the rear positive are the dark colors

the front positive are the light colors

use and ohm meter to check to make sure you should read about 4-8ohms on each pair of wires

the other trick is to simply open you trunk to check the colors going to speakers

and remove front speaker grilles and speaker in the dash...it is easy screw driver and 7mm heads

you can also use a 9volt battery to pop the speakers.....be careful
