I think this is a part of the issue, they are mounted on the sides of the boat with probably 3-4" behind them. I will look at squeezing in an enclosure behind it.
Also, great suggestion to replace 1 wire first and test it.
Thanks for the help.

This might help you design the enclosure:
Woofer Size --- Enclosure Volume
4" ======== .25 - .39 cubic feet
6" ======== .35 - .54 cubic feet
8" ======== .54 - .96 cubic feet
10" ======= .96 - 1.8 cubic feet
12" ======= 1.8 - 3.5 cubic feet
15" ======= 3.5 - 8 cubic feet
Aim for the high side of the volume recommendation if at all possible and make the boxes out of something dense. Anything you can do to avoid parallel surfaces inside the enclosure will help too. Parallel surfaces support standing waves and will make the frequency response less flat. Most boxy home speakers avoid this by adding insulation to the inside of the enclosure to stop standing wave forms. Adding it to an irregular box would not be a bad thing. Don't have to go crazy with it.
There are commercially available marine speaker enclosures. Might find something perfect...
