I understand...I'm a very methodical person. I try to take into consideration the science as well as the fact that there isn't any real way to guesstimate what will happen.
Car audio is one big guess. But I certainly understand cause and effect in this specific matter. Since most people don't have any idea what they're hearing anyways, they don't notice cancellation, second and third order harmonic distortion, etc, etc. Even if they do notice it and it's technically bad...they usually think it's "good" just because it sounds different. But in the end if they're happy it doesn't matter!! So I pick and choose when I chime in. I see this as a potential bad circumstance for the op that I'd like to help him avoid.
I just like to try and educate those who have questions. Your opinions are definitely welcome and thanks for chiming in! Hope I don't seem like too much of an ass D:
