Okay, I have factory sound system with explode cd player. My deck works just fine, but no sound out the speakers. All wires have been double checked. Speakers work by themselves. Is there some way the harness is bad? I have intermitent sound when I hit a bump in the road. I have check deck and it works and I put in another deck and it has the same problem. Any ideas? I checked grounds and all. I checked constant power, swithced power, grounds, speaker wires. power ant/ amp wire. WTF

 

hmmm color of the speaker wire get mixed up? you could try a new wiring harness....

 

sometimes when one of the speakers are f#@$ed it causes the rest of the speakers in the system to shut down or not play at all. Look and see if one of the terminals is touching the chassi of the car or if one of the speakers is blown. you can check it by pushing the speaker down, if it makes a raggedy tough grinding noise, it's time for new speakers. hope that helps

 

I have new speakers. All pioneers. With sony craplode deck. I think I'm just going to run all new wires, basiclly make my own harness. hate doing it, but I can't find any thing wrong.
