I would like to connect the purchased internal antenna to the no name of the radio. Could anyone suggest how to connect the amplifier power supply from this antenna? (red cable in the photo). I know that the black coming out of the amplifier is a minus and it should be attached to the body. The radio has an entrance for one cube. Can I plug in the power supply there? 
Edit. After connecting the red cable, the LED of the amplifier lights up. The problem is that connecting the ground to any part of the body does not do anything at all. On the radio, you only hear dull pops at 5-second intervals.
