Hello,

First time poster. I recently purchased a 1yr old 2006 325i. Nice car, but I was very disappointed that the rear doors did not have any speakers (only located in the rear dash..total 6 speakers). Honestly I didn't even check since I thought is was included with the standard system.

My previous 2004 325 coupe, which had the standard audio system, had 8 speakers (4 front and 4 back). After looking up the specs on the '07 328, it looks like the standard audio system should have 10 speakers and the upgraded Logic7 system has 13 speakers.

- Where there some early '06 models that only had 6 speakers?
- The receiver has a setting for Sub woofer, but there is non in my car...Does this mean that there is an output on my car where I could EASILY connect one and put it in the trunk?

- Any idea if/what the cost whould be to upgrade the speaker system and what would be the best course of action?


Any additionial info on the 2006 325i audio system would be greatly appreciated.

Thanks for any assistance.

Regards,
David
