I am planning on building a sub enclosure for a MM1040, should I go sealed or ported? Seems to me that building a sealed enclosure is easier but less efficient. I plan on putting the sub under my 02 sierra's rear seat, so I may have to get creative to fit it with only about 7" of space from the floor to the seat, foot and a half or so wide and maybe a foot long (sorry for not having exact dimensions at the moment). Its going to be powered with a pa880 unless any of you have any suggestions for an amp in the same price range that would work better.
Finally getting around to this build, already have the deck in and the rca's and amp remotes wired and ready to be hooked up.
