I came up with right around 4.46 cubic feet of airspace using 3/4 wood/plexi. This is using the box calc on the site, it could be wrong ( I am feeling lazy today and going to trust the calc).

what if i just said forget about the portion of the box behind the seat and just did a box as the console only, so just a "rectangle" box guess you could say

Another great idea but it has not addressed the original suggestion "what came first the chicken or the egg". Solidify your decison on the subwoofer first, then build the box to the needed airspace of the sub. According to the diagram above I get ~ 2.56 cu. ft. of gross volume, you need to allow for internal space taken up by the sub or subs and of course the braces (you don't want that box to flex at all). If your heading on this path, choose the sub or subs to fit this airpace. A pair of Eclipse aluminum 10's or 12's would suffice quiet nicely, that is if you want to be spanked by bass with sq to boot. This box is a really easy box for you to build and with the right sub or subs in it will sound really good.

I agree completely that you need to start with the woofers and not the enclosure, but that being said you STILL have a design that is completely unworkable. If your woofers are firing into an airspace covered with plexi, you are building a bandpass box. I suggest this is the wrong design. especially since you still do not indicate any ports. If you build the enclosure you have pictured, you will end up with have an expensive vibrator with subs heating up the air inside the box until they blow.

I am guessing you want a plexi cover so you can show off your drivers, but so far all your designs will not produce anything *except* showing off your drivers. There will be no bass from this design. Also, is there a reason besides SPL that you are intent on using dual drivers?

How about this: you go back to the original design of the enclosure behind your seat, only leave off the part that sticks up between your seats. Make the rear enclosure sealed at about 2.2 cuft and mount a 12" Eclipse Titanium (or aluminum) facing the front in the area where you now show the part covered with the plexi. Put a nice speaker grill on it and forget about using plexi. Now THAT would rock your world.

i would love to get an eclipse driver, the only problem is, Eclipse is one of the very few brands that i can't get from my friend who owns an audio business, and that means that i will be paying up the a$$! any other suggestions that would be a good sub?

Your friend can't probably sell you a lexus as well, if he can then we'll talk. No offence to your friend, he probably has a respected shop with some good product lines, but sometimes the best deal... $ is not the best deal... that is the nice thing about competition. Good equipment costs good $, Eclipse is not overpriced at all, it is more expensive at dealer cost than most others, but the end result...awesome, I'm sure the posts about Eclipse subs show this. The nice thing that you have is a friend who's willing to give you a great deal. I ask my friends to support my business, however I do not have everything for all of them to meet their specific needs and fully expect someone else to get the deal. This does not mean that they won't continue to use my services and recommend it to other. Eclipse is a specialty line, ice cream with sprinkles if you will, not meat and potatoes like the Driftwood, Pionsneer, Slamasonic, Smellpine, Maid Marion, etc. They are all good brands but no one dealer can support them all. Maybe your friend should look into the Eclipse line, sounds like a job opportunity.

well how much would 1 12" titanium cost, or 1 12" alumium cost. i just turned 18, im just a kid, i have very limited funds, so thats why i am concerned with cost. What about JL, or Memphis.

JL and Memphis are both great sub brands, IMO. Can't got wrong with either of them.

Have you given any more thought to your proposed enclosure design issue?

I'd love to quote you on some new gear, however that is not the purpose of this site. I also would recommend that you support the local dealer in your area. Finally being in Canada sometimes has advantages, but as for Eclipse, warranty ends at the border. Find yourself a good knowledgeable Eclipse dealer and go for broke, you will be blown away by what a aluminum sub, yet a titanium sub would do, I prefer to add an Audio Control Epicenter to have bass that will shake you like a bowl of jello in an earthquake. Lightning Audio and JL also make some really good equipment, go find some pricing on all 3 models.

Also the reason I wanted to get 2 Drivers instead of one is that i already have an new amp. an A2200HCT which is 1600w RMS, that would be too much for just one sub, dont ya think. unless it is a sub that needs that much power. thats why all my ideas involved 2 drivers.
