I just bought 2 10" dcons, and now i need to build an enclosure. Im just not sure what what style I should do. They're going into my 1990 bmw 325i. The trunk is pretty much a steel coffin, there is no opening in the rear seat or anything. What i was thinking of doing is removing the rear speakers and porting directly through those holes (1 port per sub). Anyways, what box style best suits these subs? Should I go with subs facing rear, porting through the top? Some have suggested I build a bandpass setup, but I have no idea how to make one of those. If anyone feels kind enough to make up some blueprints, the trunk space I have to work with is 15.5" high by 3ft wide, and as deep as needed to need the recommended ported enclosure specs (1.25 cu.ft. @ 28-33hz). Thanks alot. Oh, and Im going for sound quality over loudness. edit: Oh ya, and im gunna be running these at 250w each, if that matters.
