Either sub is fine. Get the biggest one you can fit at the price you can afford. As for the wattage distribution, it's doesn't work like that. The power to run above 3k Hz is only about 10% of the total power needed for the full system. Relatively speaking, the wattage at max is 125 x4, the tweeter in one each of those corners account for about 10-12 watts. The rating on the actual driver, is relative to what they can handle, not what they are given. The crossovers that you will install for the speakers will take care of dividing the frequencies between the two drivers, nothing else to do for that, install, them hook them up. good to go' The issue you speak of, is not rectified by use of a mid driver. The issue is related to lower frequencies playing in the midbass drivers that they really not designed to handle. Setting the crossover on the amp will take care of that issue. for the front and rear speakers, you'll select the HP (high-pass) setting and I would initially set them at 75-80hz for the front and 200 hz for the rears as that is the fixed HP frequency for channels 1/2. Your subs will pick up from there. I would not go any higher than that given that your sub will be in a trunk and trying to get it to play up to the higher midbass frequencies will be difficult mounted in the trunk. One other note, for $9 more can get the matching Recoil mono sub amp (recommended) which puts out more power allowing you to set the gains a little more conservatively insuring that you have extra headroom and the amp won't have to work so hard.

I'm kinda guessing but looking at the amps I would initially set them as follows:
THe 4 channel:
Channels 1/2 set the HP filter to "ON" and run channels 1/2 to your rear speakers. For channels 3/4, set the HP filter to on and put it right around 12 o'clock
The Sub amp:
Subsonic at around noon on the dial, the LP filter at about 1 0'clock
BASS boost, I never use these at all but that is not to say it maynot help in your car. You should leave it at the lowest position and play with it (preferably sit in the car, at modest levels and have someone turn it up and down until you can see if you like it) to see if you like what it does for you.
As for the gains, if you don't have the ability or the knowhow to set them, it would be advised to watch a LOT of vids or flip the local installer at the local shop a cool $20 and have them check/set them for you.
