So this was my 04 Dodge Durango.
Original system consisted of Kenwood XXV01 head unit, Kenwood KAC-x401m, Kenwood KAC-x501f, Morel Elate tweets and 5inch components in dash, Morel Elate 9inch midbass in doors, TC Sounds TC3000 15 in 2 cubes sealed.
Pics of original false-floor amp rack and sub enclosure. Molded in fiberglass out of the well left by removing the stow-away 3rd row seat. :
