Hi guys,

I just installed the 9815 HU; using internal amp and factory speakers. However, I'm having heck of time adjusting the i-Personalize feature since I'm pretty new with stereo... :(
Can anyone suggest the best setting for all the modes(Time Correction, Crossover, Parametric EQ)? Any advice would be appreciated. Thanks in advance!!

I do not have specific experience with that unit, if you are havin that much trouble, go to a local Alpine dealer and have them show you how to use the features.

I think i-Personalize is setup so you download a set of specs, based on your car's model/make, and you burn it to a cd. You then use that cd, and it loads into the headunit pre-programmed with a custom soundfield. ...I think.

I know what the i-Personalize is capable of; it's the setting data that I'm having trouble with. Especially the Crossover part... A friend of mine suggest to set the front and rear speakers to cut off at 80Hze, but since I have no idea what frequency could the stock speakers hold up to, inappropriate setting may damage the speakers?

Details, details, details.

Post what you're running so we can help you.

If you're running 4" up front, cross them over at 75hz. 5 1/4" @ 65hz, 6.5" @ 55hz.

For the rears, if you're running them, cross them over at 50/55hz.

If you're running subs, cross them over at 80/85hz or 100hz.

On the other hand, if you've got a component set up front, and you're using an external passive crossover, just set the front crossover on the headunit to off. Same with the rears.

I keep the crossovers on the front/rear OFF, and the non-fader lines off. I send a full signal to my amp's sub channel, which crosses over the subs @ 100hz. I send full front/rear signals to the amp, and I have the amp's crossovers off; I let the external crossovers deal with my front 6.5" and 3/4" tweet.

FYI www.alpine1.com has a time correction calculator on their website now, in the i-personalize section. You just measure how far your head is from each speaker, type those measurements in and it tells you what time correction you should use.

Sorry I didn't make myself more clear. :p OK,I'm running Alpine 9815 with it's internal amp, and original stock speakers(which are 4.5" front and 6" rear I think?) without the 5x7 sub, that's all, no external amp, no aftermarket speaker nor subwoofer.

Below is my current setting, any better suggestion?
