Hi everyone, I recently replaced all the speakers in my girlfriends Cherokee and noticed the front driver speaker not working, I looked it up and saw it’s usually a broken wire in the door... low and behold the speaker wire was broken within the door boot. I butt connected the wire but the speaker is still not working. The speaker harness has a positive (green) and a negative (black with red stripe) but on the car side I only see a green wire, where do I connect the negative cable? Also after doing this the driver side door lock button only works with the car off. Any help is greatly appreciated
