The deck is easy to install. If you have a harness it might only take like 30 minutes. Like you saw in the car you only have to take out the cupholder, pop the trim plate and six screws later the deck is laying on your shift knob.
If you have to splice your own harness maybe longer. There is a Subaru part from the forester if you want to fill the DIN oem like, but you can also buy a Universal DIN from lie crutchfield or someting. I have not fiddled with the speakers so I don't know how big you can fit in the front or anything but I've heard so 6.5s will work with a little spacer thing made of mdf.
I got my stereo from
