I looked around on the postings, but never saw which of the OEM systems you had in your Truck? I am guessing it was NOT the premium (so to speak) B&O system - correct? If it was, shame on Ford for degrading the B&O name by matching it up with $h1t speakers!Credit to this kind stranger on Reddit, easiest speaker upgrade to the Mav using existing wiring harness and plug and play!

Ok, This is the product link here goes for $129, but its literally drop in and no existing modifications required includes upgrading the tweeters too.
Installed with this video guide (front)
Tweeter Installation video guide
* I recommend a plastic pry tool for door panels, you can easily get one from crutchfield or amazon.
* The plastics are tight, grip firmly and give it a little tug and eventually the plastic clips will give.
* The included foam on the new speaker is thick, the door panel will need some "Convincing" to snap back especially @ the bottom.
The video guide shows the door panel being tucked away to the side, I found that difficult.. imo Disconnecting the door lock mechanism was easy,
One tab and it releases as a whole and it just snaps back into place. You might need to move the actual manual door lock to "sync" its position.
Old vs new speaker
The tweeters will drop in to the housing using the original wiring harness and adaptor that comes in the box.
Overall I'm impressed at this drop in DIY, takes the guesswork of finding the correct depth, harness and fitment.
Huge improvement to the low end, mid's and high's. The audio system before the upgrade was very muddy even after messing with EQ settings.
