I will start by saying that I have not swapped speakers or added a sub to a car in over 20 years. The base system in the Bronco was quite terrible. The best I can explain it is that it sounded like someone was singing into a shoebox.
We did not go overboard and honestly bought what Best Buy had in stock as a test to plan for future upgrades. To my surprise swapping over to $30 kenwood 4 inch two way speaker in the dash made a significant change to the clarity of the sound at higher volumes. It takes all of 15 minutes to swap the dash speakers out.
I attempted to take pictures during the upgrade but they did not turn out as I would have liked. We did put together a high-level install video and sound comparison of factory vs upgrade while half of the Bronco's speakers had been replaced.
I also put together a wiring diagram however I do not have tools to test positive vs negative, maybe someone here will know based on the wire color? I determined based on ear however I am not 100% that I got it right.
**7/30/21 Edit:
Last night I replaced the 6.5 JBL speakers I put in (2.3 Ohm) with 6.5 Kicker CS 4 Ohm speakers for the kick panels. I also rewired the JBL Bass ProGo with 14 gauge speaker wire.
The JBL now sounds amazing. I actually had to turn down the bass knob to 50% and drop the Bass on the received down to 35%.
Edit to add update video:
The JBL Bass Pro Go turned out to be exceptional after changing out the wiring. We also swapped for 4 ohm 6.5 kickpanel speakers.
The end result sounds better than the B&O in our 2021 F250.
