rear speaker install question

[Sprey]

Been doing that, even ran a jumper to ground from the ant. Any idea what the blue wire is for since I guess out ant is not powered?

Hmm our stock antenna does have a little blue wire that runs up to it, just like a powered antenna, but of course for our one it is to get a stronger signal?
i didnt have mine connected at first then realised what it was so connected it and the reception was much better

The manual says the blue wire in the connector behind the radio isn't used. Maybe it's just there for use if an aftermarket power antenna is ever installed?

At the antenna location/connector(s), is there just a blue wire and an antenna coax?

Yes there is but it's not hot.
