mopar radio questions

In my experience indoor antenna gives good results only on FM. For the AM you may get one station and that's about it. I did not have an antenna hole so I used one of those magnetic base antennas used for some trucks and ran the wire through the crack between the door and the fender. Works great for AM. For bench testing you can use your + battery post for the +12V red wire. Make sure you ground everything properly on the car or the - battery post.
