depends on what sub(s) als o its better to build your own enclosure rather than buy a prefab box unless you buy one made by the manufacturor of the sub...you can probably fit anything in a jeep...big trunk
The problem is i have one 10in made by Infinity and they dont make enclosures from what i know of but is there any company that prefabs sealed boxes of good quality
no not really...the problem is that each subwoofer has different specs so for you to get optimum sound you would have to build(or pay an audio shop) a box to the manufactures specs...although since thats not a high level sub just find out what cubic volume it needs and go to a store like bestbuy or curcuit city and find an enclosure with the same volume...wont sound as good as it could but itll be ok
