As per the title.......why?
I have a new stereo for the car and thought I would check it works today. The connectors are the same as the old one; previous was an Alpine aftermarket and new is a JVC, but I don't have an aerial extension connector so thought it would be OK. I couldn't get the new one to power up. So I plugged in the old Alpine and with the aerial connected it works fine but without it won't fire up either.
The weirdest thing is that with either connected and the aerial unplugged, there is a constant 'clicking' from the PCB in the nearside footwell speaker.
I can't see how the aerial has anything to do with power to the radio, as it has it's own earth.
I hate 12v DC, it doesn't make any sense to me!
