Okay so I installed a cd player on my 88 Trans Am the other day and it worked perfect just that i couldnt get the back speakers working. So i wired them up last night and installed them and they worked perfect. As I was driving last night I hit a bumb and all the speakers went out and I couldnt hear anything. So Today I decided to re-connect everything just to make sure I didn't disconnect anything. Everything seems to be connected right I just cant hear any sound the stereo turns on but nothing comes through any speaker not even the front ones. Any ideas on whats wrong?

 

Hmmm. shorted out. Check fuse and replace. Check your wires make sure there is no exposed bare wire.

 

Your head unit could have just went down the toilet. if you have another head unit test that out.
