Kia Sorento Special Edition 2006

I have just come home with a brand new Kia Sorento Special Edition Turbo Diesel, from the Kia Dealer in Cebu City, Philippines.

So far so good. The car is quick, responsieve, and all that. But the issue is car stereo. The car is dealer equipped with a Jensen MP8610BT headunit, and -I guess- factory installed speakers, 6,5 inches. The Jensen have allready collapsed, and I'll get a new unit, over the weekend....
As it happens, I come from Northern Europe, but I now live in the Philippines, due to ill health. (Psoriasis arthritis) Now, it's a little bit of a problem, the missus don't fancy me filling up the car with speakers and cables, all over the place. That means, I am somewhat limited by "force of nature" as to what I can install in this car.
Which is why I'd like to ask the esteemed forum about tips and suggestions, when it comes to get as much music as possible, of of the space available.
In Europe, I used Kenwood and Alpine stuff, but it is a bit different, because of the RDS (Radio Data System) The speakers was Boston Acoustics in the doors, and i n the trunk, I had a self constructed box with a volum of 100 liter, with four Seas speakers. The amp was 4x100 watts...
I can't do that now, I'm afraid. The wife says I'm too old for that, and so on...
Any suggestions and ideas will be well recieved!

I just did a deck in one of those today.  Unfortunately Metra doesn't make a dash kit or harness for that thing yet, so you may have to do some customization to get a new deck in there.  For me that included iso-mounting the deck by drilling new holes in the factory brackets to hold the deck in the right place, and glueing a piece of ABS plastic below the radio to fill the rest of the gap.  Just thought I would give you a heads up.  Good luck!

Hi, Steven, -as it happens, the Jensen are built by DIN size. You van find the spec's here:

In all honesty, I might add, I've been "fooling around" with this unit today, and after a little back and forth, I decided to try to -simply- reset it! And that did the trick, would you believe it! Now it plays cd's and radio to my great relief...
But I am still considering a change, -at least, of the speakers!
As far as the mounting is concerend, this one is dealer mounted, and I don't know "what's in the back", so to speak. However, I have the impression this is fairly simular to other brands, -more or less, at least!
A friend of mine had a Pansonic, with JBL's in a Volvo 740, -to my ears, that was a well sounding combination?
Another friend swears to Alpine head units and speakers.
That sounds well too, -and as far as I am concerned, the importance lies in the way the stereo can play, and reproduce music, -not nessesarily how loud it can play!
