assuming your car is RHD and has the base audio system with no separate amplifier (all speakers are driven from an internal amplifier in the head unit):

front left subwoofer
+ red/white
- brown/yellow

front left mid range
+ yellow/green
- yellow/brown

front right subwoofer
+ red/blue
- brown/white

front right mid range
+ blue/red
- blue/brown

rear left mid range
+ black/red
- black/violet

rear right mid range
+ yellow/black
- yellow/brown
