car speakers?

Chevy Suburbans are equipped with a Bose system. I recently yanked the Bose out of our Suburban and replaced it with JL Audio amps and Sub, Alpine head unit, and MB Quart Speakers -- HUGE improvement. I also added XM radio. Alpine Head Units come with something called a "MEDIA EXPANDER"
which is meant to be used with MP3's and XM Radio to fill out the missing pieces. I am not into MP3, but I can say that the MEDIA EXPANDER works really well with XM radio. Here's another thing -- instead of a CD changer -- here's what you do; The new Alpine Head Units will interface with an i-pod, taking over its functions and keeping it charged -- THATS THE WAY TO GO!! With a 40 Gig i-pod, you can store about 150 CD's UNCOMPRESSED. That's better than any CD Changer -- PLUS -- the i-pod is portable. Don't bother with a CD Changer, use an ipod -- it is like having a 150 CD Changer.

Go Dynaudio! I had Boston Acoustics and IMHO their tweeter was very harsh. Dynaudio uses a soft dome and is very smooth. As my car stereo has improved (Theta Basic IIIA, 9 jitter filters...) the Dynaudios have never been the weakest link. They are very reliable. I have a 3 way set that I have used for 8 years with no problems.

Anybody know speakers that can be used in the BMW 3 series. My local installers have all told me you have to go back to the dealer to get replacements. I want to upgrade as long as I am replacing. I know nothing about it but the main rear speakers have this strange 3 wire connector. Help! please! sorry if this is a threadjack.

Mechans, I'm working on my 325i. It's a challenge...

Mechans, which year/version 3 series do you have (E36, E46, etc)? Check out roadfly.org, & do a search, &/or ask your question there.....I'd also like to know as I have a friend with a '93 318is who's looking for speakers.
