Hey I have a 02 oz lancer and i wanna know on the doors which wire would be negative and which would be positive for the speakers..
How about the back too? Does anyone know what size the speakers are on the back?

 

Not sure on there polarity but there 6 3/4 speakers but 6 1/2 fit !
and there all the same size , front and back.

 

The darker wire is usually the negative and the brighter is the positive or positive will have a white line on it and negative will have a black line. The wiring colors should be the same as how they are wired to your cd player harness if you have an aftermarket one.

 

you can also take a small cell battery like a 9volt or c battery and connect the wires to + and - when the speaker makes a popping noise you have found which is + and which is -
