New system change...

Yea im sick.

Ive decided im going to bridge my 2 amps together, and run 2000w to a single 10" SSA XCON 10" driver.

Luckily i can use the same bow box as it will result in a 30-31hz tuning still. I should gain back some storage and be just as loud if not a bit louder in the bass region ...

The sub alone weighs 57lbs!

Pretty excited to see how it sounds!

What is the gauge of the power cable AND ground?

P=IE (Power = Voltage x current), so I=P/E and if the gauge isn't adequate, your amp will never put out the power you want, it will overheat and it will distort badly at high power levels.

0/1 from alt to battery / distro blocks, and about 1 - 2ft max of 4guage stretch.

The amps are made to be strap-able, each has their own 4awg power. 10gauge going to speaker.

150amp battery isolator, micor processor controlled. Monitors voltage of both batteries and switches between. 150amp breaker and 135amp breaker, dual batteries. Blue top for starting, pumps, and dash lights. Exide deep cycle for amps. Looking at a 220amp HO alt, but haven't made the plunge yet.

Just some general comments.
I can see the influence of the car stereo forums here. And if you are looking to go the maximum SPL route then I understand. Paper is light and responsive.
SPL woofers are typically a little higher resonance, a little higher 'Q' with lighter moving mass and greater motor strength. They are designed to tune a little higher than normal and combine with the vehicle cabin effect for maximum output at a particular frequency. They are not designed to be linear.
There are a few cautionary notes as well. Paper tends to absorb moisture in a boat, especially when under cover. Over time this breaks down the structural integrity of the cone. Also, as a paper cone absorbs moisture it will change its parameters. And believe me an MDF enclosure does breath a little.
I find it interesting that four woofers ranging from 10 to 18-inches use the same voice coil with the same motor structure. Thats not terribly sophisticated. I wouldn't consider that as on option if I wanted a balance with SQ or a more musical bass.
All woofers are by design a trade-off. You cannot obtain something extra in excessive performance without seriously sacrificing another attribute. I just want everyone to understand that there is no magic pill. Most woofers strike a balance with their design objectives.
These comments aren't intended to be critical as much as informative for others.
But if you are looking for the max bump and are aware of a few of these things then I certainly get it and have no problem with the choice.
So keep on keepin' on.

it should be pretty clear i am going for max bump. I find that sound quality gets very difficult to achieve in a boat due to the surrounding elements.

Im aware of the issues running paper cones in a boat, but if im not mistaken aren't they coated with something? Seems that way on my current subwoofers. Luckily I get these speakers at under $300 each, so if they are to get damaged it's not a terrible loss.

It is a bit stange that the 18 uses the same coils and motor as the 10, but hey, maybe that will give the 10 a bit more SQL.

You are absolutely right about the car audio forums influence.. what can i say, i like it loud =D
