After a quick search of the net I cant find much info on active crossovers... I keep seeing a few of the same ones over and over Kicker etc.. What would be a good choice in an active crossover if my headunit isnt capable? I dont want to spend an arm and a leg on the crossover. I just think I can get more for my money running a do-it-yourself mid/tweet combo over a tradition comp set, but have no idea where to start with the crossover!
