The power antenna wire only supplies 12vdc when the radio is on. When CD or other sources are selected, the power antenna wire goes to 0vdc. The remote turn-on wire provides 12vdc whenever the head-unit is on. If your amps are powered on only when the radio is turned on, I would bet that you have the power antenna wire connected and not the remote turnon wire.
