Thinking about replacing the speakers in my truck with something a little better and I'm not real good at eyeballing things. It has the 80" mid roof sleeper. I think the door speakers are 4"x6" and the ones on the ceiling in the sleeper look like 6.5".
What size are the speakers in a 2020 peterbilt 579
