Head Unit

 

Sounds like your system needs to be completely tuned, you would have lost not just your crossover settings, but your eq and time correction as well. I would go back to the dealer, have them show you what they are doing and why as they tune it, then when you get home write all the settings down because Alpines lose all those settings any time the head unit loses power even for a few seconds...which is extremely annoying. So you will run into this problem again, and should be prepared for next time.

 

Thanks. From the other threads that I searched, I get the idea that I should still bring it back to them, but I'm also betting that it can't be that hard to tune.

 

Nope...it's not that hard, it just takes time and and a good ear. If you just want to make it sound passable for now try these xover settings....this should at least be a decent starting point to experiment from.

Front - HiPass @ 100hz, 12 db slope (assuming 6.5" mids)
Rear - Hipass @ 140hz, 18 db slope (assuming 5.25"s in the Spods)
Sub - LoPass @ 100hz, 18 db slope

*** This assumes you aren't running full active to your front speakers and that you have separate passive crossovers for your components, do this at your own risk if you're unsure, because if you crossover your tweets at 100hz they will just go pop and need to be replaced ***

 

I was just looking through my manual to tune my system. You should reset the Alpine HU. Just push the small button for 3 seconds.

 

Thanks for the data as a starting point. I am also trying to use the iPersonalize feature of the Alpine website to change the settings.

The front focals have seperate tweeters and (I'll check first) passive crossovers in there.


Where is the "small" button on the unit? Really, REALLY small (as in I might not otherwise find it) or just small for the 57 features that it controls, like everything else on the unit.
