Okay.
My Bose system is completely stock, i mean completely. I start my car this morning and the system wont work. No crackling or static or anything, just no power to the core system. I took it to the shop and they said that they could trace the power to the back of the system, and that all the fuses were okay. I'm pretty sure it's dead, but any suggestions would be greatly appreciated. Thanks!

Check this --->
The Bose head unit drives a relay that in turn turns on the bose amps on each speaker.
The relay is behind the plasic kick panel on the driver's side. If you turn the cd on and off (if you have one you will not have the antenna noise) or use the radio. You should be able to hear a clear "click" of the relay switching. If you don't hear it, the turn on circuit in your head unit has probably failed.
You can bypass this by foring the turnon lead of the relay to an "ign" or "acc" +12 volt source. This way your Bose amps are always on, whether the radio is on or not while the car is running. They will be off when the ignition is off so they won't drain your battery. If this is what your problem is, you can get a lot of extra life out of the pieces you have for a zero cost modification.
If this is NOT the problem, you will need to do a much deeper root cause search. If you want to replace Bose pieces this will minimize your cost by only replacing what has broken. If you are ready to upgrade to something better, this may be your cue.
Good luck,
John

Head unit Fuse
Also,
There is a fuse in the head unit itself, so if they just checked the panel fuses, they didn't do enough. This fuse blew on mine when the battery was reconnect, with the radio on.
Pull out the head unit and check the back of it for the fuse.
I am sure that there is a site out there that show how to do this. It is not hard. 8 screws to remove.
