802 series2 no sound whatsoever PLEASE help!

Do you have a digital meter? They are quite inexpensive and indispensable for electrical and electronic repair. You could try the usual methods of measuring the resistance across the input, check each speaker, etc. Sounds like a simple discontinuity in the signal path. It could be just one speaker if they are in series, etc (like Christmas-tree lights).

Yes, I believe they are a series / parallel arrangement of the 8 speakers. It's been years, though...
Best,

IIRC Bose later went to 9x .9 Ohm drivers in series to reduce cost. One open voice coil and whole string does dead, just like old christmas tree lights.

Original ones were series/parallel, that is why they used 9 drivers so impedance came out neatly using 3 strings of 3 drivers each.
