hi, just got my self an 735i, and found that the audio in the car is sh***. i won't to change the speaker's but can't find out what size they are, so if any one who's had an 7 series and changed the speakers pls let me know what size they are.

Keep us posted on what you find out. FWIW, my new one sounds much better than the e38's did.

You don't buy a BMW for the radio...turn it off and listen to the engine purrrrr!!!!:buttrock:buttrock:buttrock

You might be able to directly replace with the components from the Logic7 system, which sounds very nice IMO. Not sure though.

My two boys (13 and 17) love to hear my open it up a little. It puts a smile on their face too. :D

i agree with everyone here...turn it off and hear it roar haha

I like to hear it rumble when I start her up (Magnaflows), but after that, the only thing I wanna hear are my tunes bumpin'!
