My car audio recently went out... I think it has something to do with two cables in my trunk touching (there were formerly subs in there). The head unit gave off smoke and the speakers started popping until I turned them off. Now the head unit starts up and looks like its working fine, but no sound comes out.

I'm not much of an audio guy, i just wanted to know what you all thought i could do to fix this and just get me back some audio. Anythin ya'll can recommend to help, I'd appreciate it.
