speakers stopped working

[blueskittle89]

I have a 2003 GMC Sierra 1500hd SLE. I currently don't have a front drivers side window due to an accident. I was in Wisconsin last night and I parked my car outside. When I got in the car in the morning, all of a sudden, none of my speakers worked. The radio info worked on all stations and it cycled the tracks just fine on the CD player. I have already replaced the radio and radio-amp fuses, and still absolutely no sound. The chime also does not work when I turn the truck on. I have already replaced all the speakers with Pold Audio because half of them did not work when I bought the truck.

 

Any ideas on where to go from here???

 

Thanks.

Check for power at the speakers first. If you are not getting power there, then kept following the wires up through the system to see why you are not getting power. Quick and vague but this is for starters.
