|  Pioneer SX 424 Speaker Polarity | NCMike Apr 13, 2001 7:29 PM | | I have a SX 424 and the speaker plugs are missing. I plan to just use spade terminals to hook the speakers up. Does anyone know which hole is the positive. It has a vertical and a horizontal slot where the plug went. TIA Mike |

Unless someone can tell you for sure, here is the conventional method most use. Hold a 1-1/2 volt battery cell between the two wires. Whichever wire touching the positive terminal of the battery causes the woofer cone to move forward should be connected to your red connector. Sound ok?
Good luck

|  Disregard myprevious response, I mistook your question to mean.. | Lefty Apr 13, 2001 8:41 PM | | that you had speakers with unmarked wires. Receiver output wires is a different challenge and of course the battery trick won't work ;-)
Most any receiver design I have seen has the negitive side wire grounded to circuit common, so if you have a multimeter you could just find which speaker output wire is grounded by measuring each output wire, in ohms, to one of the RCA plug outside shell. The one that reads 0 ohms is the minus terminal. Hope that helps.
