1. Are you using passive crossovers that come with the Sound Ordinance component speakers, or not?
2. Are there completely separate wire runs for the midwoofers in the doors and the tweeters that don't go through a OEM/factory crossover?
3. Are you powering any Rear Speakers?
4. Do you have a subwoofer?
For 6.5" to 6"x9" front door midwoofers, you would typically set the HPF (High Pass Filter) to 80Hz for protection and let a subwoofer handle the frequencies below 80Hz.
If you don't have a sub yet, you might be able to get away with the HPF being set to the lower 60Hz setting to help fill in the lower midbass frequencies, but this will limit how loud you can play them before distortion occurs and/or bottoming out and potentially damaging the voice coils in the gap to the magnet's backplate.
In the Kicker Key's "Bi-Amp" mode, you can only power one pair of front tweeters and one pair of front midwoofers without using passive crossovers that come with the Sound Ordinance (or any other 2-way component speakers).
We can help further once we have the information above.
