hang a piece of tape where the middle of your head would be and bust out a tape measure.

you then run the distances through a formula and enter the resulting number into the HU.

ok so its from speaker to the middle of my head, and about the formula i think its not necessary because you can input the values on each independent speaker by distance (in/cm)

thansk for your help

the idea is to have the output from each speaker/sub, arrive at your ears at the same time, becuse some speakers /sub are different distances from you, the time alignment feature can adjust the timing of each speaker. you need to delay the speaker closest to you the most and others less, and the speaker farthest away has zero t.a.

trust your ears not the settings, if you get it right music will start to sound clear and 'up front' not 'behind you'.

i tried today and i really improve the sq, but now i have to set the gains on the amp its a 600 something mtx and its 4 channel but i runing in to 2 bridged and feeding 2 bostons sl80 front stage but i think the gains on the left and right its not balance going to have to set the gains whit the multi meter to have them balance

bump this thread to please explain why my Alpine HU Manual suggests to set a lower

ms delay for my front speakers than my rear speakers. It seams bassackwards.

Maybe by LOWER it is referring to "lower distance to the listening area". Such as inches.

is everybody using time alignment? i dont think my headunit has that feature........... i will be getting a Arc audio IDX/XEQ for processing, is time alignment necessary ?

Because you want the sound of your front stage to arrive at your ears before the sound from the rears do.

Lower ms = less time before the sound reaches your ears.

Won't the distance differential take care of that?

And, I want my sub reaching my ears at the same time as my

fronts too. How the heck do I do that other than delaying the

fronts until the sub gets there?

you need to lengthen your sub distance...because it gives the bass waves time to mature //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif your bass will sound richer and lower...much more detail than before...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif but you have to find the point where it matures...you can go to far as well....

...what? Give your bass waves time to mature?

Don't delay your subs at all, if they are in the trunk and far away from you. Delay your front and rear speakers by measuring the distance difference between them and your sub.

A = (B - C) / 34

A: Delay time (ms)

B: Distance from listening position to furthest speaker (cm) (your sub)

C: Distance from listening position to the speaker to be adjusted (cm)

For example... Example:

If you're in the drivers seat,

B: right rear speaker 100cm

C: front left speaker 50cm

Delay time = 100 cm - 50 cm / 34 = 1.47ms - figure 1.5ms.

You need to do this for every speaker independently. You may be surprised; in some cars, your rear speakers are closer to your head than your front speakers are, and you would actually delay them more than your fronts. Be prepared to tweak it a bit, as you may not sit exactly in the same spot when driving around.

This helped out a lot. I set the closest speaker to delay to where I figure the

sub should get there. Like 77 inches worth of milliseconds. Then the other 3

speakers are reduced by an amount in accordance with their distance. So

the front right is like 62" delay, the rear left is like 30" and rear right is like

25" and the subs are 0" worth of delay.

Sounds way better. I reread the manual too, I had it all wrong to begin with.
