Let's Seperate Myth From Fact....
A car audio install is about overcoming the challenges of a car and the audio deficiencies! Proper placement negates time alignment.... Question here.... Would you rather an installer that takes the time to install things properly or just rely on technological (and easy) bandaids like T/A?

TA can only do one thing, and that is delay the time a sound is produced by a speaker, it can not move it to the left or the right, it cant enlarge the air volume of the speaker enclosure, it cant vary port size/length, it cant make a Focal sound like a Morel even with EQ. It absolutely can not make up for a poor speaker location and account for glass reflections.
when you decide on your installation you select weather you want speaker reflections or you want to do near-field listening. The windshield and shiny hard vinyl can be your best friend or your worse enemy depending on your install. TA cant fix reflections
Of the typical DSP features (Xover point and slope, EQ, and TA) I would usually put TA on the back of the bus, BUT it is an important piece for some installations and even with seasoned competitors they misalign TA. A properly designed system will make TA pretty much optional. I find its best functions are to force a system to center. The overall sound (pitch) is affected a bit as well with TA.

For those who are strong proponents of time alignment - are your goals for accurate sound reproduction skewed to only from the drivers seat at the expense of the accuracy from the passengers seat?
Not a bash, just a question.

Who cares about the passenger? Lol. Actually my setup can selected for whatever location you chose as a listening point. To those that say TA and EQ does not solve auto audio issues but is just a bandaid my only reply is duhhh. There is no other purpose for these things other then to help with short comings due to the car environment. I like car audio but I don't like spending 5k and endless months on an install when I can do it in a week with proper sound deading decent components and good processing and TA.

no as it doesn't shift the time (add a time delay) of the signal, it shifts the phase of the driver... which is also what TA does indirectly (it shifts phase mechanically not electrically) which is why there are shifts in EQ with TA (not huge but noticeable).
