GT0628 Speakers

[heavylevy]

Hi there
Just done the GT0628 front speaker change but try as I might I can't find out which are the + and - in the original wiring loom I have checked the fact sheets and various threads but none seem to mention it.Im guessing maybe it's not important but I don't want the speakers to be out of phase.the plug for the speakers in the door is sort of a T shape I have guessed that the | connector is the minus. Please help.
Brilliant forum by the way.
Cheers heavylevy

If you've got a multimeter, with the speaker disconnected, measure the resistance between each connector and earth. The one with least resistance should be negative
