Trying to Tune my Audio System with this HU myself Want to learn how to tune by myself. Basically i need a tutorial about the basic step to tune with Alpine 9887 as the HU or is there any web that provide such info?

The crossover points are going to be driver dependent first, then tailoring to your car.

quoted from Andy Jones from another forum

"80 down subs
80-250 midbass
250-5khz midrange
5khz and up tweeters.

Then start playing around. But that's a good safe starting point."

I know you're trying to help, but that won't work. First off, the 9887 is only 2-way+sub. Second, it depends on his drivers. My mids would sound like crap at 5k.
FWIW, mine is 63 on sub, 80-1.6 mids and 1.6 on tweets. My advice would be see how low you can go with tweet xover (and still sound good), then bring up mids. Play with it from there to get what sounds best in your car. Don't be afraid to gap frequencies. Good luck.

Sublimez: 9887 able for a 3-way system theres a swicth below for a 3-way setup.

Thanks guys (Sublimez & EAllen), will try out your method and play around with it ...

That 3-way is 2-way+sub. There are only 3 sets of outputs...

one more thing. front=mid,rear=tweeter. It seems counter-intuitive, but it's buried somewhere in the manual.

Which drivers are you using and what kind of car are you installing them in and which locations? We can work on it from there if you still need help.

@ Sublimez: Will try that one =)

The Domination speakers look decent. Are you planning on running a sub? The Alpine will do 3-way, but that leaves you with no subwoofer signal at all. Judging by the driver specifications, I would start with the High Pass on the tweeter at 4kHz, play the midrange from 350Hz to 3.5kHz and play the midbass from 200 and down. Most vehicles have huge peaks around 250-300, so the gap will help eliminate some of that. I know the points on the 9887 are not those numbers exactly, so just get close as a start. I would also start using 24dB slopes and change them around to your liking.
