i've looked all over the FAQ and can not find an entry on how to properly do this adjustment. Am i supposed to just twist the knob until i feel like its centered? Anyone have any recommendations? I have a 91' MR2 (two seater), and the speakers are faded to the front (Boston Acoustics Pro Series - components).

Yeah, just play with it. It will be pretty evident which to use. I thought I wouldn't be able to tell the differnce between the "clicks" but I certainly could. Just give it a shot. Every car/person is different.

Yeah, playing with it is the way to go. It seems that the bass response is the main indicator - When the alignment is correct, the lower frequencies arrive in phase, and thus sound louder and 'punchier'.
