13 speakers in Infotainment 300 – where?

Hello dear Saab – municipality! I call for about 1 month a 93 Vector in Jetblack my own and am actually very satisfied with it. I wanted to see how it looks with the 13 loudspeakers, which should be installed at the Infotainment 300 plus, but could not discover by far 13! 2 subwoofers should be there, where are they mounted? Finally: I plugged my ipod times over a jack plug into the Aux input in the center console; quality was rather nice Laughs and the sound is very quiet – does any of you have experiences? (Will the result be better if I use Icelink Aux?) LG from Vienna Fabrice
