Nice gear, would skip the changer .. a bit obsolete considering the digital source from the iPod.
I went with the
Kenwood DNX8120
Diamond Audio Hex S600 Comps front and rear.
Diamond Audio D6700.4 Mids and Highs
Diamond Audio Hex Pro 12 subs
Diamond Audio D61200.1 Sub amp
The sub enclose is a tiny 1.8 cubic foot box, ideal for those subs, with its greatest depth around 5" - those are shallow mount subs which saves cargo space. The Kenwood unit is the current standard in topshelf Double Din DVD / Touch Screen, Navigation, bluetooth, iPod and fits like a glove .. of course it does not take voice commands but it does have the sound.
Give this stuff a look before you make your final choices ..
