in that truck if the enclosure is behind the seats you will have to face the subs forward, unless you are really short. i have an s10 ext cab and im 6'1" and i only have about 14-15" of depth behind my seat at a height of around 20" so you'll have to do alot of measuring to figure just how much room you really have with your seats in a comfortable position. higher pre out voltage is better but from what i understand it isn't really that big of a difference from 2-4 volts(please correct me if im wrong). if you can, definitely do a build log and post up pictures i would love to see how it turns out.
