The reason why for the EQ, like the fact that I'm able to adjust all the settings right there on the spot instead fiddling around with buttons on the headunit. And I only got it for 75 bucks...lol!
You can adjust frequencies for the front speakers ONLY if you are running an external amplifier. in the example described above you would only be able to control the subwoofer with the EQ.
To control all speakers you would need to run the outputs on the EQ to amplifiers for each speaker or speakers you wish to control with the EQ. It cannot change frequencies put out by the head unit directly to the front speakers.
More visually, to wire for the sub your wiring will be like this:
Head Unit -> Speakers
Head unit -> EQ -> Amp -> Sub
If you want to control all frequencies:
Head unit -> EQ -> Sub Amp -> Sub
Head unit -> EQ -> Speaker Amp -> Speakers
