Random is truly a difficult problem to solve, if no pattern of failure can be detected. It sounds as though the alarm may be at fault. Is the alarm on and set to radio, CD, or beep? If radio, that could pinpoint the problem. If you have another, mechanical alarm, use it for a couple nights with the Bose Wave alarm off. If the Bose still acts up, then it isn't the alarm. Try unplugging the unit, waiting at least 30 seconds, and plugging it back in, which will cause you to need to reset the alarm. Alternately, remove the Bose cover and blow out dust. I find the Bose susceptible to dust as a cause of malfunction, which may point to the cause being the compact design of the unit. Good luck.
I have the exact same AWR1-1W model for repair last week. I am assuming you have a meter and you also have soldering skills here.
You might want to check the Q4 transistor (2SC3792) for a short on the two outide pins. With the power disconnected, measure with a multimeter the resistance between the two outside pins of the Q4 transistor. If you measure anything between 0-3 ohms it is shorted. Replace this part with a similar part or you could replace it with the new Bose recommended part - 2SD438F-MP-E but it is very hard to obtain. I have used an 2SC2655 instead and had no problems so far with the radio. This radio also came in totally dead with no display nor the radio working.
If you disconnect the bose radio, it loses it's programing.. Needs to be taken to a GM dealer and vin coded. as for the volume knob, it's digital.. if it's not working it wont be a connection issue, it's likely a flaw on the board. The best place to get that fixed is United radio in NY. 1-800-448-0944
If your remote worked everything for a few weeks and then quit, and you are sure the codes are correct, take the remote back under the 1 year replacement warranty and exchange it. It is defective.
There's a line fuse inside the radio, mounted on a PC board. CAUTION:
disconnect the set from power before opening the case or poking around
inside. The fuse could be bad, but these sets are notorious for losing
the power transformer. If the fuse is ok then you are looking at a
$100 repair fee from Bose. You might want to check out the new HD radios -- better sound, MUCH lower price.
Had the same problem on the same machine 15 or so years ago...took it to the Bose factory shop in Framingham (or real close )Massachusetts, and they fixed it in 20 minutes...cost around $50...at the time they said it was a real common problem, and an easy fix.
If you're saying you hooked the Bose speakers directly to the Yamaha's amp instead of the prescribed way through their own bass module - they're cooked.
Unfortunately Bose will not release their schematics or parts lists, effectively giving them a monopoly on repair of these sets. Before you spend
the big bucks on repair or a Bose "upgrade", you might want to check out the new HD radios.
Better sound and MUCH lower prices than the Bose.
