Hi guys, I finally have purchased all of the components for the first stage of my system except for the subwoofer. As the title says I am trying to decide on the size and box type to use. I have a 2001 Jetta and will be using Cadence amps which are very long. Earlier I was trying to fit a 15" Q in a slot port enclosure and was having a very hard time fitting everything in my trunk and still having access to my spare tire. I have only heard sealed enclosures before, would I benefit from the larger enclosure and reduced trunk space? How would a slot ported 12" Q compare to sealed 15"? These options seem much better for my limited trunk space. What do you guys think I should do? Thanks!
