Guest dwhiteside64 Posted April 17, 2015 Share Posted April 17, 2015 Do you have the service manual? The Sonomatic radio installed in my '64 Riviera has all the wiring connections, schematics, and drawings located within this manual. Not sure if this was the case during '57-58, but worth a look....

coupekid Posted April 17, 2015 Author Share Posted April 17, 2015 no ...the service manual does not show radio diagram ... a sonomatic photo fact schematic was issued but is not detailed to show where the speaker wires connect to... there are a fair few sonomatic radios for sale & non of them have speaker wires attached... this seems to be one of those tricky topics that even google has no answers to either...

Bhigdog Posted April 17, 2015 Share Posted April 17, 2015 (edited) As I remember, (big caveat there) One speaker wire is grounded and the other is a single pin plugin on the radio.Alright, memory does serve correct. I just checked out a spare I have. Looking at the radio as if you were sitting in the seat. The forward passenger side of the radio chassis is on a diagonal. In the approx. center of that of that diagonal panel is a hole with a fiber washer. The speaker wire pin plugs in there. My 57 shop manual does have a schematic, which shows one wire grounded and a one pin connector. But of course as a schematic it does not show physical locations................................Bob Edited April 17, 2015 by Bhigdog (see edit history) Link to comment Share on other sites More sharing options...
coupekid Posted April 18, 2015 Author Share Posted April 18, 2015 Thankyou Bob, good man ,, appreciate your input & efforts !!! ... i have used a single pin plug similar to the old 70`s headphone type end plug in that tiny socket you mentioned about & attached the other end to one of the speaker points..the other speaker point wire is to chassis frame.. there is a buzzing/crackling sound only coming from speaker which seems to mimick the valve radio buzzing sound but no radio station pick up.. antenna is plugged in .. am i using the correct speaker plug ??? ....it seems to fit well ..

Bhigdog Posted April 18, 2015 Share Posted April 18, 2015 A head phone jack pin usually has 2 conductors in the one pin. Your speaker pin is just a simple pin with a wire connected to it. If your speaker is making noise you have connected it. You could have a bad antenna connection or bad radio. ................Bob Link to comment Share on other sites More sharing options...
