What are the stock sizes of the front and rear speakers in my 2003 F-150 SuperCrew? I just bought it and I'm looking to upgrade the sound. I know I can mod any fit I want, but I'm looking for the easiest installation. Thanks in advance for the help, guys.

 

i believe most all recent year F150 speakers are 5X7s

 

Yup. 5x7's (same thing as 6x8's) all around. You could also fit a 6.5" round speaker in there, but you would have to do a little bit of cutting to make it fit.
