Hi my friends, i'm new member and i have a question.

I have a Comand 2.0 for clk (208) and i put it in my 99 ml 430 that has the original Bose sound System.

I connect the rear cable A + B but sounds only the door speakers.
Sub does not sound.

Can you help me? I need a special connection? At this moment the sound came from the comand's amplifier or bose amplifier?

Another question.
I read that my sound system has 7 speakers but i see only the sub under drive seat and the door speakers. Where is the other two?

Please give me some information?

Thank you very much.
