Shouldn't be necessary. The 8 will just sum them anyway if you do. So if your fronts are full range and your rears are full range, or anything less than full range, it will just add everything together and you will end up with...full range.

You "unf^ck" your factory eq curve to flat, then you tell the 8 what your speaker config is, you tell it what freqs to cross at, you tell it what slope to cross those freqs at, you verify that you are getting sound from the places you told it about, then you calibrate by wearing the microphone headset and following the directions on the screen ("look straight ahead") while the unit generates sweeps and tones. It says done, you enjoy music that seems to come less from the speakers themselves and more from a general area of the vehicle (hopefully up and centered over the dash).
(1k is very low BTW, I'd be careful with that.)
