Making progress! So a few years ago I removed my dead navigation drive under the passenger seat and made these jumpers to allow audio to go to the front left speaker. IIRC the nav drive had an interrupt in it for that speaker only.
I must have bumped this while pulling into the OEM amp and backup computer, because I got audio out of the left front while playing with it. I don’t know if I’m missing something to control the left rear or if it’s been out for years and I’ve just never noticed.
Unfortunately, karma struck and I blew a fuse somewhere while playing with that same nav drive connector so I’ll have to track that down now. I might still just run new wiring if I can’t figure this out.
