You can check for broken wires if you can get the unit out. But unless you have the right test Equip. thats about as far as you can get. there could be a crack in some surface mounted items on board or the Amp. is dead. You just need some place that can really find the problem. ronm
You know what they say..the only good Bose is a dead Bose. But seriously, you'll probably need to drop it off at a place that specializes in such a thing.
I have a working Bose from my 97 that I pulled at 80k. If you think yours is really dead, you can have it for very cheap. Or if you'd like to go non-Bose aftermarket, you can have an extra DIN panel available if you buy a normal DIN headunit with a Scosche adapter.
Thanks for the advice, and I will check the fuses, but before I take or ship the head unit somewhere, is there any way I can distinguish between a problem internal to the headunit, or an external problem with the fuses, relays, amps or speaker?
I'm not an electrical expert, but if the fuses and relays look good I would try taking the headunit out of the dash but leaving the wiring connected. (Carefully) then turn on the ignition and stereo to see if there is power to the outputs using a multimeter. I'll bet someone with more stereo experience knows a simpler way. If you haven't taken the dash out before, you definitely want to find the directions first. It's not hard if you know what to expect.
I believe there are two amplifiers for the Bose speakers: one for the front speakers somewhere and one for the rear, mounted in the rear deck. These amps sometimes go bad, but since they're separate I would expect that they wouldn't fail at the same time (no sound at all)
Sounds to me like your Bose system turn on relay may be faulty or the trigger for it from the headunit went south.
The relay turns on multiple amplifiers for your system.

My 93 Maxima Bose radio went dead about 5 years ago. It is a common problem with this radio. Some componets in the power supply is the weakness. I sent it to a repairer in NY and fixed it for about $50. I will try to find the address for you.
Seth, I had a '97 that did exactly the same thing. Power would come on, antenna would raise and the LED would come on but no sound. I checked all fuses and even checked the relay under the driver kick panel but eventually sent it to carstereohelp

There was adefective board of some sort that was replaced for a little under $100.Once I got it back it was good as new. Much cheaper than buying a used oneoff eBay and definately a lot cheaper than replacing with a non-oem headunit and having to re-wire and re-speaker the whole car. Good luck.
There are several companies who make replacement boards for defunct ones for a Bose system. Any dealer who carries AAMP accessories can probably get one. Any aftermarket four ohm (not Bose) set of components would smoke the Bose system. The best way to fix a deaBose system is to remove it and throw it away. ACD head unit fed into a four channel amp feeding four coaxial four ohm speakers will sound better and last much longer.
The low-impedance Bose speakers might smoke an aftermarket amp. Four-ohm aftermarket speakers are unlikely to deliver full power or proper frequency reponse with the Bose amp, but how exactly would they "smoke" it? Bose amps can easily drive 4-ohm speakers.
