I own the following items: http://www.kaptionaudio.com/manuals/SPLManual.pdf ( I have the 15 inch) http://www.kaptionaudio.com/manuals/KaptionD-Class.pdf (biggest amp they make) I am trying to build a loud, clean system. The dimensions and information are in the pdf for the sub. Now, I listen mostly to rap, some rock but mostly rap and otherwise a mixed back. I believe sealed is the way to go because I like the clean, clear bass... I will be leaving in the third row of seating in, but have it flipped up (or maybe I should take it out). I need to use the space above the sub for the transfer of some goods etc... Should I center the sub, put it towards the rear seats or the rear window? Has anyone here done an install of 1 - 15 in a Tahoe?
