IMHO you should have a 100 amp out alternator to support the vehicle, 4 lights and a little in reserve for the future.
Add up the vehicle's requirements, ad in another 40+ amps for the lights and you have a minimum alternator output.

The lighting alone, if all on at the same time will draw approximately 76 amps, add in another 45 amps for everyday driving and you are almost max'd out.
If KS_FX4 has the 130 amp alternator then there should be no problems but if it is a low output 65 amp then some where down the trail there will be, there will be...

If you consider that maybe your system is putting out 13.8 volts you are correct and you can drop the amperage draw to 65 amps, but with all of that wattage the battery won't last too long unless you have a high output setup. (the 13.8 volts the battery/alternator puts out is not under a load, when the lights are on, the stereo is on and the amp is pounding out enough bass to pop the windows the alternator will either be working it's heart out or blow up.
That's 75 amps at 12 volts, a load for sure but on a 65 amp or even a 90 amp alternator it's questionable how long the lights will stay on and the engine stay running.
If you have anything under 100 amp alternator, IMHO, you are in trouble when the lights come on, even with an extra battery.
If you want to run two batteries with isolator, then that will separate the vehicle operations battery from the high output accessory battery, you can do it but it will still be a load on the system without a high output alternator.
I am running over at the mouth again... later,

I am not sure how to determine this. Have a buddy at the local Ford dealer check it out, go to an auto-parts store, got me.
I am in the same boat you are, I need to determine the output of my alternator because I will be hooking up have six lights, four 150s (long range and driving) and two 100s (fogs)
if you do find the code for the alternator output let me know.
I hope someone will cut in here and tell us.

Can't argue the statement, I can't find them on the web, so i will back off on this but I would have sworn they were 150 w setups.
I have to check the package again just to make sure.
Sorry for any confusion here ...
