Output Impedance

[rinchan6]

Hi guys, Im trying to achieve an output impedance of 4 ohms using 3 speakers, a woofer, midrange and tweeter. I would like to connect the woofer to a subwoofer filter so I cant series it with any other speaker. My problem is I cant figure out how am i going to wire them :/ this might be a simple one but I cant really figure it out.

When using a crossover network, you don't put the different channels in series. You put them effectively in parallel. Each channel (low, mid, high) presents it's impedance to the driving amplifier only in the respective frequency band.

Here is some stuff to read.
