Alright this should be a short one.
My stereo and speakers were stolen and cut out of the truck and I'm trying to figure out what wire for the speakers is positive and negative. I've looked at a bunch of diagrams but couldn't find it.
I got two wires on each door (were the speaker goes). Both sides have the same two wires.
One is black with white stripes-the other is black with green dots.
Anyone know which one is positive and which one is negative?
Thanks.

 

Maybe this will help. Black with White hash marks is negative. Note how wire color changes at the connector before speaker so both doors have black with LT green dots for positive.

 

Thanks that helped immensely...its all hooked up and good.
I would have probably been lost had I even found a diagram..how do you know which wire is positive and which is negative just from looking at the diagram?..
Sorry-newbie.
Thanks again.

 

The negative wires connect together back at the radio, the positive wires stay separate.
