If you have component sets, they come with passive crossovers.  You'd run the amps full range into the crossover networks or set the high pass filter at 80 or 100 HZ to protect the component speakers from playing sub frequencies.

If you want to run active (i.e. not using the passive crossovers) you've got a lot of work ahead of you...

I want to run active.
