Bose coding / speaker issue

[MrStranger]

Hello there.

Own april 2011 A7, with Bose sound system. At some point realised that some speakers dont work.

Symptoms/Problems: 1) using output test in obdeleven, front left/right midrange speakers dont work, front left treble makes noise on right side, front right doesnt make sound at all. Center speaker doesnt work.

However, using AA battery test on amp connector pins, every speaker worked except center speaker(only produced noise behind rear right passenger). 

2) balance/fade settings in MMI do weird stuff. They dont balance as reflected on the screen.

3) Had software management code, 03276 in 5F module. Cleared it using adaptation. 

4) Module 47, speaker module, showed "module not coded" fault. Module showed "long code 000000". No description of long code on obdeleven. When changed long code to 10000 or something fault disappeared.

Is my amp not coded correctly? Is my amp dead? Pls help.

Thanks!
