at the moment, with only a 4ch amp u cant play active yet.

active means each speaker gets its own amplifier channels.

tweeter got its own 2ch, mids got its own 2ch and sub its own 2ch (or 1ch if using monoblock)

when active you will not be using the passive crossover already, speakers connect directly to the amp.


so in conclusion, with this system u dont really need an electronic crossover.

no u dont need a xover if ur using coaxials

if ur adding tweeters and want to use the coaxial as a midrange, then suggest to cut the wire of the tweeter in the coaxial, and yes u will need to add a passive xover to run the midrange & tweeter
