Adding an MP3 plug-in to your Radio

I added some resistors in line with my wires and lo and behold, I have GREAT SOUNDING MUSIC (The mp3 player was overdriving the circuitry and the resistors worked like a charm!) …..only on the passengers side though. 😕 My soldering skills aren’t as good as they should be and one of them broke off. No worries though. I will re-solder everything in the morning and put the finishing touches on it!

Thanks to lewismug we now have a write-up on how to add a input jack to your SC-816!

Well, I took out my DMM (digital multi meter) today and took the stereo apart. I found the right and left contacts for the tape deck and soldered my wires on. Connected up a 3.5mm jack and plugged everything in. Turned it on with a blank tape in the deck, turned on the mp3 player and have sound! There is a problem though. With the sound as low as it would go on the mp3 player and the car stereo at half throttle, everything sounds fine. Turn up the stereo or mp3 player from there and everything is distorted. I’m assuming that the mp3 player is overdriving the circuitry in the tape deck side of things and causing it to distort. I will try to put a few different value resistors in line with my mp3 connection and see if that calms things down a bit. Maybe if I can reduce the amount of energy going into the board from the mp3 player, then it will sound better. I have taken pics of the connections to solder into so far, so if any of you want those, let me know.
