Hi:
I also have the Alpine head unit with the time delay feature. Sound travels at approximately 1100 feet per second, or about a foot every 1.1 milliseconds. Let us assume 1 millisecond for simplicity.
What you do is determine the speaker that is farthest to from your ears. This could be either the right-rear speaker or a subwoofer in the trunk. Make the farthest speaker the baseline. For each foot that another speaker is closer to you relative to the farthest speaker, add 1 millisecond delay. I believe the Alpine units are set up in 10ths of a millisecond on the adjustment values -- meaning a value of 10 on the delay setting equals 1 ms.
I only put delay on the front speakers. I have the right front speaker set with 2ms delay and the front left speaker at 3ms delay.

That would be good if you wanted the sound from all the speakers to arrive at the same time. But for a good front image you want the rear sound to arrive later. I think the rule of thumb is either 3-5 ms or 30-50 ms later than the front speaker sound.
