hey guys i asked this ? a while back, and i couldnt find the post, maybe its gettin to late! Anyway, i really need to know which color wire is neg and positive for the factory wiring in the doors(speaker wires) If anyone out there knows please write back or pm me.

 

no one knows this? do you know where i would be able to find this out, thanks

 

Disconnect your speaker. Take a 9V battery and touch its positive and negative to the terminals on the speaker, using 2 little pieces of wire. If the cone moves outward, the positive and negative are in phase and you can tell which is which using the battery. If the cone moves inward, your battery wires are reversed at the speaker. Hope that makes sense.

Well, although it's a little off topic, you might want to test it using either in-phase OR out-of-phase...your imaging will be a bit different, but you may like it more one way than another.
