I was doing the connections for the LOC today and it's pretty straight forward but i have two cables that arent connected yet. On the output side there is a yellow, blue/black and blue cable. The LOC manual says the yellow cable is 12 v power, but is it constant or switched power?
constant
The black/blue cable is for ground, but there is another ground on the input side. Can i just ignore that cable?
ground it to a clean piece of metal in the dash. you can add some wire to make it longer if needed. never hurts to have an extra ground. if it isnt needed there will be no current in it, however if it is needed and you dont hook it up you will be pulling your dash back apart.
The blue cable is remote for the amps; can i use one remote wire that came with the KnuKoncept amp package and just split the wire in two ends so i can connect them to both amps?
if you are running two remote wires just connect them both to that end of the wire and have two wires running back. if you are going to daisey chain from one amp to the other just run one wire back. and you can use a jumper from one amp to the other.

Thank you for the guidance on the LOC. I picked up a Ported box from Sound Ordinance. I'm setting it up right now but I don't know how ohms means or how to connect it to the box. Can you guide me on what diagram to follow or the connections I need to do. I'm trying to attach pictures but it won't let me. What I have on the sub is two red and two black push terminals. At what ohms do I set it, and how do I connect it to the positive and negative cables of the box?

what amp and sub did you go with? ohms are the nominal resitance of the coils on the subwoofer. you have two of each terminal because you have two coils. It looks like you have dual 4s. so you are going to want to wire them in parrallel.
this video show parrallel and series. do it the parrallel way.

thats a pretty good video there. it will show you how to do it. its the first part he talks about. make sure to stay positive to positive. they may not cross. most do, but they may not.

Is this good? I attached a picture. The black push down terminals are negative and the red are positive. The jumpers I assume have no polarity. And the black wire with the grey line is negative, and the grey wire with the black line is positive.

do you know the tuning of the box? if not get some measurements before you put the sub in.
overall measurements of box.
if round port:
diameter of port and length
if square:
hieght, width, and depth or port.
