Loud noise when i turn on radio

When I turn on the radio in my 1995 mazda 626 there is a loud sort of grunting noise in the rear of the car. The antenna does not work and I can either keep it up or push it down manually. I think that the noise is related to the antenna not working. Any idea what I can do to stop the sound? I don’t have any particular interest in getting the antenna fixed.

Thank you.

Cutting the wire to the antennae will bring peace and serenity.

Don’t cut the wire. Simply unplug the antenna connector. BTY, a used antenna assembly is about $75 bucks.

Where can I find the antenna connector and how can I be sure that I am not unplugging anything else? Thank you!

There should be a power connector to the motor near the antenna.
