I had just installed a new stereo in my avenger, and everything works fine and it sounds great. The problem is when we plug in the antenna all the way into the head unit, we get a really bad signal. When we only plug it in a little bit, the signal comes in clear. At first we thought it was a faulty adapter cable, so we ordered a new one and faced the same problem. Then we took apart the head unit to see if it could be grounding out anywhere but it all looked fine. Anybody know how we could fix this? Any information would be a big help!
