Wire diagram for amp/speakers?

Does anyone here have the wiring diagram for the amp/speaker's? My left/rear door speaker is not working,and I would like to diagnose the problem if possible. Any idea why there's no sound...or is there a fuse for that specific speaker?

Try this. Time to go aftermarket speakers/subs and amp. If you do decide to go that route, let me know. You will need AudioControl LCi6. It sounds awesome btw.

Thanks for the info. I tried looking at that diagram. But just can't figure it out. I'm basically looking for the rear left door speaker/tweeter wires that goes into the rear amp? Can you pin point me what those wire colors are. And which connectors are those? Thanks!

See section 1e of the schematic. Speaker wire will be brown/green On negative side and Solid green on positive side. Tweeter will be section 3l, wire color green on positive side and Brwn /green on negative side.

Amp should be on left inside the trunk. Another way to check your speakers is to adjust fade/balance to that speaker listen for anything abnormal. If you hear a scratchy sound your speaker is more likely shot.

I know where the amp is. It's the connector that I'm looking for? The previous owner had an aftermarket amp/speaker system installed. And I guess when they put it back to stock.the wires got mixed up. I did the adjustment to that specific door speaker.but hear nothing. I thought the speaker might been bad.but it was working when I tried to switch it to the other side?
