    What kind of 18 is it? You don't have 7 cubic feet there, no matter what box you build. Depending on the EBP of the sub though, you may be able to go with a smaller sealed enclosure and still get low bass.

    are you really an idiot? or did you read a speaker book memorize some words and acronyms and think you can give advice now?

    10.5 gross. Figure a cube and a half for 1.5 sheets of 3/4 and bracing. Then knock out another cube and a half to 2 cube for port displacement and it's about 7-7.5 cube.

    If you have all that space, use it. Keep in mind if you have the port too close to a wall inside your cabin it won't function properly. I could do up a cutsheet for you if you have EXACT outside dimensions.
