Bose rear shelf speakers and sub stopped working?

[stapo69]

I have he full amped 10 speaker Bose set up in my 1998 S4. Just noticed yesterday the rear shelf speakers and sub have stopped working but I still have the front and rear doors working.

They all worked before and I have the correct ISO connector to run it all properly.

Cannot see why just these would stop working but not the rest?

Any ideas anyone?

Has the full amped system, so wouldn't hve any sound I don't think if the amp was not on, even with the original headunit in they don't work, gonna go through the amp pins and speakers later and test em
