1997 F-150 elec shorted speaker

;you will always have a continuous poser drain to your radio due to thememory in the radio. It is not much to worrry about. If your battery is draining down at night then it's something else and you can go to DIY section on here and see how to check for a draw on the battery other than the radio. Asfar as the crackling speaker, it's probably broken and sometimes you can reglue them to hold it to work right. Otherwise its just a replacement and you can get pretty much a matching one at any place that sells radios.
