i've had a few different set-ups in my xs'.... first i had a sub box like the sub xclosures set-up. that worked great. i custom made my box so that i could open up the seats with the box in place and get to the cubby's below b/c i have tie-downs and stuff under there. the only bad side is that if u had a flat and had to get to ur jack, u'd have to remove ur center console to take the sub box out and then open up the seat to get underneath it.
now i have xtreme creations and love them. the only thing about this set-up that is inconvenient is the fact that i can't throw stuff in my back seat like i used to. i detail cars and most of the time i put the wet rags, brushes, bucket and stuff in the bed and everything else in the back seat. i can't do that without leaning the passenger seat onto the stuff back there in order for it to not fly into the speakers and subs in the middle of a turn.
just some food for thought...
