2010 kia sportage firewall hole

i have a 2010 kia sportage v6 2.7L. i am trying to run my 4 guage battery wire threw the firewall, but the mailn problm i am having is... on the engine side it looks like there is a spot to put a hole since i did not find one, but on the inside i have 3 comp modules all mounted in the same general area. any suggestions on what to do? i have been installing for many years, but its this one that i cant even try to locate  some what of a clear spot to do it. thanks in advanced....  

If your vehicle is automatic the drill through where the factory clutch would go. if Manual then about 4 inches lower than clutch area

all the computer stuff is all mounted there 3 of them
