So I bought a 2006 Subaru Legacy Wagon that had minor outer panel damage to both doors on the passenger side. Randomly found a dude scrapping a car of the same model and colour, but Few years newer and higher spec than mine and managed to change the doors over myself. However, after I changed the doors and fired up the audio system for the first time (stock audio system in Subaru), I discovered the speakers just in the replaced doors don't work at all. I definitely correctly connected the speakers back up before I replaced the door panels. Audio system in the wrecked car was a Macintosh. I also bought the speakers from the guy and tried those and they don't work either. I'm assured that the speakers worked fine in the old car before it was wrecked. Anyone know any simple reason for the speakers in the replacement doors not working? Would the wiring be different from one year to the next of the same model car and therefore not be compatible with my audio system? Cheap and easy fix for an auto electrician or na? Thanks for any help in advance.
