On a 2001 ext cab, I am replacing the door speakers. I think the wire colors on the left door are grey and brown, and on the right door one wire is green and the other is blue. Can anybody please tell me which wire color in each door is the positive?

 

Doesn't really matter but as long as you match up each speaker with the same wiring. Usually the wire with the black stripe I use as negative on each speaker, but like I said as long as it is the same on each speaker. So it could be vice versa.
