Tip:

Time Alignment (for 9887): The furthest speaker is set at 0in/cm. The next furthest speaker = distance from furthest speaker minus the speaker measured. i.e. Right Rear is 5 feet from driver and Left Rear is 4 feet from driver. Set 1 foot in the alpine head unit for the distance of Left Rear channel and Right Rear is set at 0 feet.

Do this for all the speakers. Also, as long as tweeters are within 6 inches of the mid the speakers can be considered "one unit".
