Heres a strange one ref car radio/cd player.
You have wired it to the wrong remote lead. there is 2 blue ones, one for the amp that is live all tge time when the unit is on, and another that comes live when you select radio only, which powers an electric aerial.
To confirm it, turn it to cd, then turn the traffic announcements on (ta button). You'll find the amp will come on!
