Looking at a 2013 F150 Reg Cab 4x4 STX and have a couple of questions. I would like to get the same sound quality in a reg cab that the crews have with the factory NAV unit. My wife has a 2011 Platinum F150 and it sound Great. My experience with the reg cabs has been that they put cheap speakers, head units in the reg cab trucks. My last truck was a 2010 F350 XLT and the radio was terrible. Don't want to spend a fortune on the stereo.

Has anyone put a after market NAV/Stereo in a Reg Cab F150?

What size speakers are in the doors? How many speakers come in the F150 reg cabs? 2 in the doors and 2 behind the seats?

Any other information you have on a F150 STX would be appreciated!
