Usually what causes this fault here is a fault with the sound amplifier (if equipped as most are equipped with this sound amplifier) or an issue with the radio itself internally.The crackling sound you have described here makes this sound more like the sound amplifier itself at fault needing replaced.I have had to replace several of these before in the past for this type of fault here.I have also had to replace the radio in some cases but I suspect this is more the sound amplifier itself at fault needing replaced.
This will have to be checked into further to locate which component is the cause here and then from there replaced.
