Crossover explanation please,

I know this topic can be problematic,my first question is :my passive crossovers have a little lamp inside that sametimes lights up,why does it do that that ? The amp powering them up is a RF and the tweets are also by RF.

My 5.25" mids run thru an active crossover that is kinda confusing to me cause my Mb Quarts run happy between 49 hz~32 khz,with crossover requiered to be at 4200hz but my electronic crossover has this setings:Mid cut(180hz),hi pass at 180,120,80 or flatt,the low pass is :flatt,5k,3.5k,2.4k  so how do i get my proper setings here ? ...same for the 4" mids with the exeption that they work best between 62hz ~32khz with the crossover point at 3700hz.

What i don't understand how do i get this numbers like 4200hz and 3700hz when my crossover uses hi-pass and low-pass with different numenclature,can somebody help please.

Thank you all.

I need to know the specs Ie the resonating frequency and range each of your speakers are tuned for so I can assist you further.

Thanks for checking my posting,the electronic crossover is a sony xec 1000/s,but i only this one for my 5.25" and 4" Mb Quarts my mids,the tweets are RF powered by an RF amp,the rest gets power from 3 Nakamichi amps,one being for the subwoofer,BTW the sub is an ads 310rs.My crossover has setings for the sub like this:low pass 180,120,80 and 50.
