Radio

Ok so i fit 8 people in my lil civic hatchback and i was driving home and my radio wires started sparking and smoking and then that was it. The radio still played but there was no sound? to this day it still turns on and plays but still no sound. i tried using the other speaker wires and it still didnt work?? any ideas??? thanks!

Dont fit 8 people in a hatch? Only one I could come up with...but seriousyl, try swapping head units with another one (preferrably very cheap) and see if it works.
