[QUOTE="ciaonzo, post: 6861098, member: 607015"] If your HU doesn't have any filters built-in and you don't want to buy an external crossover unit, you need amplifiers with built-in crossovers that will facilitate the not-so-common range of frequencies between the tweeter and midrange/midbass (usually a 500Hz to 5kHz variable adjustment range), as well as the ability to create a bandpass filter for the midrange/midbass. Some amplifiers have this feature but most do not. It's not necessary to have an amplifier that has a bandpass filter, you can create a bandpass filter by using multiple amplifiers that each have the ability to cross high or low for the power outputs, as well as the ability to cross high or low for the RCA outputs to feed the next amplifier (assuming it has them). If you use three 2 channel amplifiers that each have the ability to do that (including at least one that has the 500 to 5k adjustment range), you will have very flexible active capabilities. Countless people have been doing it that way since way before head units ever had built-in filters. [/QUOTE]
