ok so the only speakers in this car are in the dash facing down. i checked out the wiring on the right hand side. the righthand side speaker wire was connected to a black plug which lead back into the car. at this point the left speaker was only working.
Then i saw a wire coming from the back of the car with a wite plug just dangling there. So i unplugged the speaker from the black plug and connected it to the white plug(which was dangling there).
So then both speakers worked!

yay!
But then i noticed the light behind the speedometer wernt working. so i switched back to the black plug and the light behind the speedo worked again but only the left speaker worked again!
Im new to this....whats going on here??
PLZ HELP
much appreciated
