  1. Julie, Unfortunately, it sounds like your radio is starting to fail and may need replacement. Hope this helps. Good luck with your 1999 Nissan Pathfinder stereo replacement.

  2. Can you please tell me why and how to fix my stereo cutting out randomly? Ever since it was installed it has cut out, and after i hit my dashboard a few time it will sound normal. When I say cut out I mean it will all the sudden sound like the speakers are blown or something. The music still plays it just sounds like crap. Then once I hit it a few times it will go back to normal. Please help me fix this cause I really am looking like an idiot beating my car as I drive. Thank you Julie
