The phase control will help with any delay in the lower frequencies , basically if the low end seems out of sync with the midbass and vocals.
The crossover will cut the frequencies above or below what u want the speaker to play.
The level control { IS NOT A VOLUME CONTROL } is there to match input to output levels.
Your alpine has a bass engine built in to help set up and a basic eq for the midrange.
If your stuck give me a shout.

Set the vibe x over to @70hz that way it should cut most signal after 70hz
your headunit has a bass engine with boosting points , if its lacking low end up the 50hz setting.
Similar with the mids , the headunit has a basic eq to up certain mids frequencies , your just gonna have to play around with it til you get the sound you want.
You can buy bass blockers to cut low bass from your mids if its distorting.
Come up to the big audio day at icedot.com in mk nxt sunday or i can pop over if you cant get it sounding how you want it.
