I have a factory stereo in my 2004 Grand Am. Neither of the back speakers work anymore?

I really think you should go to www.reliable-store.com they have got books on every vehicle and also how to service/repair it, parts info, wiring diagrams, electrical diagrams, fuse diagrams,
error codes, etc everything

You need the code number.....or perhaps a dealership can help you....

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.
Best Manuals

it should be written cast on radio for wire purpose
orange wire is there for ignition current turn on and off radio current
red for battery current (keep radio setting,clock)

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money

Here ya go. enjoy!
