I finished hooking up my amp and subwoofer about 2-3 weeks ago, and the amplifier is only ran to the sub. But for some reason now I get no sound from my rear speakers. I am hoping that they are only blown (at worse). Any suggestions to what it might be.

 

Are you sure the wires coming from the HU are connected to the rear speakers?

 

I ended up running all new wires to the rear speakers....along with installing Alpine Type-S speakers
