Help with dvd/stereo system please

[nmu98]

I am looking to upgrade my current factory system in my 2007 H2 to something that will play dvd's for the kids, and possibly play the dvd in monitors mounted in the rear headrests. I would also like to add a sub, nothing crazy, but I cannot have it take up any room or be in view.

Can any of you guys direct me tword some good products? maybe suggeestions?

I would also like to add sirius.
