The "crossover" is where the frequencies are separated. It is what is responsible for making sure the "bass" is directed to the door subs and not the main speakers. Also, it ensures the mids/highs are directed towards the 4 regular speakers and not the subs. The crossover "point" is simply at what frequency (or musical note I guess you could say) is the "middle point". At the crossover frequency, the signal is sent equally to all speakers. Below that point, the signal is sent only to the subs, and above it it is sent only to the main speakers.
Oh, off subjet, didn't realize you were from Sweden; Thats cool-that is where the amp9 kit I bought came from!
