Hello All, I've spent considerable time and effort trying to get the front stage and sound bar in alignment and I've finally got it dialed in so I figured I'd share with the group.
First thing's first. Before trying to time align any speakers in your Jeep its imperative you get the speakers in phase first. This is much more of an issue if you're using active crossovers than passive ones. If you're using active and have the option to use a L-R crossover program I highly suggest you use it as it's much easier than trying to calculate per octave phase shifts when using a butterworth etc...
Anyhow....here's what i've got for a 2 way active setup after phase alignment set using a scope.
Front left Tweet in Factory location: 1.90 ms
Front left mid in Factory location: 1.91ms
Soundbar left Factory location 4.06 ms
Front right Tweet in Factory location: .91 ms
Front right mid in Factory location: .92 ms
Soundbar right Factory location 1.81 ms
This set up will give a perfectly centered sound stage centered on the driver
hope it helps those that have been struggling like i had.
i used a Dayton um series measurement mic and 3 different software programs to confirm the measurements. I even hooked it up to my buddy's JL audio Max tune system with 5 mics and its spot on. Good luck.
