Hi, I’m still breaking my head! I bought a BOSE sound system for the Omega B. There were now 10 speakers with. 4 tweeters, 4 midrange drivers, 2 bass drivers for the storage. When demotizing my speaker I now have to find out that in my car but only 2 speakers are installed instead of 4. Therefore the following question arises: Does the series sound system have only 8 speakers or 10? Are there 2 different BOSE sound systems? And anyway, why are there people?
