Greetings!
As far as subs go, the Jensens were probably a good choice. You have a lower powered amplifier and need a more sensitive sub. I would suggest a MTX 4000 series or a set of Pioneers. These subs are more sensitive and will produce more spl with the lower power that your amplifier provides.
As far as placement, our cars do the best if you fire the subs straight up towards the hatch. Because of the angle of the glass, it makes the rear of the vehicle, in essence, a band-pass box, thus giving you more bass.
As far as hearing it outside the vehicle, the goal of sound is to keep the bass inside the vehicle, and produce higher spl (sound pressure levels). Keep in mind that you will lose exterior volume if you dynomat the car, but it will sound much better inside.
