I would love to go back to OE speakers but from what I read on this forum, they are all worn out by now.
Even if they are available new from Porsche, I can only imagine the cost.

I don't know about worn out... More like out dated and very likely to be hacked up like yours. I chose to get rid of mine because of my preference for a higher performance system. The previous owner did hack in a new head unit, but other than a bit of rewiring, everything was still in place and worked okay for what it was.
If you aren't just dying to have a hi-po audio system, go back with used factory stuff. Properly matched up and wired it can sound just fine at moderate listening levels. Figure out what all you need, as me or someone else here may just have an extra or two lying about.

You should search to verify that my information is correct unless someone else chimes in. I believe that all the speakers except for the 6" were 4ohms. The 6" was 2ohms.
There are 3 notches at the base of the plastic holding the grill. You pry up at these points were the "prongs" hold the grill to the mounting ring. You stand an excellent chance of cracking the plastic.
That is what the originals were in the rear deck of my 1991. The speaker foam was nearly gone.

I'm removing all my old speakers because they are (in a 79) single voice and of really poor quality 31 years later.
Speakers technology evolved quite a lot, and those just doesn't cut it anymore. Even if they would be brand new.
I went with 4" 3 ways in the doors and 6"x9" 5 ways on the rear quarter panel. (Like if I had a 8 speakers systems!)
I plan to do a rear seat delete and put 2 flat sub there.
The sound quality is just like night and day.
Of course the purist around here don't like it cuz it change the look a bit of the door and panel. Bleh!

This is my attempt to update the system and retain the panels for any future owner who wants to go back in time.

These 928's are timeless but they would have continued to evolved if they were still being produced. Why not enjoy technological change ?

There is no such thing as a pure original equipment car unless it was rolled from the assembly line to the museum floor. If that car was 20 years or more old it would not function without being updated in some fashion whether it is tires, fuel lines or anything else.

Well, Sometimes you have to know when to quit!
My quest for OE audio purity has ended. I will not be pure.
I determined that the PO had used the wires to the B pillar woofer to power the MB Quart rear speakers, serving the tweeter through the crossover and the rearmost midrange in series with the larger B pillar speakers.
It was, and continues to be, a 4 channel system. Once I connected the Quarts to the two rear channels of the amp I had sound. Frankly, it sounds fine to my less than discriminating ears. Good fidelity, base a bit weak, but probably no more so than with stock speakers. And only I know that just four of the six amp channels are being used and that MB Quart speakers are hiding behind the stock grills. A guy has to know when to admit defeat. I have tunes and it looks stock.Thanks to all for your help.

Good moves all around!

There are a few 6.5" subwoofers available that would require a depth extender ring to avoid hacking anything if you want more bass.

Mostly true, especially for car stereo, but, on the other hand, my home main speakers are 1982 Magepan Tympani IV's. They can still compete strongly against current high-end speakers costing quite a bit more than they did when new. The highest quality speakers when the car was new would still be pretty good now, but the stock speakers were not the highest quality even back then.

I think car speakers improved a lot more.. miniaturization and such.
