[QUOTE="ekincam, post: 3657483, member: 581428"] To answer your original question. Passive crossovers you just amp and they split the signal and pass it to the appropriate driver in the component set. Active crossovers, you have some type of processor that splits the frequencies and the components get a seperate signal from the amp. For example, some head-units you can go 3-way active. This means the HU will output a separate signal for the sub, mid, and tweeter. With an active crossover, you can adjust the crossover points as you see fit. On passive crossovers, the crossover points are determined by the hardware and you cannot make many adjustments. I've seen some passive crossovers that allow a +/- 2 or 3 db to the tweeter, but that's about it. [/QUOTE]
