Speaker problems

[Arturs_L]

Hi, I have 2006 Octavia with 12 speaker system. Front driver door bass speaker started to rattle, it was blown, but it still working. One day all of bass speakers (in all 4 doors) stopped working. Now I have error 00872 and 00873 for open circuit in both of rear bass speakers. Can it be connected with blown front speaker and replacing it will solve my problem or is it something else?

Is it a Bose system?

 

I'm sure the Bose systems operated with an amplifier so that could be at fault 

 

It's too coincidental for both to stop working at same time for it to be the speakers or door wiring at fault. So my guess is sterio or amp

In my car data sheet it's only written - Sound system, 12 loudspeakers, digital equalizer. Radio - audience. No any signs about Bose.

 

Quite sure that it's not wiring fault, because rest of the wired things work, and not really using back doors.

 

Strange thing that none of bass speakers are working, but fault is only for 2 of them.
