Has anyone else had an issue their factory stereo system? I seem to have only 1 speaker that works out of 6.
I'm open to ideas and suggestions.

 

What class truck is yours, and did it come with a stereo package like bose, infinti, or rockford? do you listen to the stereo at high volume like 75% or up? stock stereos are pretty cheap since the factory wants to buy their nonessential parts at lowest cost, so they tend to short, or wear out, or maybe even your speakers could have worn out. either by overheated voice coils or busted cones. Also could be a disconnection in the wiring. but with trucks like yours a 2008 the wiring is a nightmare so lets hope its not that.
