    Try looking at crutchfield, they have a custom box made just for the obs under the back seat, I would assume they have one for the nbs as well.

    www.supercrewsound.com is where i got mine. i opted for 2 seperate boxes, so i could keep a storage area between them. when im all done, i'll throw some pics up. should have my diamond plate and mdf center divider back wednesday. (im laid off still and got bored :-) )

    p.s. you wont find dimensions on any website that builds boxes. even after i ordered mine, they would give me dimensions to see if i could keep my under seat storage thingy and put the boxes inside it somehow. they just said they wont fit.

    i just posted my box plans above... check them out. They are for a raised seat box but can be adjusted for no seat lift.

    eh, I wouldn't waste money on a pre fab sub box. Some are ok but in reality they are tossed together fast and often leak. Not only that but for well less then half the cost you can make your own to your own specs.

    my boxes from supercrewsound.com even impressed the audio shop that did my install. they were well built, sealed nice, and they're sturdy as hell.
