which wire is positive

I was just wondering if you guys know which of the factory speaker wires is positive the white or the black. thanks

 

do you have the JBL system? which speaker are you asking about?

 

no jbl system. the factory wires that comes out of the doors and goes into the speakers.

 

I got this information off of the crutchfield website so I am not 100% sure that this is correct.

left front (+) = pink but blue at the speaker
left front (-) = violet but light green at the speaker
right front (+) = blue
right front (-) = light green

left rear (+) = Black but red at the speaker
left rear (-) = Yellow but white at the speaker
right rear (+) = Red
right rear (-) = White

 

That looks to be the same information they gave me over the phone.

 

black is ground. you can use an ohm meter on it to double check. the doors were a pain in the ass, cuz the wires came through the tweeter then back to the woofer. dumb setup, took me quite a while to figure out.

 

thanks guys i looked all over the place and couldn't find this info.
