where to get them or how to make them

Essentially just a capacitor in line with your speaker, creating a 6db/oct highpass.

http://www.the12volt.com/caraudio/crosscalc.asp#ccc - plug in your speaker's impedance and what crossover frequency you want, and it'll spit out at you what size capacitor you need (C1 is what you want, don't worry about L1)

high like around 200hz ish

175hz - 250hz

Depends on the speaker, really. But that would be the general range I'd shoot for. Hell, for no more than caps cost, you can buy a couple and try them out and see which you like best.

you can get a pair for like $10. they do actually work. i used i believe a 250 hz. on my 4x6's one time and they worked well. www.crutchfield.com sells them and most audio shops.
