You know, I'm not a mechanic, just an enthusiast...sort of like just a few of you! I've been in a 3 since '94, so have picked up a thing or two, but most of my learning has been here and on my e46.

All you have to do is take my advice...read diys until you puke. Simple!

Yea, both left doors have a speaker working.

Okay, so the preamp channel send is working.

I don't know what 'open common connection points' means, though I can certainly jump from a working speaker into a non-working one...but I don't think it's the speaker and I know it's not the entire channel.

"Opening" (disconnecting) connectors in the harness/speaker path while testing may reveal something grounding the output. "Common" points would be speakers wired in parallel, on the same channel, where both share the same cross-over point or amp output. Example - all left, mid-bass speakers. Solve for one zone at a time. Find the output send at the amp for left front mid-bass. Isolate the connection +/- pair and insert a test speaker at the output. If it works, test along the path by inserting your test speaker and disconnecting the car speakers at any point you can disconnect without cutting. If you can make-up a long, by-pass jumper pair that allows you to play the front speaker (injected into the local speaker connector) from the rear isolated output, then your harness has an open or ground.

So a wire hitting ground could coz the amp to shut off that one speaker?

No, that would be shut off the channel killing all speakers wired in parallel to it.

You're right that it should come out from the body not the door, been a few years since I did one, should disconnect in the foot well area and push out, you pull it into the door then you can manipulate it much easier with door panel removed.

Since it's both the door speakers and the rear package shelf speaker, I think it must be the amp.

You have a similar issue?
On mine my drivers side quits playing sometimes. I hit the dash one day (out of love)
and it came back on again. Mine doesn't go off again when you re-power the radio but randomly
or maybe from road bumps. Then I noticed it ONLY does it when the cd changer is playing.
So I think its probably the connector going from the changer into the head unit.
I'll check it eventually to see.

Maybe your issue also???

ALL of my speakers just went out all of the sudden. Here's my situation: I have a Dynavin head unit. I have an external amp and subwoofer. My subwoofer still plays bass frequencies when tuned in to the radio... it's just my door and shelf speakers that do not play sound. This means that my aerial amp is still good because it is providing signal, right?... or else my subwoofer wouldn't be able to pick up the bass frequencies...?

I took my dynavin out and inspected all of the connections... nothing looks bad. Oh, and even though I didn't think my aerial amp was bad, I still gave it a look... nothing looks bad there either (at least visually).

Any advice?
