I am working on ordering some subwoofers for my new boat. I have limited areas and based on my rough measurements (I am going to go get more accurate ones as soon as the dealer has the boat inside) I should have about 2.7 cubic feet per sub before displacement (2 seperate boxes of different dimensions and I may have more like 3 cubes, but am working on the short side based on the measurements I have). I will be powering them with a Exile 2500.1 which puts out 2500 watts rms @ 1ohm (plan to run two dual 1 ohm subs so I can wire them to a 1 ohm load on the amp). I know the Q is 1000 watts RMS and the Xcon 1750. Will 1250 be enough for the Xcon? I have read such great things about it that I want to try it, but would stick with the Q's if they offer a performance advantage based on my power and space. Will one sub out perform the other? I am looking to get the most out of this set-up that I can in both clarity and spl. My last set up was 2 FI Q12's in 1 cube sealed boxes with 1250 rms each. I am also open to any other ideas!

Thank you for any help you can offer!

What is your budget and how much total room do you have to use?

And how good is your box building skill?

I don't think you could go wrong with either really. My vote would be for the Xcon though.

I think you will be very happy with an XCON sealed. Although small enclosures in an open air boat may not be too pleasing regardless.

What kind of boat and where are you putting them? Sometimes there are clever ways to make room for more bass on boats

I have about 2.7 cubes per sub (each in a seperate compartment). I am decent at making boxes, but not designing them (I have done sealed, but only ever built one ported). The dimensions are limited by the openings to each compartment. The toughest being the passenger which is 13.25x16.5 (but I have 30 inches to play with (at least) for the depth). Budget I do not want to go insane, but where these are priced are fine.

Why not do a ported 12" in that space instead? You're going to need good low-end reinforcement with an open-air environment like a boat, so ported and tuned in the low 30's might be a good thing to look at.

I could possibly do two ported 12's, but my problem is I do not know how to get the boxes to fit with slot ports and am not knowledgeable enough to design proper ported boxes. The space requirements for the two compartments make them very different size ise. I was told that perhaps a triangle port would be my best bet , or aeroports.

The passenger compartment has a issue with the opening. I can only get a 13.25x16.5 box in (and even at that may have to install the one side of the box once in the compartment)

post 6 in the following link shows the passenger compartment with the sub box build in it and post 12 shows how I would like to do the drivers side, except my ox will come out flush and will not have a fire extinguisher mounted next to it

The Boat is a Axis Wake A22. www.axiswake.com. The best places for subs are definitely under the helm (remove a kick panel and there is a good size area). The second best is the passenger storage compartment. I know I can fit 2 12's sealed easily. Once in these areas there is some space. The problem is there is little to no access to them. For example the drivers side has a lot of space above, but there is no way to get a higher box in the space.
