The head unit and amp should have a crossover built in of your talking about separating frequencies

Most amps now adays have crossovers built in...what do you need them to do?

Depends what headunit you have

tell us make/model of the head unit and the amps. better if you include pics of the amps controls.

most amps have crossovers. for the most part you just use a high pass crossover on the speakers (around 80-100Hz) and a low pass crossover on the sub(s) at the same point as the speaker amp.

What speakers also.

Lpf blocks highs

Hpf blocks loWs.

Band pass filter (bpf) let's a RANGe of frequencies through to a speaker.

Sub uses lpf. Usually set at 80hz. This means the filter will block anything over 80hz from going into you're subs.

mids.

Are they coaxial or is it a component set.

Coaxial speakers usually have hpf set at 80hz. This means anything under 80hz will not pass to the speakers, and the crossover built into the speaker will hpf the tweet in the middle.

If you have a component set, usually the mid is band passed at 80hz-3.5khz, and the tweet hpf is set at somewhere around 3.5khz.

Make sense?
