Speakers not working..., WTF?! Options

[Diab1o_3000]

I recently got my celi back from painting, and now my speakers don't work. I've already called the shop, and he assured me that touching stereo systems is a MAJOR taboo and they don't do it. I took my faceplate of course, and it IS working, but the speakers won't even hiss at full volume. No signal at all. He is a friend of mine and my dad's so I know he wouldn't do anything like that. All of my speakers are actually there and they are all still wired up correctly, so wtf? Is there a fuse somewhere that just controls the speakers? Any help is appreciated.

Did you solve your other electrical problems? This could possibly be related.

I have to ask my cousin in the morning, but I'm pretty close to positive that I tried the stereo before I even started installing the gauges.

first check your interior fuses..

then check the plugs beneath the driver side panel. one of the harnesses are for your speakers. it's the one that comes inside the cabin from the door.

My fuses seem to be okay and I recently removed and plugged back in both door panels, so I know the wiring is okay, and I don't have an amp. Just an Alpine unit and 4 Alpine speakers.
The guy at the shop is supposed to have his stereo guy look at it on Monday morning. I just wanted to know if there was anything that I could do in the meantime.
Another question: Do speakers run in series? because that would at least set my mind a little more at ease to know that it might just be a wire on one rear speaker. that shook loose. I can't see how they COULD run in series but it's worth asking.
