Hey guys new to the forums here and just bought my 1998 BMW 318TI about a month ago. Already in love with it. A few repairs here and there since purchased. What's really bothering me at the moment is the rear drivers side speaker in the hatch. I have bought a new headunit as the one in it prior was an old sony and was broken. I have a nice Alpine in there now that works perfect. So i decided to start replacing the speakers as i like to hear nice loud crisp music when im driving. I got the right side rear replaced, then did the left side today and it doesn't work at all, no sound. I fiddled around with it for about an hour wondering what could be wrong. I'm stumped and not sure where to start diagnosing as i've never had anything go wrong during the installation of any audio. Any help would be awesome. In included a pic of the setup. Glad to be on the forums!
