Well Im no expert, and only know that the speaker kit will work with the installed amplifier. I also know the same has worked for others, and the amplifier will play them. I dont know if there's an upgraded amplifier available.
I could guess the 1800 dollar upcharge could be the Porsche style, get their margins in the options trick...... or they could really change the amplifier. I dont know.
A quick check could be to call the dealer for a replacement amp using a 12 speaker cars VIN, then look for an amp using an 18 speaker cars VIN
By the way, the only reason I even added the 18 speaker upgrade kit to my 12 speaker was because as soon as I realized there were blank plates in the doors where speakers should be, the plates annoyed me. Lol
