Not too familiar with this cars because it's my partners and we rarely have problems.
About 2 months ago all the door speakers stopped working at the same time, tweeters are all she has left.
I replaced the crappy headunit with a brand new Sony xav and still, no door speakers?!
Electric windows and door locks all work as normal, any ideas?!
