/* ---------- "Wiring of Chrysler AM-FM radio - 19" ---------- */
I have a 1985 Dodge Charger with an AM-FM radio, and I can't figure out
what all the wires runing from the back of it are for. I've put in a tape
deck, and a switch that allows either the radio or the deck to output to the
speakers. When I rotate the fader switch on the radio to the read speakers
(I think, it might be the front), I get a terrible noise out of the speakers,
kind of a fast, low-pitched, rumbling noise. I also think I'm not getting
full volume out of the radio. If anyone knows what wires go where, I'd
appreciate hearing from you via uucp mail. Thanks in advance.

Sorry about that last response. If you have it set up in any way shape or form that creates a common ground you will get this noise. I think I remember trying to figure out a tape radio switch for a four way (not to be read quad) and the only thing tnat was possible was two switches. Just not enough terminals on standard dpdt type. Each line has a floating ground that run from the output to the speakers. This more or less lets them get more sound for less power (more or less). The final deal is that if any of the lines wind up having a common (as opposed to floating ground) it's don't work too good. This is also the reason that the high powered equalizer/boosters require seperate lines for each speaker. Actually the left and right side must be seperated, the front back fader can have their (-) side tied together, however the + sides must be diferent (of course.) Well I don't know if this will help any, but perhaps give you an idea of what needs to be.
