First off, many thanks for the inspiration of previous 'How To's' especially Pottsy for head unit removal and speaker replacement as well as those contributors for iPod icelink.
Firstly, I replaced the existing speakers, front and rear with Kenwood 17cms (Components in the front). An improvement but basically the headunit is just not up to it. Amplification was required.
Power cable run from the battery, fed in to the the battery termination 'box' with a carefully drilled hole.
Although not close to the battery, I ran the cable through a main loom grommet found in upper drivers footwell.
Because of a lack of pre-out in the headunit, speaker cables were run front to back, through amp 'high inputs' and then back to pick up again at the headunit (I used an Autoleads SOT lead to save cutting the original wiring).
The amps (a Sony 4 channel for the front and rear speakers and an amplied Pioneer active sub box) are mounted neatly under the seats. Although the routing of this volume of wiring takes time in order for the seats to return to their 'down position'. However, this way none of the boot space is taken up and the sub is more effective as it is within the cabin space.
Th Pioneer box has a bass controller, which is a nice feaure but another wire to run. This is housed within the roll top draw that is home to cupholders.
With the sound system sorted my attention turned to entertaining the children.
As I wanted to put a DVD player and hook up for a Playstation 2 in the glove box, it was easier to take the glovebox right out - 2 screws, 2 plastic studs in the front lip, 2 'bolts' under the end panel of the dash, another that is exposed with the cetre console removed and a 'hidden' screw/bolt that secures the rear of the glove box to a 'hanger'

My kids have a 'Buzz' game which have specific conrollers for PS, requiring a USB connection, which was a bit of a pain as wireless controllers that suit most games are literally plug and play. Whilst I was fitting the USB I also fitted a remote reset button for PS. The remote infrared eye for the DVD is run down the centre console to the rear.

I had the 6.5" screens professionally fitted by Veba with some 'flush mounts'. These screens have an infrared transmitter for wireless headphones and also link with an 'AV switcher' (mounted above passenger kick panel) that allows either video source to be shown on either screen (no arguing from the back hopefully).
The screen cables were awkward to run down the inside of the seat backs as the clips that hold them on are delicate ( 3 large and stiff fixings at the top, smaller clips down the 'non airbag' side) If fact, although I was careful, my dealer managed to break them when I had a seat cover changed recently!
Earthing points for most of the visual kit was picked up on a stud located on the passenger side inner wing.
Finally Dension icelink was installed with lead through to silver cubby under radio.
No doubt I have been short on detail at times and would welcome any questions.
A happy SJ.
