Assuming you can lay the thing down on its side it might fit. Folding the seats down, 45" deep is no problem. And 20" for the height works fine. 39" is still the question whether that can be squeezed in the width of the tailgate or not, it would be close.
I would definitely be laying down flat depth 20”so my concern really is the width at 45” and the height at 39”. Thank you.
Precious2k1 - Once you lay the media chest down (onto the backside of the media chest) and turn / rotate it so that one longways end will now enter into the Kia Soul
- the height becomes 20",
- the depth becomes 45", and
- the width becomes 39".
In this new orientation, it is the width of 39" which is the potential problem for getting the media chest through the hatch opening.
On the my 2014 (Generation 2) Kia Soul the hatch opening is ~39½in at the middle portion of the hatch while at the bottom of the hatch the width is more like 35in.
Thus if the hatch on the current Generation 3 Kia Soul is similarly sized & shaped, you will need to lift up the media chest for it to fit through the middle widest portion of the hatch opening. And also continue to support the media chest as it goes in so as not to damage the plastic trim at the bottom corners of the hatch opening.
The question is what are the hatch opening measurements on the current Kia Soul (Generation 3).
There is potentially such a small margin for error - will it fit or not - I think I'd cut a piece of cardboard the size of the cross section of the media chest and go to the rental car business (or a Kia dealer) to see if it'll fit before renting.
One other thing, if the media chest is in a packing box that'll likely have to be removed for the media chest to be able to fit.
