I had Panasonic CD/MP3 head unit installed in my 2002 SL (instead of a plain radio) and now consider to replace front speakers. So there are 2 questions: 1. What are specifications for OE speakers (frequency response, RMS power range, peak power handling, impedance)? 2. How to remove front doors trim to get to speakers? I looked at Chilton's and Haynes repair manuals, but they cover only thru 1998 or 1999, and their front door disassembly procedures do not seem to be applicable to my 2002 SL. Thank you. Jerry
