It's easier to adjust on the headunit vs. the amp, also more often then not, the headunit offers more adjustable slopes then the amp does.

so do i turn the amp crossover all the way up, then just use the hu crossover?

set the ones on the amp all the way up, or use the all pass if there is a switch for it. controlling it from the deck is better.

cool, one more question, i can turn the amp up or down from the hu, its a pioneer p3900mp, should i turn the gain on the amp up? i was told to keep the bass boost down as low as possible because it reduces distortion, which is same for the gain but since i can control it from the hu?...

As for the crossovers; You can use both or either. It's user preference. Some prefer the headunit as they can just sit in the seat & adjust it. But the amp xover can be beneficial aswell since it should be infinitely adjustable within it's bandwidth whereas with the headunit's xover you must select from predetermined frequencies. And depending on the circumstances it could be beneficial to use both.

The control on your headunit is not the same as thing as the gain on your amp. Read the gain setting tutorial for a start.
