I believe that it has bose "black gold" or something like that. I also believe that it is a complete replacement. You can verify this by pulling a speaker and seeing how much resistance they are. If they are less then 2 ohms then you should replace everything.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.
