Putting the port in the back of the box is a bit tricky. You have to design the port to be out of phase with the driver. The hard part is the only way to do that is with the enclosure in the boat and a scope. You can design theoretical but it changes once you put it in the boat. The enclose area of the engine bay will change things. That is why you almost always see the port on the same face as the driver.

your talking about an enclosed area compared to open. I would guess with the openess and engine noise you would need 3-4 times what you had in your truck to come somewhat close. Its just a boat man, as long as I can hear it thats all that matters

Thanks for the information. I am searching all possible avenues of approach in this situation. Thinking something sealed on the side of the cockpit, or still with the ported under the bench, lots of debating to do. Nordics arent known for their storage space, so I would like to maintain as much as I can in that regard, so the sealed may be more of an attractive option.

im wondering the same, i have the four stock speakers run off the deck, i wan tot keep them that way. I just bought two 12 inch subs with a 1200 watt rockford fosgate amp to run them, im going to put them up in the cuddy, i bought another 500 watt rockford fosgate amp to run another four speakers that i will hide under the side skirts, i will run the remote wire off a toggle switch so i can turn the amps off when im at the beach and dont want to drain the batteries.

JL makes a FG box for their marine sub. Looks nice.
