i somewhat understand how to make the audio control 2xs crossover module, from 3000hz+ (oem its 90hz- 22khz or w/e_

now the OEM low pass module is for 33hz-90hz, now do i use the same method for making this module(PFM)?

 

If you look here on page2 it tells you how to make your own crossover modules with resistors. The high pass and low pass use the same formula and resistors. Crossover Manual

Don't sweat that this is the manual for a Concert series - the crossover info is good for yours as well.
