Time alignment is important to creating an SQ system, and it is usually accomplished using head units or external processors with DSP functions.

time alignment is more for highs than bass, im sure its possible but ive never heard of using it for subs. basically it puts a delay of a few miliseconds on each speaker and the amount of delay depends on the position of the speaker in relation to the listener. this makes it so that the sound from each speaker gets to you all at the same time and tricks your brain into thinking that the sound is perfectly centered on the sound stage, which is one of the hardest things to achieve in a car because the speakers are in messed up positions all through out the car.

time alignment is less important with subs because sub bass is not very directional so its harder to pinpoint the exact position of the subwoofer just by hearing it. the only benefit i can see by having time alignment on your subs would be if you had more than one sub and they had to be in different locations, like if you had subs in each door and one in the trunk or back deck.

Usually the sub signal is considered "zero" and time alignemtn of other channels is refernced from it.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
