Standard Audio System
Have xDrive23d; great car but badly let down by standard audio system.
Before deciding on upgrade options I would like to know exactly what I currently have.
The standard radio (UK) is the "Professional" which I believe outputs 4 x 25 watts. However I have the "Business Advanced" Nav System (606), thus whilst I do not have a "Professional Radio" facia, can I assume that I still have the same "professional radio" backend, ie 4 x 25 watt channels?
Secondly, the standard 6 speaker set up is 2 x tweeter/mid in the front doors; 2 x mids in the rear, and 2 x subs under each front seat. Am I correct in assuming that 2 of the available 4 channels are each driving not only a door mounted tweeter/mid but also a floor mounted sub, thereby leaving the remaining 2 channels to each drive the small, ineffective, rear speaker?
Perhaps one 25w channel trying to drive tweeter/mid/sub explains why the resultant sound is so lacking in depth.
