Advice needed for signal seperation

I was looking at a suggested division of frequencies for my speakers...

As suggested: A/D/S tweeter/woofer components 350hz+ MB Quart midbass 70-350hz. Sub to 70hz If I am using my Alpine head unit 3-way setup, the control I have for setting crossover points are as follows: Low: 20 Hz - 200 Hz Mid High pass: 20 Hz - 200 Hz Mid Low pass: 20 Hz - 20 kHz High: 1 kHz - 20 kHz So I can set low to 70 Hz and bypass the crossover on the amp for the sub, no problem. I am not sure how I would run the other channels. I can set the mid from 70-350 Hz to supply the Quart's. But then I will have a gap between 350 and 1K. And If I am going to power the a/d/s using the xo, I'm not sure how to get this to work. If I let the a/d/s's xo determine the crossover points....I'd still need to feed it 350 and up. I want to biamp the a/d/s/ also......hmmm... Perhaps I can use the crossovers built into my Orion 500.4 amp. They allow 45 - 5k high or low pass. I could use the orion for the midrange. Use one side to run the Quart's using the Alpine's mid crossover set from 70 Hz to wherever the a/d/s passive xo sets its cross. On that side I will then use the Orion xo set for low pass at 350. Then on the other side for the a/d/s in the kick, I could set the Orion xo for high pass at 350. It would not matter where I set the Alpine xo at this point because the a/d/s will cut it off where it needs to. Then I could run the high side of the Alpine to two channels of the Eclipse amp for the tweets. Then I can bridge the other channels of the eclipse to power the sub if it lets me bridge it like that. I'll have to check.

But I have also read that the Eclipse amp is best suited for midrange and up. 

Any suggestions out there?

Everything looks good, run the high pass at 350Hz and let the passive crossover that came with the comps seperate the Mid and tweeter. Paul
