A car audio experiment I'm working on (please help)
Ok I believe this is pretty straight forward, but I do not know enough
about audio to know this will work. I have an aux. port in my car so I can plug an outside device to play through my car speakers. Then, because I had a spare cell phone hands free set, I had the bright idea that I could cut off the speaker at the end of the cord, and attach the proper sized plug (headphone jack) to go into my car. I have tried to do this (w/o solder) and it did not work. Im guessing it is because I need to solder my connections, but I dont know if I can go to a huge audio system from my crappy cell phone. If anyone has any ideas on this, please give me some feedback. thanks |

Try connecting just one loudspeaker lead and put an earth on the other input pin and see what happens (make sure polarity is correct.) You will also need to select the input on the radio (?) or if it doesn't have one then there will be a control line that will need activating (usually by application of an earth) to make it switch to the aux input. -- Woody harrogate3 at ntlworld dot com |

Im not talking about anything fancy really, just a run-of-the-mill POS mini jack (from my phone) -microphone-to a little speaker for my ear handsfree kit. Not an official car phone holder or handsfree system. I'm basically gonna jerry rig the thing so i cut off the speaker that goes to my ear. now i have only the plug into the headphone part of my phone and a mic with a wire after the mic with 2 wires (ground and a signal) I want to replace the speaker that wouldve gone into my ear with a male headphone jack that can go into an aux port, meant for ipods and whatnot, and use my car speakers instead of the small speaker for my ear. so im just messing around, but i dont know if this will work or if its necessary to use solder to work properly |
