Ok in my 1989 GTA I just removed the old factory speaker (i believe) and replaced them with some nice aftermarket speakers...also when i first got the car around a year ago i had to pull my factory stereo from my 1991 firebird and put it in the GTA...

Now i nv got sound from the back speakers and when i put the new speakers in i have good sound from the fronts which had worked b4 (crappy but worked) but no new sound from the rears...I think the plastic connecter is not the same or something??? I looked behind the stereo and there is like a loose black and orange wire in a plastic connecter that dont have anywhere to connect to but im not sure if these are to the rear speakers???

Can anyone help me in my confusion and tell me what i need to do to get this fixed?

 

Go to Best Buy or Circuit City and tell them what you told us, they'll know which wiring harness to sell you. You'll have to connect a new wiring harness to ur car's factory wiring to match the stereo you put in there.
