I don’t know the answer to your question, but I bet you can find in one of these links. And then some…that is what I did when I made a box for a different car. Hope this helps

Sealed - is the most common subwoofer box and easiest to build. These boxes will give the flattest frequency response, and best overall sound quality (especially at lower frequencies). The subwoofer enclosure internal volume should be as close as possible to the recommended by the manufacturer. If a subwoofer box is smaller than what it is supposed to be, the sound will be tighter, but more amplifier power will be required. If the subwoofer box is too big, then the sound will be muddy.
Ported - boxes are usually bigger in size than sealed and have a "tube" (port) that lets some air out of the box. The idea of a ported box is that the speaker port pushes (or pulls) air at the same time as the woofer, reinforcing bass. The subwoofer box itself acts as an amplifier, yielding to more bass than a sealed enclosure (3 to 4 dB). Ported subwoofer boxes do not have a linear frequency response. If the subwoofer enclosures are not built according to specifications, they will not sound good. The subwoofer box design acts as a filter, cutting off lower frequencies.
Band Pass - enclosures consist of a woofer between a sealed and ported box. Bandpass subwoofer boxes will yield more bass than sealed and ported subwoofer boxes (especially at lower frequencies), but over a narrower frequency range. Since the subwoofer enclosure acts as a filter, mechanically blocking lower and upper frequencies, a crossover is not needed in most cases. These subwoofer enclosures are usually big, and very unforgiving when precise volumes and port sizes are not followed. Bandpass subwoofer boxes also tend to mask distortion. If you can't hear distortion and turn your stereo down in time, you could damage your subs.

One thing to remember is that sealed boxes require much more power to produce the same amout of bass. So if power is a concern, that might be something to consider.

Agree with every one above
people usually just go with ported boxes when they don’t have powerful subs, but if you do have powerful subs then you would want a sealed box.

Just in case anyone needs it, JL Audio has a pretty good tutorial on the different enclosure designs here . If you check out that page be sure to look at each of the blue text links at the top of it. They go over the designs mentioned here as well as some others. The layout and attributes of each enclosure design is explained there. It's the most understandable and credible source of information on the subject that I've found so far.
I too would reccomend going with a sealed box. Each type of enclosure has its advantages. Depending on what your looking for in a sub, any one of those might be the best choice for you. I reccomend the sealed box because of its simplicity, size, and cost.
Another great source of information on the topic is Rotarygod's post here . Alot of that thread seems to be a bit of a flame war so it may not be worth your time to read the whole thing.
If anyone feels like taking the time to learn about sub boxes, these links and the ones posted by momo are great places to start. In the meantime, keep in mind that each enclosure might be the best depending on the situation. To determine which one is best, figure out your requirements.
Hope this helps.
My first post btw...
