From 92 through 2003 all the speakers are 5x8 inch in the doors and behind the seat in a single cab. Would bet that new models carry the same size.
6.5
5x7 6x8
Both the front door speakers and the speakers in the rear are standard Ford 6"x8".
6 X 8
if i am not mistaken the front door speakers are 6 in a half inch and the back speakers are 6x8 inch speakers.
from80's to 98 its a 6x8 in front and back
5x7
It depends on what size cab u have. I have an 89 regular cab and I only have one pair of speakers, they're 6.5" in the door speakers. I'm pretty sure that extended cabs have 6.5" up front and 5x7 in the rear
6x8 ALL DOORS
2 front door speakers 2 tweeters in front doors 2 rear door speakers
idiot- "The most common front door speaker size of a 1999 ford f150 is typically about 3 feet wide and 1 inch deep." actual answer 6x8's
8in in the rear & 6in in the front
