This is wiring for a car speaker, everyone says that the polarity doesn't matter if it's only 1 speaker but does for multiple, this one has purple and brown wire and the other side has blue and green wires, so colors wont help at all. I have a Multimeter and was wondering how do i test which of these is positive and which is negative?
- TL;DR
- Car speaker wiring which is positive(can't go by color)?
