| AUX input trough CD player |

Hi. Just a random tinkering project. I want to use a car radio as an amplifier. Need to get audio in somehow. It has a removable CD player. The connector pins have left and right channels (and s-ground which is for audio input too I guess?). I wonder if there is a way to trick the radio so it stays on CD play mode and lets the audio trough. Ideally to work without the CD player attached. Would free up space for a power supply. Any pins to connect or something like that? --- End quote --- |

An easy way is to keep the CD player attached with a CD in it. Then you switch the audio pins to your Aux. I see that there are two Bus pins. (Bus- is also Gnd) Presumably this is used for the CD player and radio to communicate and let the CD player tell the radio that it is playing a CD. You should investigate what is transmitted over this bus. You can then program a microcontroller to send the same signals. Do you want to keep the radio function? You could also wire the Aux in between the amplifier section and radioreceiver. May be add a switch or relay to keep both functions. |

No, I don't think I would use the radio. Will have to investigate that option. Thanks for the idea. I think it also has a connector for tape player on the bottom. Maybe it is "less digital". Working with microcontroller would be a bit too complicated for this project tho. |

What car radio is it factory or aftermarket, I made an adapter for the one I have in my garage. Once the radio sees that there is power going to the CD player it will pop up when you turn it on. --- Quote from: KrisBendix on September 29, 2018, 08:47:30 pm ---Hi.
