I just bought an AA Assassin 10" for my single cab 95 f150. On the website it says this sub is good in small ported boxes, but Im not all that confident that I could build a good ported box, especially in the area I have to fit this thing. Here is the design I came up with, it's not to scale, but with 3/4" mdf the inner volume is about 1.3 cubic ft. I cant find any info or specs for volume for the Assassin, does anybody know? Is 1.3 ft too large?
