KLF, you are right. There are 10 in mine.
From the front to the rear
1 centre speaker. I have seen this. It is an el cheapo. I would ignore its contribution.
2,3 at the front corners. Worth upgrading.
4,5 the tweeters in the A pillar. Can be replaced if you go with the component speakers. Or you can ignore if going for 2/3 ways in the doors.
6,7 in front doors. 6"x9" oval. Best candidate for replacement with 2/3 ways.
8,9 in rear doors. Another good candidate for replacement with 2/3 ways.
10 behind right third row seat. Opening is only half round. I believe this is the 8" subwoofer.
Correct me if I am wrong.
There's 2 more in the lift gate. So 12 total.
