My head units audio works fine when using the on-board amplifier with sound going through the harness but when I use the RCA outputs with an external amplifier, I hear the sound of what's playing for half a second and then the audio stops. The power to the external amplifier is on the entire time. Please help

Sort of the same problem here .
I have an external amplifier. The amp is permanently connected to battery and the on/off sholud be controled by the AMP-CONT wire from the Joying head unit. The problem is that there is no control signal present on the AMP-CONT output wire.
If I instead use the ANT-CONT output wire it works fine, the external amplifier is switched on.
What is the problem with the AMP-CONT line, is there some configuration needed?
