raptor 2023 f-150

Hi, there is a weird sound like crunch when put the gears from park to reverse. It’s brand new 2023 ford raptor 600 mile on it. Any ideas?

I am not liking the B&O sound system that came with my 2023 truck and looking at doing the lower diagram, any comments if anyone has had experance with these products? It seems there is a "T" harness that might not be shown but i am planning on running new speaker wires for the new speakers...
