I just wanted to add a few notes to my speaker upgrade. I was in a time cruch so no tutorial or pics, but for anyone wanting to do a simple speaker swap, here is the route I went.
Vehicle is a 2018 Ram Power Wagon with the 8.4" Uconnect (no Nav) and 6 factory speakers.
I went with the Kenwood Excelon KFC-XP6903C up front (the kit includes 3.5" mid-range speakers for the dash location) and 6x9's for the doors. For the rear, I used the Kenwood Excelon KFC-X694. I used Metra 72-6514 adapters for the front and rear door speakers and 72-7902 adapters for the dash speakers. I also put Dynamat Xtreme (10455) inside the door skins. The 36 sq ft bulk kit is plenty for all 4 doors.
As far as fitment, the front door speakers are pretty much drop in. They just clear the window frame mechanism. I cut strips of Dynamat and used them as a gasket between the speaker and the door panel. It gave just a tad more clearance and provided a good seal. The rear speakers required a 1/4" spacer to clear the rear window mechanism. The X694 set did not come with spacers but the XP6903C did, so I just used those. For the rear, I used a thin bead of epoxy between the speaker and the spacer then I used 1/4" foam weather seal between the spacer and the door skin.
I did the 4 ohm resistor mod for the dash speakers. I soldered the resistor in-line. I ordered the Dayton Audio 4 ohm/10W reistors from Parts Express. I used the foram weather strip for the back of the dask speakers. The hole is too open for a true seal, but it did it to eliminate any chance of rattling. I also wrapped the Metra adapter with the resistor with Tesa wire loom tape - nice stuff.
The speakers themselves sound great over the factory. Deeper base, better mids and highs without being too bright...I'm really impressed with the soundstage and the separation of instruments. I ma very happy with the upgrade.
I would rate the install a 4/5 out of 10 for the difficulty due to the resistor soldering and pulling the inner door panels off to do the Dynamat. If you just wanted to drop in the speakers and crimp the resistors in for the front speakers, it would be an easy 3/10.
