Thinking about it, I think I know what you are talking about. I think my deck will do something similar. It will adjust the timing, or send the signal to the farther speaker before it does the closer speaker. By doing that it moves the "sweet spot" to the drivers seat or wherever you want it. While this works with speakers running off the deck I would have to assume it would not work while running speakers on an amp. Please explain how to wire something "out of phase" if you would. Thanks!

Im not looking to win any competitions, I just want to fill in the missing sound.
