dude if your on team spead get with kenny man he will help u out if your on the team and so will matt, i say if your on a team use it for the help thats why they call it a team. both those guys has proven to be loud in whatever they do so go with that an to answer your question i would try under the window line 15's or 18's port back subs up that is the only setup i have seen in many suv's that are loud
didnt mean to rain on your post though man but u get what i am saying i hope and don 't take it the wrong way.
