you can use a 9v battery and touch it to the leads...using your pos and neg post...if in phase the speaker will push out...if out of phase the speaker will **** in

the battery is the easy way. connect a 9 volt to your leads and see if all the drivers cones move in the same direction, if so they are in phase, if not then theyre not lol

ok my speakers are all sealed up behind panels, and wires are all the way in the back. Gonna have to get a friend to look at the speaker while i play with the battery in the back.

Just trying to take care of some tuning issues.
