Stereo Modifications
The stock stereo system I received with my Probe when I bought it new from the lot was a Ford cassette AM/FM system with 4 speakers.  The stock system is very good, despite having only 4 speakers.  I had wanted a CD changer in the car, so decided to buy an aftermarket stereo.  I got a Denon system with 10 disc cd changer.  From there I had decided I wanted more power in the system, thus came into being what you see below.
Custom Stereo
      The stereo you are looking at is a Denon head unit w/10 disc changer 1240 watt system.  The components in the car consist of:

Denon Head unit (AM/FM, cassette, cd changer)
10 Disc Changer
2 600 Watt California Series A640 Profile Amps 4 outputs each
1 Denon 40 watt amp 2 output
14 output Acoustic Crossover
4 pioneer door/back seat speakers
2 mobile authority 12 inch subwoofers
2 infiniti kappas
2 jbl tweeters
1 noise suppressor
The stereo was the most difficult modification I did to this car.  I wanted something pretty elaborate.  I did the stereo piece by piece.  The most difficult part of this install is the removal of the door and side panels.  Once those are off the entire thing is a piece of cake. 
This stereo and a lot of other looks pretty complicated but is actually very simple.  The first thing to do is to route 2 4 gauge wires from the battery to the back of the car, in the hatch.  This will power all of the amps.  I used a pheonix gold power distributor and ran these power wires into it.  From there you can connect individual wires to connect to the amps, and of course the crossover.

Here is a schematic to this stereo:
