I grabbed a quick snapshot of the headunit only, since everything else simply retained the original saab look and covers (as they will look just like any other stock Saab).
Fitting a double din head unit in the dash isn't exactly a simple thing. Several parts (all plastic) have to be removed from inside the dash area to fit the head unit in there, since it isnt designed for a double din sized opening (its actually a little too short and a little too wide). The depth is also critical and will barely accomodate the unit. As you will notice the bezel is not flush with the SID, but instead mounts flush against the outise of it. That is all the depth there is and the unit will not go anyfurther back without making some serious modifications (which I am not going to do). Without further major modifications, a double din simple wont fit flush anyways without making a custom dash panel to house it (***uming one wants to keep the SID, which I do). I havent finished installing the extras for the head unit so it isnt permanent yet, nor quite centered, as I will have to remove it again later to finish it up, at which point I will make the custome brackets to mount it permanently. You also cannot use the double din mounting basket, as it will not fit, only the head unit itself will barely fit.
As for the SID, I had to remove the plastic part that it snapped into on its bottom edge, so without the head unit in place it would just fall down. Luckily the head unit bezel plastic clamps fill the hole perfectly and put a nice tight fit against the bottom of the SID holding it in place as it was before. Without the bezel, it would be loose and easily slide out (it also helps clamp the bezel in place.
Only other modifications, as mentioned was that I made custom speaker adapters to mount 5-1/4" speakers in the front doors (which originally housed 6-1/2") and adaptors for the rear deck to mount 6-1/2" speakers (which originally housed 6x9's). The dash speakers fit the Infinity 4" speakers perfectly (even the Infinity mounting holes lined up), so I was able to retain using all the originial mounting hardware without any cutting or modifications the the Saab itself.
The subwoofer is an Infinity Basslink located in the rear hatch. It's a self contained unit that sits just fine back there and requires no actual mounting. As such I didnt bother with any photos of that. Its a nice compact unit housing a 10" subwoofer and 10" passive radiator and puts out more bass than is needed. It is also self-powered with 100watts and does accept an addon card to provide 4 more channels at 25watts each, but I have no use for that.
I hadnt cleaned anything up yet so it's still a little dirty :P. It all works just fine. Only coplaint is that the location causes about 3/4 of an inch on the left side to not be visible to the driver due to the steering wheel, but that may or may not effect others (depends on where the position the steering wheel and how t hey have their seat adjusted).
