I am about to upgrade the original speakers in my 1987 735i for something a little more modern. I like the arrangement of having 3-way splits up front and 2-way splits in the back, so would like to keep this arrangement. I'd like any advice from anyone who has replaced there speakers. At the present I have a Kenwood radio/casette and CD stacker (no amp), but am thinking about getting a newer / better head unit, most likely a Blaupunkt of some sort. I would like to avoud having to put subwoofers and amps in the system and clutter up my boot. Thanks for any advice you can give me. Craig 1987 735i 152,500km
