[QUOTE="keep_hope_alive, post: 7791224, member: 576029"] what i do is create an excel table that tells me what the difference in distance is between the closest speaker and every other speaker. so, for each channel, measure the distance from your head to the speaker voice coil. then figure out the difference between each speaker relative to the shortest distance. that is what you use in the head unit for settings. after that, you can tweak to shift the sound stage in horizontal and vertical position. this is best done with a test disc, like the IASCA discs. using any random song isn't useful. if you don't have a test disc, you can listen to some select songs on a home reference system, where you can sit perfectly equidistant between some nice monitors. then take notes on the sound stage (instrument placement, singer and backup singer placement, etc). then listen in the car. i've found it's best to start with measurements, then tweak from there.
