just fitted a new stereo in my car, but I'd cut the old aerial plug off (cos I needed a male connection, not female), therefore just having a wire with no plug on the end. I've bought a new plug, that basically crimps on the end of the stripped cable. I'm now getting a crackling in the background of every station. Any help anyone? Also, I get no AM reception. Although I didn't get it on my original stereo anyway. Cheers!
