100% get OEM. I had major issues with the front camera system after a non-OEM windshield replacement (at the dealer no less). You can see my post here about it: https://www.f150gen14.com/forum/threads/front-camera-fault-level-kit.23347/post-455233
I did basically what you're after in my truck due to blown rear door speakers, also B&O 8ch non-unleashed. I used Kicker KS instead because I preferred the silk-domed tweeters and they were still pretty sensitive. Also opted for KS because they have 6x9 components which were much less common in...
What sound system does your truck have? The 8ch is listed earlier in this thread and I have the rest of the wiring diagrams laying around somewhere.

@Johnlar beat me to it. That's one of the tings I tried (unsuccessfully) but that might allow a successful calibration if your window will allow it. See post #2 in this thread for the entries to do that.
If you don't want to cut / splice your factory harness, you'll need the adapter below, cut in half and use one side to plug into your harness and the other into your speaker. I haven't found a Metra equivalent, but this one works great...
I personally still enjoy the extra "presence" that the center channel provides vs having it unplugged, but with the low sensitivity of the 3.5" KS (88dB) it's no longer overbearing like the factory center speaker was. I listen to a lot of podcasts so the vocal clarity is nice coming from up top...

I'll post up a couple photos of my install shortly. I did a couple things differently that I felt were worth the extra work
- Slim gasket between SGS plates and the door to make up any variation in door
- Rivnut inserts in the door and M4 machine screws instead of the included coarse-thread...
I upgraded / replaced mine because the rear speakers were blown in my 2021. When I removed them they were heavily warped. The stock speakers, even the B&O, are just paper cones so I suspect moisture / heat played a role in causing them to be warped and I didn't want to replace them with the same...
The kicker KS are similarly sensitive (90 to 92 dB/W) and the silk tweeters sound pretty nice to my ear, albeit a little more expensive. The component 6x9 KS set also is a drop-in fitment for the 1" Tweeters in the A-pillar that come with the B&O system.
