Can you get a bandpass filter from the kicker kx3 crossover? I understand that both front and rear crossovers are high-pass, but say I wanted to use the front crossover for my tweeters and the rear crossover for my midrange speakers. Would I get a cutt-off point for the rear crossover (say from 400-2000 hz) so it wouldn't play all the high frequencies? Or do both front and rear highpass crossovers play the same frequencies?
