at 4.1Ω. It should be ok. We'll see!
In retrospect the 400.2 would have been better as it's 2Ω stable for 200W x 2.
