Nice set up. I can't imagine 2 - 15's. I have one L5 15" running on a Kicker ZX 1500.1 and it slams. I am also running the Wetsounds threesome and I am very happy with the result. I have a Kicker ZX 850.4 running them and they are stupid loud. The shop that did my set up used all Kicker with my boat and I went with their recommendations (they do over 200 boats a year) and are all boat owners. They also sell Arc and focal as well but they like the durablity of the kicker stuff in the boat, same reason you are using the Polk I am assuming. Overall looks like a killer set up. How many cabin speakers are you going to run? I have 6 Kicker RS 65.2 in the cabin and it is a good balance with the 15" and tower. I did put PAC controlers on each amp so I can control the sub level, cabin level, and tower level.
Here is the shop that did my work here in SoCal.
