okay hers the deal. . i have 2 massive p3000s going to a single sub. so to set the amps in phase so the voice coils are moving at the same speed we had to use a tone generater. i took my sub out to paint the box, and i hear that even disconecting the speaker wire can throw the amps out of phase again. . anyone know if this is true???
