KiKaZz74 Posted January 29, 2016 Report Share Posted January 29, 2016 If ur running passive ur wasting your time. Crossovers negate any useful TA. And that tried to apply to both sets unless you have each piece ran on its own channel. Basically TA is only useful in an active setup with no rears. Passive covers are tough to work around.

arcaudioman Posted January 29, 2016 Author Report Share Posted January 29, 2016 Yeah to run 2 sets of components in the front alone. I would need another 4 channel amp. Not really looking into that right now. But if I were to do that, would it make THAT big of a difference in my sound? Would my amp push too much for my tweeters? Could I ever properly align 2 sets in the front stage? I have 1 6.5 in the door, 1 in the kick, and 2 tweeters in the door panel up by the sail panel (no Fence pillar pods) on each side Link to comment Share on other sites More sharing options...

3vil Posted January 29, 2016 Report Share Posted January 29, 2016 Try this. Measure the distance to the speaker closest to your headrest (or whatever point your measuring from) and call it L. Now for every other speaker measurement subtract L from the total distance. Input those values into your T/A settings. Example: your driver rear is closest at 21". Your driver front is 23.7", so take 23.7"-21"= 2.7" so enter that value for FL. Link to comment Share on other sites More sharing options...
arcaudioman Posted January 29, 2016 Author Report Share Posted January 29, 2016 See alpine said the opposite, they said take longest measurement, then subtract the other speakers measurements from that and input the answer from said subtraction for each speaker Link to comment Share on other sites More sharing options...
arcaudioman Posted January 29, 2016 Author Report Share Posted January 29, 2016 I will definately give that a shot though, thanks Link to comment Share on other sites More sharing options...
3vil Posted January 29, 2016 Report Share Posted January 29, 2016 I think I screwed that all up after reading my manual for my alpine hu (which is not the same model as yours). It's been a while since I played with my T/A settings. But it looks like it should be farthest=L and each other speakers T/A should be L-(speaker distance) just like what you were implying. I apologize for any confusion. Link to comment Share on other sites More sharing options...
arcaudioman Posted January 30, 2016 Author Report Share Posted January 30, 2016 When I zero my closest Speaker and input the differences is where I believe sounds best. After hours of tweaking I think it's finally done. Thank you for the input guys Link to comment Share on other sites More sharing options...
3vil Posted January 30, 2016 Report Share Posted January 30, 2016 I ended up doing something similar. I took all my measurements and converted to m/s, entered those values and save under one of my t/a profiles, then started tweaking to move the stage around and widen it. After messing around a but I'd save that profile and then compare it to the first one. I did this over several mornings in my shop's parking lot, so I wouldn't have listening fatigue affecting my decisions. Link to comment Share on other sites More sharing options...
