On trucks with the Sony audio system, the Ford website and brochures say "10 speakers." I count 8 (one each door, tweeters on from A pillars, center speaker, subwoofer).

The old trucks definitely had 10 speakers.

 

I wondered that too, I was aware of the 8 you mention above and that's it.

 

With some internet sleuthing I found the answer. Ford calls the rear speakers a "Rear Door Coaxial Speaker (woofer & tweeter)" and counts them as 2.

That's cheating, but there you go. lol

 

Thanks. A separate high mounted tweet as in the old truck would have been nice.

 

A pair of the best speakers I ever had were 6x9 Kenwood coaxial speakers I installed in my '78 F350 along with a Kenwood stereo. Sound was better than any truck I have ever owned up until the Lincoln MKC. I will be happy if the new truck matches the sound that old system produced.
