its just that the speakers move opposite of each other.

With music as a source, you can not see that a speaker is out of phase.

Do you have a 9-volt battery? Disconnect the speakers from your amp and connect the speaker leads to a 9 volt battery. If they both move the same direction they are not out of phase.

I really do not know the answer to that question. A 45 Hz bass note moves the speaker in and out at the rate of 45 times a second. I am sure you have one woofer that on an extended bass note appears to be moving in, and the other appears to be moving outward. I have seen this many times, I mean many. Never had a need to figure out what caused this phenomenon.

Timing issues due to differences in DCR and inductance, as well as series resistance from speaker wires, can cause this.
