I'm putting a new Pioneer stereo system into a 1999 Mazda 600 for my friend, and for some reason, the speakers are not working at all. i have hooked up plenty of stereos before, and have never encountered a problem like this, it's weird. Someone please HELP!!

 

Yea I have a Pioneer radio that the speaker wires comming out of the back of the head unit do not work. For some reason they just don't work they did at one time, but not anymore. You might try getting a new wire harness from like car toys or somewhere, then try hooking it up again. Thats my thought.
