I have got a black 02 clio,

replacing my stock speakers with infinity kappa's, the adaptors broke off with the speakers, i am now confuse with what wire goes to which point ? the + or the - ?

in the front left, one wire is orangy and the other is browny. On the driver side, one wire is purple and green. In the rear, the wires are green and brown and blue and brown.

I am completly confused and don't want to mess it up. i have read previous wiring forums, and have tried to look at the previous adaptors which were on the stock speakers, but can't work it out, can someone help me ?

Liam :)
