Cherokee new stereo

I have power and the left front speaker but cant get the other to work the waires arent the colors they should be I have a white tied to a green for the front left im stuck any help would be great.

I'm a bit confused by your post. You have power to the radio and sound comes only from the left front speaker?

Did you just replace the speakers or are they still the originals?

Make sure your balance and fader controls are centered.

make sure your connections are good, and that it's all balanced, I'd just rewire the whole thing with some really good thick stuff, doesn't take to long and it'll probly improve the qaulty
