I have some 2 ohm infinity reference speakers and want to know what the polarity of the speakers in the dash is. I looked at the sticky and the wire colors didn't match the ones in it.
use 2 wires attached to a AAA battery to the OEM speaker. YOu can test the polarity. The speaker will move outwards and the polarity will be correct. The plus of the battery will match the plus of the speaker.
Just take the bare conductors and tap them to the speaker terminals with the radio on for a second. If you here music, you are good. Or you could go buy a meter... Tapping the speakers won't hurt anything.
