doing an install with an output converter ?

[jart27 10+ year member]

Hey gang, doing an install and got an rca problem. When i plug either L or R into the amp it plays ok, but when i plug both rca's in amp wont play. never had this prob and dont understand why it would play if i had a wire wrong from installin the converter. Any troubleshooting ideas?

Thanks, Justin

Is it that i may have switched a positive or a negative in one of the channels which would make the signal not run parallel

If you are using an LOC to convert L/R speaker outs to RCA for a sub amp that is bridged, then if you have *one* of the speaker connections swapped it will only work when one RCA is plugged in but not both - this is because the L/R channels are out of phase and cancel each other out. Double check your L/R speaker wire connections to the LOC.

ya sure enough, had a white to white and the 2 were switched. schematic was right, just somehow twisted the 2 around.
