I have 2 E112s in my system. They are between my preamp and amp using the internal high pass cross over. You will want to use the JL’s internal crossover as it does a very good job. You will have to set each volume on the sub during setup though. However this could be a good thing if your room is not symmetrical.
You can can turn the crossover off (using the same input) but it is a full pass through with no filter. You could then use a different crossover but you would still need to use the volume control of the subs. I guess you could set them and use the external crossover control’s volume line a pre amp but that just seems like added junk in the system to muck up the sound.
