    What exactly should I be looking for when I go shopping for one? I have two JL 10"s and I want to put them into a 98 Accord sedan.

    You will most likely want to buy an enclosure that matches JL's reccomended enclosure sizes for sealed and ported boxes.

    Are you going for sound quality, or spl? How much space do you have for an enclosure?

    I'm going for sound quality. What's spl? Its a pretty big trunk, but I don't want the box to take up too much space. I want to still be able to fit my laundry and stuff in the trunk.

    more spl = louder. usually ported boxes create more spl versus sealed enclosures. really the size of the box depends on the volume of the enclosure recommended for your specific JL subs. like 04 said, check JL's site to find what size you need. also if the box is at the smaller end of the recommended volume, the more power you'll need to push them.

    I'd probably stick them in a 2.5 cuft net sealed enclosure for the two of them.

    I concur. I'd slap them in around a 2.5-2.8 cu ft enclosure... Have you bought these subs yet? You could go with something similarly priced, better sounding (in my opinion at least), that would require a smaller size... I'd go with the Image Dynamics ID v.3s

    Yeah, I already bought them. Does it matter if the box has two chambers or one? How can you tell if a box is sealed or not?

    No, one or two chambers is fine, it doesnt matter too much.

    A box is sealed if it doesnt have a port on it, or any openings.

    I'd go ahead and go with a 2 chamber design, 04 is right when he says it really doesn't matter, but this obviously isn't an SPL box, and a lil bit of bracing never hurt anyone :)

    Well he doesnt specify how large that enclosure is, and I can't tell by just looking at pictures of it. I would email him and ask how many cubic feet of airspace per chamber there is.

    He said that it is 2'8" long, 1'3" wide and 1'1" tall. So I guess that's about 3.3 cu ft. Is that too big?

    Shit, it's actually about 3.6 cu ft. Am I doing my math right?

    No, It would be closer to around 2.6 cubic feet assuming those dimensions you gave me were outer dimensions of the box (does the box have a center divder?). Which would work fine.

    assuming those are outer dimensions and the box is made of 3/4 in. material then....

    31.25" x 14.25" x 12.25" = 5455.078125 in.³

    12" x 12" x 12" = 1728 in.³

    5455.078125 in.³ / 1728 in.³ = 3.15687391..... ft.³

    correct?

    ok on the pdf file with that page, 0.75 is recommended. the dimensions they give are 18"W x 11"H x 10.25"D for each sub

    No, you have to subtract 1.5" from each dimension to get the internal airspace...

    I'd say that box on ebay would work great. In my opinon, you would have to have a box that is around 4 cubic feet or larger for it to be too big.
