I have a 92 Classic with the a/d/s system-your 95 has harman / kardon? Mine has a large amp in front of the subwoofer which drives only the sub-In the front doors, there are individual amps for the speakers in that door. Finally, I think the roof rear speakers are driven by the main stereo unit. Maybe yours is different, but I doubt it. My 95 4.0SE has 5 amps: 1 for the sub, and then one in each door to power the 10 speakers. If you lined it in, it would have to be to each amp. The only option (maybe) is to use the CD cable as an input at line level-you would have to splice the two channels into the left / right line in the CD cable. Then, the stereo would still be playing CD's but the sound would be from the MP3 player. That would be the best fidelity. Easy solution: Buy one of those tapes with a headphone jack that can plug right into your MP3 player, for like $10-20. (The kind that come in the "car kit" for CD players) I bought one at Radio Shack and the sound quality isn't bad-but only if the mp3 recording is at 128k.
